- harmonic series on strings (interact here)
- levels of energy at different harmonics impact timbre (interact here)
- different synthesis methods based on this (+ physical modeling)

Another approach: sampling. Record a sample, play it back. Change pitch, play backwards, add envelope, filter, etc.
Hardware samplers. Software samplers. Examples on Ableton Live:
- Simpler: record whistle; play instrument samples.
- Sampler: more sophisticated controls.
Example use in performance: Edge of the Universe Project.
