Tinkle Tinkle Little Keys

Look, the piano thingy shows you chords as smol, two-octave baby keyboards. The keys you're supposed to actually play? They're lit up in angry red so you can't miss 'em (you're welcome).

Inversions? ZOMG, they're just what happens when you flip the chord around & don't start with the root note like a normal person. So the app makes one inversion for each note in your chord. Wanna see it in action? Standard major triad = three different ways to mess it up. Get yourself a gnarly complex chord & boom—suddenly you've got like a million inversions. Fun times! 🎹
