These vibrations are picked up by the Transmitter, and wirelessly transmitted to the Tuner. However, depending where the Transmitter is attached to the instrument, the vibrations may not be picked up very well. In this case, try repostioning the Transmitter to pick up these vibrations better. The Transmitter can be attached to musical instruments such as woodwind, brass or strings instruments. With some musical instruments, such as a saxophone, you can attach the Transmitter to a strap or other part that vibrates, rather than directly to the instrument itself.
