Now anyone can create music and beats completely from scratch and right in their browser, by simulating almost 50 different instruments, ranging from common instruments like various drums, pianos and guitars to orchestral instruments like harps and flutes to more obscure (but fun!) instruments you may never have heard of like the balarimba and hammered dulcimer.

There are tons of different instruments to chose from.
Creation is really simple and every creation can be exported both as mp3 and to be used in the Aviary Audio Editor.
