Question:

What's a metronome??? and where can I get one?

Best Answer - Chosen by Asker: Its a device that emits clicking noises to a certain tempo. Its used to help people practice when they're alone. I use a metronome, whenever I play my sax so I stay with the beat of the music, so I can play it better, when I play with big group. You'll probaly find the best price on one at musiciansfriend.com or guitarcenter.com
