The exercises are fun (and easy for now, but I'm only on stage 3)!
I must say I was briefly surprised at how disorienting it is to see a graphic of a keyboard from A3 to A4. When you don't see the set of 3 black keys consecutively and instead see what looks like 2 sets of 2 black keys, it really takes a second to orient yourself!
It would be good if it used interval names rather than relying on absolute notes. Eg minor third, fifth etc. Also notes played together and more and more complex chords as level gets higher. keyboard shortcuts would be great too. And a fully hands-free mode with voice input for practise while doing other things.
I did not write a single line character of code directly, everything was by instructing Claude Code.
I’ve been building something in this space as well, but with a broader toolkit [1] approach rather than a single-purpose interval trainer. The thing to me that's a bit jarring is the keyboard itself. Also, when it comes to ear-training (and while I've included this as well), without context it's not quite as useful. It's an area I plan to revise and really work on, but want to find a better approach. Good luck.
am i the only one who find the a-a part of the keyboard an odd choice of keyboard?
MusicTheory's interval ear training app is free and has a bunch of extra options: https://www.musictheory.net/exercises/ear-interval
I was also initially confused by the scale A3 to A4 until I realized that the musical interval trainer starts you on "A Minor Pentatonic". This might be a bit confusing for non-musicians so I'd suggest starting with a more standard C Major scale and a set of easy intervals (perfect 4th, perfect 5th, octave, etc) or even a quick question to allow a user to indicate their musical familiarity.
