Essential Downloads

Finale Notepad
Finale is a pretty powerful notation program made by Coda. This notepad is a free "lite" version. If you want to do some basic writing that you can print, then this is great.

MetroMon
This is a computer based metronome and guitar tuner.

iTunes
This is Apple's music player. It is way better than Windows Media Player. It rips CDs, burns them, catalogs your music files all with great simplicity. You can also download songs for .99 each.
