I've came across a site called "Wolfram Alpha". I think its pretty cool, just a few flaws in it.

Type in, for example, C major. It will play you the C scale on the piano. Type in any maths equation. It will answer it.

The only flaw I found was that the B minor scale was played incorrectly:

Other than that, I think its awesome.

What’s wrong with the B minor scale? That’s perfect natural B minor (aeolian scale). Or what’s your interpretation of a “correct” B minor scale? What it can’t do are the more obscure scales like mixolydian b9 or something like that.

He probably wants the 7th kicked up a half a step, I forget what that's called.
