Is there a good web app for generating tones to help tune musical instruments?

Since some of the instruments I play are a little obscure (eg. a guzheng, which has 25 strings; a charango, for which it's common to change frequently between tunings) my fantasy feature wish list would be:

  • Arbitrary pitches (eg. not limited to western scales)
  • A way to step through a sequence of an arbitrary number of tones that that correspond to a particular tuning of a specific instrument
  • Ability to save or link to such a sequence

Though I'd settle for a simple tone generator with a nice interface :)

  • I am a bit curious how you can be sure the computer will be playing the right tone? Several years ago I had a computer generating a tone that was supposed to be 1000hz a frequency counter showed it was closer to 1050hz. – Zoredache Oct 22 '10 at 6:07

This is the best I could find. You can tweak the pitches by cents, play several preset series of pitches, and save your settings, but I don't think you can create your own series of pitches.


  • thanks, that sounds better that anything I've been able to find so far, but it's giving me a 403 Forbidden error :( – Ian Mackinnon Oct 21 '10 at 23:20
  • @Ian Mackinnon: That's interesting, I just tried it again and it still works fine for me. Can you access this page? It gives some troubleshooting suggestions. Maybe try a different browser or computer and see if that makes a difference. – BenV Oct 21 '10 at 23:43
