When the iPhone App Store launched last year, a flood of 'virtual' music apps, ranging from pianos to drums hit the market. Most of these didn't fare so well on the iPhone's small screen, save for one fantastic standout: Smule's Ocarina, which was perfectly suited for the iPhone and was fairly easy for beginners to pick up. The app became a massive success, and became one of the App Store's most popular applications ever. Today, Smule has released Leaf Trombone: World Stage, a new virtual musical instrument that is better than Ocarina in nearly every way.
One of the biggest issues newbies had with Ocarina was that there was no musical instruction built in - users would have to visit Smule's website, where they could download 'tabs' of their favorite songs. Without the tabs, playing familiar tunes became an exercise in frustration, and I suspect many users never made it to the website and simply tried to do the best they could on their own.
