Turn your iPhone/iPod Touch into a drum-like musical instrument. Thanks to the iPhone's accelerometer, it's as simple to use as a real drum stick, and brings a variety of bells, piano, guitar and bass sounds. Made for pure one-hand musical enjoyment :)
You can "beat" two "instruments" in the same time, with 5 notes/pitches on the upper, and 2 on the lower (bass) instrument. A simple demo video of playing the musical scale is available at

as well as inside the application.
Enjoy :)
