Why do the tutorial keys sound different?
Some online harmoniums start C on Q. Rajaraman Iyer’s original starts C4 on E. A phrase copied from one layout will sound different on the other. Select Original tutorial, reset transpose to 0 and octave to 4, then check whether the video uses its own transposition.
Choosing Sa changes Sargam labels and the drone; it does not move the laptop key pitches. This site uses its own synthesised sound, so the timbre differs from the original’s recording.
