A BETTER version of Pachelbel's Canon (than my older one). If you click Advanced Options you can change tempo, key, and skip through the piece. Press space to start it. Use TURBO MODE is optional. You can play it backwards too. Really, what the computer can do is amazing. Seriously, like the mini piano PLAYS it! Put your mouse over the 'Pachelbel's Canon' part in blue and you'll get even more English to read!
I like it in Ab the most. That's -6 on the transposer thingy. I don't know how to play this exact variation of it (I just mashed together bits and pieces in makingf this) but I can play Pachelbel's Canon smoothly in D, C, Bb, Ab. I look forward to learning it in every key.
