Piano 1024

Piano 1024 puts a playable synth piano in your conversation. Ask Claude for a note, a chord, a scale, a chord progression or a melody, and it appears as a card with a keyboard you can play, loop, slow to half speed, transpose, and switch between piano, electric piano and organ voices. Learn a song: ask "teach me the melody of Twinkle Twinkle Little Star" and the melody is split into phrases with a follow-along highlight, phrase-by-phrase navigation and an optional left hand you can practice hands separately. Claude explains the fingering and phrase boundaries in the chat. Write music together: describe a mood ("a sad, dreamy progression for a low alto") and keep revising it across turns ("darker", "slower", "add a melody over it"). Each card carries the full song, so every change builds on the last one. Practice: run interval, chord and scale ear-training drills that Claude grades and adapts as you improve, or start a metronome in any meter, including compound time like 6/8. All sound is synthesized on your device inside the card. No account is needed, and the app stores nothing about you. Tap the card once to turn on audio, since browsers block autoplay.
