PSS. I noticed you are using Vista - welcome to the "club"
Actually, I have 2 main machines which run Vista Ultimate x64, Windows 7 Home premium x64, Windows 7 Ultimate x64 and ubuntu 10.04TLS (you guessed it) x64... Vista isn't always the greatest boat to be in, so I'm glad I have dual-boot setups. Sometimes, a nice plain linux distro is so refreshing if you know what I mean...

Also, as for the music, I think a lot of wav samples on different frequencies might be of use, and you actually play the music; as in you hit a note and it plays a drone and you have to hit as many of the notes scrolling past as you can to hear a more complete song.

Its not final yet, but I'm working on it.

cheers,
