This is a pre-made Arduino shield/kit, with enough pushbuttons to play two octaves ($50). The following components are built-in:

The first image in this article shows an array of 13 pushbuttons connected to the 13 digital pins of the Arduino, which is just enough for playing a full octave of notes.
Further down in the blog post is a video showing a completed enclosure with 4 pots controlling various effects, similar to the pre-made kit above.

This one is the most modest: Two printed strips of paper covered with inkjet ink are layered on top of each other. When contact is made between the two strips, it creates varying levels of resistance. The Arduino then generates discrete tones thru a connected speaker based on the level of voltage read.
