Harmonium App Honest Sur & Sargam Practice

Harmonium grades clear pitch evidence on-device and says when it could not hear you clearly — no ads, no account, and no recording upload.

Find your Sa. Hear the honest answer.

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

A responsive reed keyboard, confidence-gated pitch feedback, Find-your-Sa setup, and sargam labels in Roman, Devanagari, or Gurmukhi.

A clear take is graded; an unclear take says it could not hear you clearly.

Choose or detect a comfortable Sa and the keyboard, drone, and approved lessons repitch together.

Switch between Roman, Devanagari, and Gurmukhi sargam labels, with the choice saved.

How honest grading works

Listen.
Play your take and Harmonium: Riyaz & Sur 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 you played — its pitch, its timing, its onset — and compares it against the score, note by note.
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.

No. Low-confidence audio is left ungraded and you can choose Sa manually.

No. Instrument audio and grading run on-device; optional Coach refinement sends bounded statistics, never a recording.
