Someone made a tiny piano app for the MacBook Touch Bar

The Touch Bar on the new MacBook Pro is either the best feature to come to the laptop in years or the most gimmicky, depending on where you stand. (Glowing reviews aside, I stand by my assessment that it looks like an ergonomic nightmare.)

But that hasn't stopped creative developers from finding new uses for the Touch Bar. Now, one developer has made a new music app that turns the Touch Bar into what might be the world's tiniest piano.

Called Touch Bar Piano, the free app turns the Touch Bar into a tiny, but fully playable, piano. It's even possible to pick out individual keys well enough to play a song.

If piano isn't your thing, the app includes 127 other instruments, including stringed instruments and choir sounds.

Check it out in action in the video below.

Unfortunately, the app is more of a "toy" for now, says developer Graham Parks, so you can't record what you play or do much else. But Parks says he's open to doing more with the app that he says he "hacked together" in a couple hours.

"If there's interest, I'd love to make it interface with other music apps as a controller," Parks wrote in an email to Mashable.

You can check out the app on Parks' website. If you don't have a new MacBook Pro with Touch Bar, though, you're out of luck.

"It does nothing useful on other Macs," according to Parks.
