Amazing little trombone!
Ive actually used this app for several years now and it has continued to hold its position right on my main screen of apps.
What we really get a kick out of is the song book. Imagine guitar hero but for a trombone. The app tells you where you should be tapping and when to play a song. This is a riot when you get a group together and everyone tries to keep up with one of the faster and more difficult songs!
This app is what it would look like if Apple themselves added a trombone to garage band. It has that level of polish.
