The Instrument

The key block in this algorithm is the instrument, since it is here that the
fundamental tone or "timbre" of the sound is defined. The instrument model
consists primarily of a driver — the reed/mouthpiece, lip/mouthpiece, or
bow/string system — and a resonant system corresponding to the tube and
air column or string.
One of the remarkable features of the Virtual Acoustic Synthesis system is
that just about any driver can be used with any type of pipe or string.
NOTES
• The sound thus produced is amplified and sustained by the body of the instru-
ment.
• The pitch of the sound is determined by the length of the air column or string, and the
timbre is a complex product of the driving source (reed, lip, air, string), the shape of
the resonant cavity, the materials from which the instrument is made, etc.

In all these instruments pressure applied
here (the driving point) causes vibration
which results in sound.
