I made my first tiny web tool because I wanted practice, not ads
I have been learning to read sheet music, and I kept running into the same problem: the practice apps were close to what I wanted, but not quite mine.
Some are polished, but full of interruptions. Some are useful, but locked into a training path that does not match the way I want to learn. I wanted something I could open quickly, use for a few focused minutes, and reshape whenever the practice felt wrong.
So I built a small browser tool for myself. It shows a note on the staff, and I tap the matching piano key. There is an easy mode for calm repetition and a progressive mode that grows into bass clef, accidentals, intervals, and chords. It also cares about speed, because recognizing a note correctly after ten seconds is not the same as really knowing it.
The reason I want to keep building tools is simple: software can make a learning environment less generic. When the keyboard feels wrong on mobile, I can fix it. When labels make practice too easy, I can remove them. When I want accidentals before chords, I can change the order.
This site is where I will keep a public trail of those experiments: what I built, why I built it, what broke, and what I want to improve next.
