Changelog

The app is now available for iPhone on the App Store, alongside Android on Google Play — the same melodies and harmonizations on every device.

A redesigned plans page with a live circle, yearly pricing by default and a 19-point comparison. Founding Launch seats are limited and counted down live.

Open the mobile version straight in the browser, add it to your home screen and sign in with Google, Apple, Facebook or GitHub — no download required.

The whole site now speaks 12 languages. On your first visit we follow the language of your phone or browser, and your manual choice always wins.

Harmonization now costs you one session instead of charging every single change, so you can try, undo and refine without watching the counter.

Chord names moved off the score itself, so editing a chord no longer makes the whole sheet blink. The chord deck also follows the line you are editing.

Write a melody, harmonize it and listen back right on your phone. The app arrived on Google Play in July and speaks all 12 languages from day one.

A full-screen metronome with four sounds, a tuner built on our circle, and a Sing mode that records your voice and plays it over the notes.

Every piece you save lives in your library, with a bin you can restore from. Publish to the gallery to be heard, share a link or download MIDI and MusicXML.

Record from your keyboard over a playing piece, keep several takes, stack layers with a small mixer, or lock the input to rehearse without recording.

Sheets print with a proper header and respect your zoom and spacing. Lyrics, pedal, fermata, hairpins, ottava, tremolo, trill and arpeggio are now written in.

Browsing variants is free, and credits are charged by the bars you actually rework. A new history page shows every charge, and packs can be topped up any time.

A dedicated place to turn a melody into a piece, opening in three depths — Sketch, Harmony and Workshop. Your work saves itself and comes back after a reload.

Pick chords from the palette below and drop them into any bar. Suggestions appear as your melody grows, and a double click rotates a chord to its next voicing.

A seven-octave piano and a 24-fret guitar or violin float above your score, resize freely and remember where you left them. Bass and Solo can move to another monitor.

Get a walking bass with inversions and approach notes, plus a bebop or pentatonic solo line. As a set, both parts follow the sections of your piece.

A new instrument built on our circle: note buttons around it, a duration palette, tonic-subdominant-dominant zones on a joystick, and a ring to move between bars.

A cleaner transport bar with undo and redo, playback from the note you are editing, MIDI recording in the header, and studio-style shortcuts with help on F1.

Enter notes step by step or record in real time with a count-in. Chords are recognized as you release the keys, the sustain pedal and hand split work as expected.

Lights above the keys show the notes of the current scale or chord, following either the circle or the playing score, with your own split between left and right hand.

Apply on your own, get a personal link and a dashboard with clicks, referred musicians and commissions that grow from 25 to 30 percent.

A full-screen builder with six ready designs — from songwriter to jazz and kids teacher — live preview, a short guided tour and automatic translation of your texts.

Create a class, let students join with a code, and follow how the group is doing in one place.

Adjust sheet size and spacing, set volume and tempo with knobs, switch to a running-line view, or open a ready piece from the demo library.
