Menlo Park, Calif.-based Smule, which was founded by Stanford computer scientists that make musical games for the iPhone, has launched its latest product today on the iTunes App Store: “Leaf Trombone World Stage.” The 99-cent application works by blowing into your iPhone microphone and sliding your finger along the touchscreen to simulate playing the Trombone.
The first time we heard about this application was at Apple’s Cupertino event in March, where it announced the iPhone 3.0 software. The game garnered far and away the most applause from the audience after Smule co-founder Dr. Ge Wang and his assistant played a duet of “Phantom of the Opera.” While the application is launching now, we imagine that it will be upgraded later this summer when Apple (NSDQ: AAPL) rolls out the software update, so that users can use the “close proximity” feature to pair multiple iPhones together to compete in multi-player mode. Prior to Leaf Trombone World Stage, Smule launched several other applications, including Ocarina, which Apple said is the 14th best-selling application of all time.
Here’s a video from the March 17 event:
