Lumpy Gravy by Frank Zappa
Lumpy Gravy, however, still does not present content I would choose to listen to when I want to listen to music. The ever changing melody and content feels more like an audio track that has lost its movie than a piece of content meant to be enjoyed on its own. I suppose that actually raises an interesting question: why do we enjoy movies with such quickly changing contexts and perspectives while we (or at least many of us) abhor the idea of music which is always changing and presenting conflicting melodies?

Remote collaboration
Plunderphonics
I did find Oswald's mention of imitating Bruce Springsteen to be interesting. If we recognize that imitating another musicians sound is legal while using small samples is illegal than it would appear the issue is really about property and not creativity. We talk about musicians as artists, and we talk about protecting artists' creative works - but it appears its not their creativity they care about, its the sliver of the sound spectrum they stumbled upon which proves to sell.
Along the lines of audio "property," I personally reject the argument by popular musicians that pirating music is such a debilitating crime to their industry. There was once a time when music existed but highly replicate-able media did not. Back then it was all about live performances. It was simply the coincidental invention of recording media that allowed the music industry to enter this golden age of working far less and making exponentially more money. The way I see it, we are simply returning to a place in music production where you have to work for what you make. If you want millions of dollars, then make great music and play a lot of shows. In fact, in a live performance market you want your sound to spread virally to get everyone clambering to see your shows. The "stealing" of music is not the death of the music industry, its simply the 2nd transformation of the industry that comes with an implicit marketing strategy.
I also found the reference to the public domain to take an interesting perspective. It is true that we are utterly surrounded by music and audio. Today a good question really is: How can we possibly create audio outside the context of others' compositions? We hear them almost without pause (after all silence is one of the most valuable commodities in sound today, right?). Its no secret that our ears are very sensitive, and our memories and emotional center are certainly tied to what we hear. Therefore strict stipulations about the few contexts in which a composer/musician is allowed to skate on the fringe of sounding vaguely similar to another "artist's" work seems almost inhumane.

A smorgasboard of thoughts
Sound Unbound - Chapter 1 - Steve Reich
The chapter in and of itself was Steve Reich basically giving his career in review, but what I found most interesting about his career was that he seemed to take the concept of the voice as an instrument seriously. I had heard of "the voice as an instrument" before, especially as I have actually taken voice lessons. Yet the way he used voices was totally unique. Starting in his early career when he was interesting in phasing them, and then latter when he composed pieces such as Different Trains and used speech as melody. Aside from sounding interesting it added a more tangible historical component to the piece. Another piece that I found interesting where he did something similar was "Three Tales" which he did with Beryl Korot where he used interviews as the libretto. Of course all of this stems from the concept of sampling as instrumentation, and of course that sampling is not just limited to voice. One final point I thought interesting was that he didn't like synths.
Morton Feldmen
As I read through the article I discovered on Morton Feldman I felt one of the things I recognized most was that "Morton Feldmen was a friend of John Cage".
After learning such standard facts, such Jan. 12th birth in Brooklyn in 1986, I inevitably decided to let his music do the talking for him and decided to listen to "Rothko Chapel". http://www.youtube.com/watch?v=qxSt_w2ODaQ
The initial violin certainly grabbed my attention, but I believe it was some of the initial intermitten sounds that I found difficult to identify that made it eerie to me. Then of course when the voices came in their "unique dissonance" only added to the effect. If found it interesting how majority of the time there was only one instrument playing and he seemed to initial use single instruments at a time to promote "the building effect" in the music, then finally mixed them.
One of the comments posted on the wall of the video was "listen to this in the dark". Seeing as I can be skittish that is certainly something I will not be doing ;however, I think if I were ever to make some sort of avant-garde haunted house and throw in Jean Cocteau and Mozart this music would definitely be playing.
Plunderphonics: Because "A good composer does not imitate, he steals"
In the essay Plunderphonics by John Oswald he discusses the way in which music is imitated, borrowed and "stolen". For example, he mentions how singers with original are often trying to imitate Bruce Springsteen's sound as opposed to studying his melodic contours. He brings up the "right of integrity" in relation to Canadian copyright law, and the however author can protect a work from particular distortion. However in my mind the most pivotal and interesting comment he makes in the entire article comes at the end where he states "All popular music (and all folk music, by definition), essentially, if not legally, exists in the public domain. It's a statement that I feel less compelled to write about, and more compelled to go play with and test out.
Some Supplemental thoughts on Harmonics
When searching for information about Harmonics I found multiple definitions of what exactly Harmonics is; however, in the end I found this article which related to Sympathetic Vibratory Physics more interesting http://www.svpvril.com/musicuni.html.
The article seems to be a mix of the spiritual and scientific, and contains statements such as "there is no such thing as chaos in the universe"
What is has to say in terms of Harmonics, including concepts such as 512 as being 2 times the Creator pitch is fascinating and although it requires some previous knowledge of Harmonics it is certainly a worthwhile supplemental read.

Sound Unbound and my Audio Clips
Jon Tietz's Blog for the Week
Musique Concrete
Varese Edgard's Poeme Electronique sounds like a list of individual samples just strung together. I do not hear any order in the madness. Concret PH does not seem to attempt any melody or pattern. Perhaps the most mature of the pieces listed is Pierre Schaeffer's Cinq Etudes de Bruis. Though this composition still seems to use the process of phase shifted clips there is a sense of structure, melody, and progression. I could certainly see this piece being used in a suspenseful movie scene.
But then again I haven't looked too deeply into this movement and I can't really say what its motivation really was. As a friend of mine likes to tell me, art is about the process not the product - if that was the intent here then this movement must have succeeded given we now live in a world with Kanye "Im'a let you finish" West.
Sound Unbound Chapter 1
One take away I obtained from reading the text is a firm confirmation that I would have hated majoring in English. There seems to be some obsession in expressive writing with using unnecessarily complex diction, and trying as hard as one can to bury the message of the piece. Maybe thats how literary scholars weed out the wannabes? If you can read a text and draw a single valid conclusion then you must be a literary genius. I, however, have little appreciation for this pointless weaving of an SAT verbal section into a quilt of an essay. Although....maybe its the opposite of intelligence that results in this kind of writing. Reading this chapter felt a bit like listening to Sarah Palin - you're never quite sure what word will come next, nor what context she thinks shes in. I am finding especially with musicians that there is some innate need to forgo context. I mean, of course the author believes the world exists in our heads - he describes the world as if talking to himself...why provide context or connection or explanation, he already knows what hes talking about and thats all that matters.
Communication strategies aside (despite the fact the author makes a case for everything being information while epitomizing absolutely terrible transference of said information), I was not at all convinced that this concept of sampling is anything special. In fact, I couldn't even figure out if the author was claiming it was something new and revolutionary, or something as old as dirt. First we see architecture and music related to this idea of sampling - art forms we know are very old. Then we hear about this great impact of software and the internet and FTP servers (for whatever reason that particular technology was chosen...). What was the message here? I saw no cohesion to the argument.
Further, I believe I saw an assertion early on in the chapter that this idea of sampling resulted from an exhaustion of possibilities. For example, the author mentioned a painter who stopped painting because he felt that he was just filling in the spaces. Yes, a very nice choice to try and make that point about having exhausted originality and therefore needing to compose non-original pieces to achieve originality. There is probably no better choice than someone who's life revolves around taking a white rectangle, filling it, hanging it, and finally grabbing a new white rectangle. However, lets consider the theme of mashups in our technology driven culture. The purpose in software development has nothing to do with running out of things to create, it has to do with progress. We have reached a point where the man-hour investment to move forward is prohibitively expensive in the absence of a preexisting foundation. In fact, sampling is THE MECHANISM which ENABLES original software services that the layperson considers both engaging AND original. These products are far more than the sum of their parts and in this context the samples are nothing but gears in the machine - do we consider watches to be mashups because they are made of re-usable parts (or any other machine for that matter)? I certainly don't. Once the casing is added, if that casing is sufficient to hide the influence of the parts entirely, then what you have is original.
Look at it this way - what we call "original art/creation" looking back over history consists of artifacts built on the framework of nature. Why aren't those mashups? One would probably argue, because they required human inspiration to draw art from the chaos of nature! But our revolutionary web services don't? Of course they do - our web services are built from a specific selection of technologies which come from a chaotic sea of technologies. In fact, it probably requires even greater inspiration today because nature isn't expanding exponentially - but the technology selection is. Based on this single chapter I certainly do not accept the notion that building on a man-made framework somehow makes something a mashup while the earliest art pieces are original because they were built on a natural framework.
Finally, if the theme was that all of nature is a mashup, then I must wonder why the author needed to spend so much time grinding away at this point. Of course nature is a mashup - we've had a pretty good understanding of that fundamental fact for at least 100 years, and an intuitive understanding of that fact for a couple thousand years. There are atoms, and molecules, and cells, and organs, and organisms, and ecosystems, and worlds, and galaxies, and universes. There are fundamental combinations with finite or bounded possibilities like DNA, states of electrons, particle velocities, orbital patterns, etc, etc, etc. This is neither a new truth nor a new idea - the only people who are really just now arriving at this idea of universal connection and universal information are the despicable data miners working to turn all our information, habits, and interactions into a streamlined commercialism....and I'd rather they never realized it.
So maybe it would be good for the author to worry less about the universal implications of relativity and scope the claims more to the recent history of audio and video design - because I'm really not convinced these claims hold any water past that domain.
Debussy pillage
Debussy remix by alexahenderson
I made the two beats in Ableton with MIDI drum racks, and reversed one of the beats in Audacity. I also downloaded a free midi manipulator called "SampleTank", which looked cool, but I have not installed as I do not remember the process. I also found a site which seems to have a TON OF VST plugins for Windows especially, and could be great to utilize I think: http://www.freesoundeditor.com/VSTFiltereng.htm
Soundscapes and listening assingment
Random Soundscape by lobochristian
Boat Fishing by lobochristian
Scary Movie by lobochristian
RestaurantSoundscape by lobochristian
RandomSoundscape3 by lobochristian
Also, I had the chance to listen to the 3 tracks in the Sound Unbound CD that Pat assigned:
1) Iannis Xenakis - Concrete Ph: I tried to figure out what source of audio Xenakis used in this piece but I really had no idea, especially when I looked it up. It's amazing to hear what the composers were doing back in the 50s. It looks like Xenakis is using different effects to create sounds in this track. Truly innovative for his time and something we still see in today's music.
2) Edgard Varèse - Poème Électronique: This track is a collection of sounds mixed together. I can hear some instruments and vocals. Just like the previous track, all of these sounds seem to be altered with filters and effects (echoes, fade ins, fade outs, phasers, etc). Something I found very interesting, and I'm sure it was revolutionary in its day, is the use of the sound panning.
3) Cinq Études De Bruits: Etude Violette - Pierre Schaeffer: Although this piece is a lot shorter than the other two, it is still very interesting. It sounds like Schaeffer enjoyed mixing sounds of different nature. I believe I can hear something that resembles a wind chime and maybe some rain in the background. This piece has an eerie vibe to it. Again, it can be clearly heard how Schaeffer used different techniques to modify sounds.

Sampling and the Creative Act
I found this week's readings to be quite involved. Dj. Spooky's essay on "Sampling and the Creative Act" is rife with references to other people's work and ideas and is really quite impressive as a catalog of knowledge on various topics. Miller's writing style mimics the idea he is conveying: the world is at this point a shared information culture, and that more and more ideas intersect and people understand the world in terms of the technology that surrounds us. Paul seems to be invigorated by this idea, with a sense of possibility as to what can be created and experienced by this sort of "democratization" of media, information, and the creative pursuit. I tend to take a little more pessimistic view of the path that I see civilization heading down. Though I think that there is something very profound in the idea of a shared culture and experience on a global scale, I do think that there is too much emphasis on thought and information, which is leading to more and more technology and individual expression, and less and less to nature and more lasting forms connection, which may come from activities such as meditation, quieting the mind, and simply enjoying what is.
Among one of Spooky's many references is one to David Bohm's Thought as System. Upon looking into this resource, I was interested to see that David Bohm (a quantum physicist who helped develop the first atomic bomb) actually summed up much of what I was thinking with this book (a part not implicated by Spooky). From Wikipedia:
Thought as a System
Bohm was alarmed by what he considered an increasing imbalance of not only man and nature, but among peoples, as well as people, themselves. Bohm: "So one begins to wonder what is going to happen to the human race. Technology keeps on advancing with greater and greater power, either for good or for destruction." He goes on to ask:
What is the source of all this trouble? I'm saying that the source is basically in thought. Many people would think that such a statement is crazy, because thought is the one thing we have with which to solve our problems. That's part of our tradition. Yet it looks as if the thing we use to solve our problems with is the source of our problems. It's like going to the doctor and having him make you ill. In fact, in 20% of medical cases we do apparently have that going on. But in the case of thought, it's far over 20%.
Kooyanisqatsi
I tried to focus most of my attention on the music composition of Phillip Glass. He has an amazing ability to engage the viewer and complement each of the images shown. In the beginning, soothing and slow pieces go hand in hand with beautiful landscapes, waterfalls, mountains, and clouds. As the movie progresses, and the human aspect is introduced, the music starts accelerating and increasing in power. Almost at the end of the film, the director portrays men as machines. It almost seems that the point he was trying to get across is to show men performing mundane tasks without thinking in a world where technology has taken over. Phillip Glass' music at this point has a march feel to it, hectic but steady.
At the end, it is impossible not to think about the effects man has had on earth and raises the questions about harmony between nature and mankind. The last scenes are a bit dark: pollution, city riots, beggars, and a space rocket exploding. These images leave you in a profound state of thought.
Kooyanisqatsi reminded me of another movie I've seen called Baraka. I did a little more research on both movies and it turns out the cinematographer for Kooyanisqatsi is the director for Baraka. According to Wikipedia, both movies are often compared. I suggest Baraka to anyone who enjoyed Kooyanisqatsi.

How Techno Music Is Made
Ravel's Bolero
Wikipedia has an interesting subsection on the structure of the song where it shows how the composition is played and the order of instruments.
I truly enjoy listening to this song especially how it slowly builds up from a single snare to an epic finale involving the whole orchestra.

Koyaanisqatsi for Free, and Legal on YouTube
http://www.youtube.com/watch?v=Sps6C9u7ras
Looks pretty good, but I'd still rather see it on a DVD as it is closer to how it was meant to be seen (dark theater with large screen). Oh and also without interruptions, this one has five commercial breaks. Nonetheless, very useful! Enjoy!

Ambient Music / John Cage
In class it was mentioned that this piece was designed to also be something that can be easily interrupted, and continue playing without the abruptness of inserting a pause in the middle of a pop song, and the sudden change in tempo between the announcer talking and the song. I tried this myself using the YouTube clip that was played in class, and noticed how certain this is. While a straight cut (clicking on a different point in the timeline of the clip) doesn't work when it occurs just after a new note is played, it never fails when the clip starts playing again regardless of where I start from. In fact, the music falls to the background so easily, that if instead of going back to where the first cut was, going ahead to another portion would most likely go unnoticed by people in airports. The abruptness of the initial cut (from music to interruption) can easily be diffused by having a one second fade or a crossfade into the tone that signals that a message is about to be announced.
Eno also designed the Windows startup sound for Windows 95. Here's a video that has all the windows startup sounds up to 7, and in my opinion, the best ones are Windows 95 and 98, surprisingly enough, the Vista/7 sound sounds very uninspired.
Somewhere where I read about minimalism John Cage came up, so I read about him and realized he was the composer of 4'33". I didn't know the name of it at the time, but had heard from many teachers and professors about a composer whose composition consisted of the performing sitting at a piano and not playing, but rather that the "music" or sound of the performance was that made by people as they shuffled in their chairs, coughed, or talked as time went by and the performer "didn't do anything." I realized "ohh this is the guy," and after reading about him I'm not surprised it is so.
Going off that type of composition (which he revisted twice as 0'00"/4'33" #2 and in One³), comes a link between him and ambient music. 4'33" pretty much presented ambient sounds to an audience, its own ambient sounds that its members would produce under such circumstances. As in Brian Eno's Music for Airports, where it's designed for it not have any active listeners, Cage's 4'33" has the opposite, extremely seeking listeners, at least on that first performace, evidenced by the fact that some people left the theater. Ironically at the same time, these first listeners were also extremely passive, as in their search for music or the hint of any musical sound, most, or at least the ones that left, were completely passive to the ambient sounds of the hall, the coughs and shuffles, making 4'33" an ambient composition.
Not a post about Just Intonation
When Pat first mentioned John Cage, what immediately came to mind for me was the altered piano. I must admit, the fist time I ever heard the altered piano, I was a little put off. I didn't know what to think. I laughed a little, strained my ears a little and just thought, "well maybe if I listen again..." For those of you who don't know what an altered (or prepared, if you'd rather) piano is, it is a piano that has had objects like erasers, forks, etc. put on and between specific strings inside a piano. This gives the strings altered sounds when they are struck, which allows for an all new alternative kind of music, which is exactly what I first heard from John Cage. If you're going to look up any pieces like this, I would suggest Sonatas and Interludes for Prepared Piano, Sonata No. 2. If you google that exactly, it should pull up in the video links.
Something else I would like to talk about is ambient music. When I heard Music for Airports I thought "huh... so this is ambient music." Then I remembered a couple pieces that I have written and thought "well now I know what to label them as." Ambient music is not something I think I would go out of my way to listen to, but I will agree that it probably wouldn't ever really get on my nerves. It really is a background sort of thing that you hardly notice, but when you do notice it, it's not because it bothers you.
Anyway, I guess I'll leave off there for now. See you all tomorrow.

Just Intonation Afterthoughts
Unusual Scale Similarity
Opinion on Steve Reich
My opinion started changing a bit when I searched for "Violin Phase" and "Drumming". In the text he talks about stepping away from technology for a bit and do something more instrumental so it could be played live. So I searched for live performances of these two songs. Then, my mind was blown away. Not necessarily by the content of the work but by the skilled musicians who actually play it. I am not trained in music, the little I know I've learned on my own, but I understand enough to know that playing this and this takes a lot of focus and training. To purposely move around the beat in phase then out of phase is amazing. So, I think I understand Reich's work better now.
I appreciated more of his late work, like Alexa mentioned. "Different Trains" and "City Life" is much more complex and I find it a little more pleasing. It was very interesting to learn about Steve Reich and knowing the importance he's had on music history.
Steve Reich - It's Gonna Rain - Part 1
Uploaded by inlandempires. - See the latest featured music videos.
I am trying to approach the music from the idea that what Reich was doing with taped sound- working with phase shifting and creating beats and "textured" compositions out of new repetitious materials using new technology (tape recordings)- had never been done before in 1965. Then I can appreciate the work a little more fully.
His 1988 piece, "Different Trains", which won him a Grammy, is more "mature" in it's artistic expression, which makes sense, as he would have been working for over 20 years at this point as a musician. The piece interweaves tape recordings of Holocaust survivors, people talking about train routes in America, taped recordings of trains, as well as music he wrote for violin and cello, to create another novel listening experience. I did like this better, as there seems to be a little more of a point, or "motivation" for the work than just the novelty of phase recording. Though the beginning sounds are in a key that sounds more foreboding, after the first third, the piece turns to more of a hopeful, upbeat tone for most of the song. It is interesting to hear what can be done with largely repetitious musical phrasing.

Just Intonation vs. Equal Tuning
Thursday, January 13, 2011
Intro and other things...
My name is Christian Lobo and I'm a Masters student in Mechanical Engineering. I was born and raised in Caracas, Venezuela. I am very passionate about music and sounds and I'm very excited to be taking this class.
I'm not really sure if I can add much more to what has been said about harmonics. I tried looking up some videos that would show this phenomena and I'm came across this one. It's interesting to see how the nodes and overall shape increases in complexity as the frequency goes up. Also, this video shows the importance of the harmonics into identifying a known sound to us. I wonder how other things would sound if we take some harmonics out.
For the soundscape assignment, I created a random one which ended up being pretty cool and a fishing themed.
One last thing I came across a while ago and something I might be interesting in doing as a project in this class. It's almost unbelievable how you can manipulate and modify sounds to make them whatever you want given the right equipment.

Harmonic Series and Freesound mix
http://soundcloud.com/bpokorny1/audio-design-1
One description that I read about the harmonic series said this:
"The Harmonic Series
If a listener concentrates well while hearing a single, sustained pitch (or looks at the sound waves of the pitch on an oscilloscope) the listener hears not only the strong tone of the pitch but also higher and softer pitches above the more noticeable lower tone. These additional higher and fainter pitches that occur above the stronger and lower pitch are produced by the vibrating object. Because they are softer than the lower tone they are much harder to hear. A listener must concentrate intensely to be aware of these acoustical phenomena; however, they are seen quite easily on an oscilloscope."
I don't really know if this is pertinent to the harmonic series, but when looking at this description, I couldn't help but think about octave pedals. I don't know how many of you are into guitar, but an octave pedal allows you to play any tone from several octaves at a time. It's something that, like a harmonic series, is rather tough to notice, but really offers a cool tone if you happen to be listening for it.
Blog Assignments
It is now 12:08 and several of you have not blogged on the Harmonic series as requested and will not get full points on the assignment. I will explain in depth and give you options on what you may choose to blog on each week, but i expect that you blog prior to the class day so i may read them and we all may comment and communicate with each other during the week.
If you have NOT blogged on the harmonic series YET, please do so but realise everything AFTER this post is essentially LATE and will not receive full credit.

Fundamental Frequencies and Harmonic Series
I'm Andres, Film and Media Studies major and Mass Communications minor, looking to graduate next fall. I have a pretty sound/music intensive project I'm currently working on and I'm looking forward to this class as it will probably be of great help.
A friend of mine that is music inclined once explained to me the harmonic series, I just didn't realize it was what we were talking about in class. But to get there I should first discuss what I've found on fundamental frequency. In plainest terms, the fundamental frequency is the lowest frequency at which an object vibrates freely. This is one of the definitions I found, but mostly applies to just physics. In music however, this is incomplete. A fundamental frequency is the lowest frequency of a periodic waveform. If I'm correct, periodic waveforms in sound are sustained sounds without varying pitch, although their frequency may be low enough that you can hear the variations in wavelength. Because the wave is periodic, meaning it repeats exactly the same, one period alone of the wave serves to describe the entire wave. This period is thus known as the fundamental period, and the lowest frequency for which this smooth repetition remains true is the fundamental frequency. The fundamental frequency is also the first harmonic.
The harmonic series then is the series of sounds produced when the frequency is increased by adding the initial frequency repeatedly. For example if the frequency of the fundamental is 50 Hz, the second harmonic would be 100 Hz, the third 150 Hz, etc. The harmonic series is related by whole number ratios, and like stated before, have periodic waveforms. When these are played in conjunction to each other, they sound very smooth and pleasant, whereas other notes whose frequency does not fall in the harmonic frequency, have irregular and/or non-repeating wavelengths, and thus don't sound nearly as pleasant. This is because all the tones on a harmonic series are related by whole number ratios; same wave with increased frequency by two times, three times, four times, etc.
I have heard this being played in a piano, going up a harmonic series from C to C to G... etc, and with dissonant keys not from the series thrown in to clarify the point.
On another note I found this video on YouTube about an iPod application that may help on the understanding of periodic waves.

Introduction
Tuesday, January 11, 2011
Harmonics
An integer of something means simply that if the fundamental frequency is 25Hz, that 2 x 25Hz, 3 x 25Hz and so on, would produce the harmonics for that particular wave. Conversely, if a wave is oscillating at partials/frequencies that are not integers of each other, the sound is referred to as inharmonic and not so pleasing to the novice ear.
The way that our ear discerns the different styles of sound or timbre (ie: the difference between the flute and the clarinet playing the same note), is the result of the relative strengths of each individual frequency making up the sound.
