Reference droneA sustained tone at the tonic this performer saved — play it under the
recording to hear the performance against a steady reference.
How to read this.
The curve below is an algorithmic pitch estimate (librosa pyin), plotted as
cents relative to the tonic you set
(cents = 1200 × log₂(f / tonic)).
1 · Set your tonic
Drag the line over the raw pitch (in Hz) to the reference you hear as the
tonic, or type it, then save it.
2 · Melograph
Time on the x-axis, cents relative to your tonic on the y-axis. The line breaks
wherever the pitch tracker found no voiced pitch — gaps are never bridged.
0:00 / 0:00
Shaded band = pyin voiced-probability (wider means a less certain estimate).

Guided listening
Notes below are written by people — teachers and tradition-bearers — and stored as an
exemplar in the database. Ragascript writes none of them: it only places each note as a marker at its
moment on the melograph above. Each note shows who wrote it and the lineage it comes through.
3 · Pitch dwell histogram
All cents folded into a single octave (cents mod 1200), showing how long the
performance dwelt near each pitch relative to your tonic.
