ABSTRACT:
A wind instrument is provided with electronic tubing control. The wind instrument has at least a pair of an acoustic sensor and an acoustic actuator in a straight pipe portion of a wind instrument and an electronic control for supplying a delayed output of the acoustic sensor to the actuator to electronically control a change in pressure in a pipe by variably changing the delay amount in correspondence with a performance of the instrument thereby electronically changing the pitch of a produced musical tone.
