## What is DoSo Keys?

DoSo Keys is a piano for your pocket – to play, listen and explore.

Play notes, chords and melodies on a keyboard that adapts to your device: in portrait you play one octave with large keys, in landscape and on iPad several octaves. Use the arrows to move the visible range between C1 and C8.

• Play chords with several fingers
• Slide across the keys for glissandi
• Releasing a key damps the note – just like a piano
• See the name of every note, with both spellings for black keys, e.g. C# / Db (C sharp / D flat)
• Plays even with the silent switch on, for example in choir rehearsal
• Works fully offline

No account, no ads, no tracking, no in-app purchases. DoSo Keys collects no data.
