All week long I have been playing around with Smule's Leaf Trombone on my iPhone, a fully interactive trombone! It's a lot of fun learning how to play classic songs like Stand by Me and Hallelujah; and after one masters a particular song they can perform it on the World Stage and be judged by their peers. With Smule's Leaf Trombone World Stage you can be an artist and a judge; having that ability is what makes Leaf Trombone so amazing.
If the Ocarina was fun let me just tell you from experience that Smule Did it Again with Leaf Trombone. Smule's applications make the world just a little bit smaller and a little bit better. The kicker for me was the fact that you can write your own songs and (or) convert your favorite songs to be played on the Leaf Trombone.
Playing Leaf Trombone is easy: blow into your iPhone's microphone (or, in Touch mode, simply touch the screen) and press down on the leaf to play a note. Slide your finger towards you - you'll hear the pitch get higher, just like a real trombone.
