Most MacBook Pro apps that have implemented support for the new Touch Bar have focused on putting settings, editing tools, and other utilitarian features right at a user's fingertips, but a new app from developer Graham Parks aims to have a little more fun with it, MacRumors said.

The "Touch Bar Piano" app is designed to turn the Touch Bar on the MacBook Pro into a little tiny touch-based piano that can be used to make music.

Available on Parks' website, Touch Bar Piano is fully polyphonic and offers 128 instruments to play with. It only works with the MacBook Pro with Touch Bar, but Touch Bar emulator Touché can be used to try it out if you don't have one of Apple's latest MacBook Pros.

Touch Bar Piano doesn't exactly follow Apple's developer guidelines, which say the Touch Bar should be used as an extension of the keyboard and the trackpad rather than a display, but it's a fun way to show off what the new MacBook Pro can do.
