Launch tomorrow and you could get a YC interview

If you re still sitting on your launch, this is the push.

YC made a special exception for this community: one or more companies that launch tomorrow will get a YC interview and potentially funding. A YC partner will review every eligible launch.

Making the invisible visible

hey everyone

I made this after being inspired by Bret Victor's making the invisible, visible. I have never been able to study music theory as it is, so I made something that I hope will help others learn music theory. The visual spatial among us!
