Brilliant Concept – iBone - the Pocket Trombone Review

I've played Trombone for 20 years and this app is amazing. I would recommend this a MUST have for any novice trombone player. If you learned trombone by memorizing positions that your teacher wrote for you on the music, this is the app for you!
