Sound Categories
These are some of the various categories we came up with in class, the idea being
to use these as aspects to consider when making graphs of
Edgard Varese's Poem Electronique.
Hopefully, in the not-too-distant future we'll be getting a firmer grasp on how
to describe technically some of the different sounds we hear.
- Basic Types
- Voice
- Percussive
- Electronically Generated
- Natural (Acoustic)
- Glissando (ie. a continuous rise or descent of pitch)
- Simulation / Synthesized
- Envelopes
- Sustained ('Longish' Sounds)
- Very Short
- "Looped" (Repeated Sounds)
- Frequency
- High, Low, etc.
- Glissando
- Static
- Chord
- Amplitude
- Loud, Soft, etc.
- Decreasing and Increasing Amplitude Envelopes
- Sudden Changes in Amplitude
- Timbre
- Harmonic/Inharmonic
- Bright/Dull (ie. number and amplitude of partials)
- Natural/Electronic (ie. static or dynamic spectra)
- Space/Location
- Left, Right, Center...
- Quad
- Moving Sound (panning)
- Reverberation (perceived distance from source, room size...)
