Traditional Music Instruments / Construction
Most acoustic instruments consist of
an excitation source that can oscillate in different
ways under the control of the performer
a resonating system that couples the vibrations of
the oscillator to the surrounding air
Parts of the performer’s body generate the energy for
the excitation of the instrument, interacting through
the instrument’s control interface
