The tunes programmed on each TinyPiano are randomly selected from a set of 200 tones during the manufacturing process. Most examples of TinyPiano are unique! ASSEMBLY There’s no soldering, programming, or glue required to assemble the TinyPiano. All you need is the package, the parts in it, and about two minutes before you can compose a tiny tune with your TinyPiano!
