Real-time fingerings for 19 instruments — bouzouki, concertina, uilleann pipes, bagpipes and more. Automatic chords, tune recognition, cross-device sync, in 11 languages. 100% offline, no account required.
Since the summer, Little Session has learned to listen better, to speak your language and to follow you from one device to the next.
The recognition engine has been rebuilt: each tune's key signature is honoured, the melody is followed even with accompaniment, hornpipes and swing are tolerated. Right answer on top in 64% of tested clips (40% before), an answer in under a second — and an honest verdict: green only when it's sure.
DownloadThe whole app — screens, help, settings — now speaks eleven languages: English, French, Dutch, German, Spanish, Italian, Portuguese, Swedish, Danish, Japanese and Korean. It follows your phone's language automatically, and can be changed in the settings.
DownloadRepertoire, sets, tags and settings follow you from phone to tablet to PC. End-to-end encrypted: the server never sees your data in the clear, and one pairing code is all it takes to add a device. Premium feature.
DownloadA reel then a jig in the same project, each at its own tempo and meter. The accompaniment swings with the melody, the bodhrán phrases, piano, accordion and harp answer. Each take is realigned by ear right after recording; M4A and MIDI export, project sharing with the community.
DownloadAccompaniment on every instrument, a tag-organised repertoire, creation mode and a tuner: Little Session is your complete session companion.

Diagrams follow the score under every chord name — and not just for fretted instruments: uilleann regulators and diatonic accordion basses sit on the score exactly like a DADGAD guitar or bouzouki grid. Bass-clef piano, Stradella, B/C, C#/D… Tap a diagram to edit the shape and hear the result.

The complete TheSession.org database, built-in and searchable offline. Reels, jigs, hornpipes, polkas, slides, slip jigs, waltzes and more.
Every tune is rendered as sheet music from ABC notation. Chords are automatically annotated, and the fingering diagram for your instrument follows the melody note by note.
On any existing tune, tap a measure to open the editor. Change the suggested chord, add ornaments, fine-tune notes. (To compose a tune from scratch, see Creation Mode.)
Pick your instrument from 4 families: winds, strings, keyboards and reeds. Each instrument has its own interactive fingering diagram, true to the real thing.
Group your tunes into sets, just like in a session. Tag them, adjust repeats, and start playback with one tap.
Play a full set: tunes flow automatically one after another. The strip at the top shows your position, and a floating panel previews the next tune so you're never caught off guard.
Whatever your instrument, fingerings are displayed note by note during playback, with the current note highlighted on the sheet music.
