SightSing came out of a memory. I sang in college, and the expectation was that I could sight-read — that's how you kept your spot in the ensemble. So I had to get better, on my own time, between rehearsals. The problem was I had no structured way to do it. I'd open a score, hum through it, and move on with no real sense of whether the work was sticking.

For years afterward I kept thinking: if there were an app that could just listen to me while I practiced — and help me chip away at intervals, rhythms, and modal patterns level by level — I could actually get better at sight-reading over time. Five minutes a day. No guessing whether I was improving.

That's what SightSing is. The mic listens while you sing. The 18-level curriculum walks you from your first three-note solfege pattern up through complex modal melodies, syncopated rhythms, and chromatic intervals — one new concept per level, with rolling-window mastery so a bad day doesn't reset your progress.

It's built for two people: the music student just starting to sight-read (choir kid, voice major, theory class), and the experienced vocalist who wants to sharpen a skill that's atrophied. Same app, same curriculum — the level system meets you where you are.

The curriculum is built around established sight-singing pedagogy: voice-specific tessituras, rolling-window mastery (not streak resets), and a deliberate ramp that doesn't skip the boring-but-essential intervals. The goal is steady, honest progress — not gamified streaks that punish you for taking a day off.
