About PineTone
PineTone is a free, playable browser simulation of the isomorphic cylinder keyboard made by Mosi Audio. Explore music with your computer keyboard, mouse or touchscreen. No account is needed to play.
A shape you can carry to every key
On an isomorphic keyboard, the same musical interval always has the same relationship on the grid. A chord keeps its shape when you move it to another key. PineTone makes that relationship visible with numbered scale degrees, optional note names, scale highlights and chord shapes. Change the key to hear and see the same pattern elsewhere.
Explore, practise and see your progress
The Grove is the place to play freely, try scales, hear chords and explore progressions. The Trail brings songs beside the instrument in number notation, with listening and practice controls. Import a MusicXML or MIDI score to work on your own music, or open the sheet view and use the browser's print dialog to save it as a PDF. Your Rings show the notes you have played, streaks, milestones and discoveries.
Getting started
Open the keyboard in a browser with JavaScript and audio enabled. Tap or click a key to start sound, or use the computer-key labels shown on the grid. In the Grove, choose a scale and press a chord button to see and hear its shape. Use the key stepper in the header to transpose; the same chord shape works in every key. The help button explains the keyboard shortcuts and how to move the cylinder.
Choose Trail, then use the song title to open the song picker. Select a built-in song or use Import score for a MusicXML (.musicxml, .xml or .mxl) or MIDI (.mid or .midi) file. Use Listen to hear the song and Practice to play along. Open Sheet to view the notation and use Save as PDF to open the browser's print dialog. PineTone needs a browser for interactive playing and does not publish a supported automation API.
Play on your own terms
Progress, settings and imported scores are kept in your browser. Optional sign-in lets them follow you between devices. You can download a backup from Settings. The privacy page explains storage, accounts and service reports in detail. The simulator is a learning and exploration tool; its feel and behaviour may differ from the physical instrument.
