Mood
Swings
by Steven Biederman
This is a composition change, in many of its forms, from good to bad, and from
bad to good.
Originally I was planning on sampling a guitar, but after playing around with some of the effects I decided that I could create same amazing sounds using just the tools in the system itself. In the end I did end up sampling a bass guitar which is the file bass.wav. I also sampled a cheap sounding bass drum called C_kick.wav.
I used a cool delay effect on the drum and raised the pitch a large amount. I found a terrain synthesis function which is used at the beginning of the song. This was used to represent stress. After that I used a pluck function to give the impression of pleasantness. A granular synthesis comes in after to give an eerier feeling. It slowly transits back into pleasantness before ending in an eerier stress. I used 2 to granular synthesizers. One had a random max pitch. And the other had a random max pitch and grain density.
Here is a data flow diagram of instrument 4:
