Piano Macaroni: Piano Chords

Piano Macaroni is a beautifully simple piano you can carry anywhere — no login, no ads, no internet required.

PLAY INSTANTLY
Tap a key and the note plays. Slide across keys to glissando. Press chords with multi-touch. Notes ring with a warm, harmonic piano tone shaped by a fast-attack, slow-release envelope so every press feels real.

SEE WHAT YOU PLAY — FREE
Every key you hold shows up in large, clear letters above the keyboard. Hold three or more and Piano Macaroni names the chord for you, from plain triads through Cmaj9, 13ths and altered dominants. Five chord names a day are free, every day, with no account and no trial.

PREMIUM UNLOCK ($0.99 one-time)
The free tier gives you a clean, single-octave piano and daily chord names. A one-time $0.99 unlock adds:

• Up to 5 octaves on screen — pick how many you want.
• Octave shift — move the visible window up or down.
• 5 instrument voices — Grand Piano, Electric Piano, Bright Piano, Organ, Synth Pad.
• Velocity-sensitive touch — softer touches play softer, firm touches swell.
