Abstract
Among other things, a tuning device is used with a musical wind instrument. The tuning device includes a linear actuator, a first mounting assembly attached to the linear actuator and adapted for releasable mounting to the first portion of the musical wind instrument to be tuned, a second mounting assembly attached to the linear actuator and adapted for releasable mounting to the second portion of the musical wind instrument to be tuned, a sensor for a frequency of a note played on the musical wind instrument, a comparator of the played frequency to a reference frequency, and a transmitter for issuing a movement signal to the linear actuator for changing spacing between the first and second mounting assemblies to adjust relationship between first and second tubular portions, and for ceasing the movement signal when the comparator determines that the played frequency has approximately matched the reference frequency.
