Begin near speaking comfort
Hum or sing an easy sustained note without searching upward. Match its nearest harmonium key, then test the surrounding tonic choices.
Check three points
Try lower Pa, middle Sa, and upper Sa. If one end requires pressing, breathiness, or a changed vocal quality, move the tonic and test again.
Context can change the choice
A teacher, ensemble, fixed-pitch instrument, composition range, or current vocal condition may require a different Sa on another day.
Beginner practice
- Use Find My Sa for a starting pitch.
- Test lower Pa and upper Sa quietly.
- Save the Sa only after both ends feel sustainable.
Common mistakes
- Choosing the highest impressive tonic.
- Treating a one-note detector as a medical or permanent range test.
- Turning the drone up until it masks the voice.
