I missed class on Thursday but I still researched about granular synthesis and played with Cecilia and made these samples:
Afterwards, my cecilia unfortunately kept crashing and unfortunately I could not record anymore.

Granular synthesis is denoted because of the microsounds called grains that are splits of 50 ms to 1 s samples that are layered on top of each other and edited around different parameters such as speed, volume, and frequency. The micro sounds does not fit on a normal time scale. The waveform, spatial position, density, and envelope allow the many different variety of sounds to be produced. Riverrun is known as the most versatile real time granular synthesizer today written by Barry Truax and he has written other pieces as well. Iannis Xekanis was the first inventor of this synthesis technique, being the first one to explain compositional theory with grains of sound. He said, "All sound, even continuous musical variation, is conceived as an assemblage of a large number of elementary sounds adequately disposed in time. In the attack, body, and decline of a complex sound, thousands of pure sounds appear in a more or less short interval of time." (1959)
Curtis Roads is also a author, composer, and computer programmer specializing in granular and pulsar synthesis. Here is a video I found helpful of Curtis Roads himself explaining the mechanism.

Noise music:
Noise music is music that contains multiple genres of composition that are in the categories of noise and music. Generally it contains aspects of improvisation, extended technique, cacophony, indeterminacy along with conventional use of melody, harmony, and rhythm. Jimi Hendrix is a domain example with his use of feedback. Throbbing Gristle, Psychic TV, and Keiji Haino, and Tony Conrad are all examples of noise music. Here is a live performance of Throbbing Gristle that perfectly defines the noise music elements and the synthesis of them.
