Pitch 1024

Pitch 1024 hands you a reference pitch sung by a real musician, not a synthesized beep. Ask Claude for a note, a chord sung by several voices, starting pitches for any key, or a chord progression, and tap the card to hear it in the voice of the musician you choose from a cast of five.

Build a chord with several voices harmonizing together, in stereo or in full 3D around you on headphones. Pass a progression around the ensemble one singer per chord, or drill your ear with note, interval and chord-quality quizzes that keep the answer hidden until you guess, with Claude grading each answer.

Useful for singers warming up, a cappella groups finding their starting pitches, instrumentalists tuning by ear, and anyone who would rather match a real voice than a tone generator.

The voices are pre-recorded performances, embedded in the card and played on your device. No account is needed, and the app stores nothing about you. Tap the card once to turn on audio, since browsers block autoplay.
