Cello App Cello Finger Chart & Graded Lessons

Soloist Cello grades every note you play on-device — no ads, no account, and audio never leaves your iPhone.

The cello, in bass clef, heard honestly.

Your playing never leaves your device: listening, transcription, and grading run on-device. No account, no ads, no trackers.

A premium instrument deserves more than a metronome. Soloist Cello brings pitch-true grading down into bass clef and the cello's register, with sampled tone and verified repertoire.

Bass-clef notation & register shift

Notation and grading built for the cello's range, not a transposed violin.

Honest intonation feedback

Per-note pitch and timing from your device's mic.

Verified masterworks

Score-accurate melodies with authored bowings.

How honest grading works

Listen.
Play your take and Soloist Cello captures it through the microphone, processing everything on your device. Audio is never uploaded — our backend has no audio endpoints at all.
Measure.
The engine locates each note and hears whether it drifted sharp or flat — the feedback a fretless instrument demands — comparing pitch, timing, and onset against the score.
Report.
You see which notes rang true, which didn't, and what to loop next — drills built from your actual rough spots. An unclear take is left ungraded, never turned into a confident mistake.

Real screens. Real practice.
