TuneIt!

If you are a musician or just want to tune some instrument, you'll want to use this tool. It has a tone scale (you can choose frequency of the A) and a metronome. Send me new ideas about what to include in this program. Download TuneIt-0.03.zip!

"...As a guitarist, I needed something small and simple that would both produce tuning tones and demonstrate a particular tempo. TuneIt fulfills both needs admirably, and is even flexible enough to allow the base pitch to be altered from the concert standard of 440Hz - essential when playing with some older instruments. Each tuning tone sounds continuously until stopped, a tap-saving feature that's a real boon when trying to juggle a guitar and Palm at the same time."
