Sa is the home note of sargam, the Sa Re Ga Ma Pa Dha Ni names used across Indian music. On a harmonium, Sa is not printed on any key. You choose it, and every other note is counted from it. Choosing well matters most if you sing while you play, because a Sa that is too high or too low makes every exercise feel harder than it is.
01 Sa moves; the keys do not
On a piano-style keyboard, the same pattern of white and black keys repeats every twelve keys. Whichever key you call Sa, Re is two keys up, Ga is four keys up, Ma is five, Pa is seven, Dha is nine and Ni is eleven, counting black keys too. Move Sa and the whole pattern moves with it, so a phrase learned from one Sa can be played from any other.
02 A common starting point
Many beginners start with Sa on C, the white key just to the left of a pair of black keys. From C, the natural (shuddha) notes of the scale are all white keys, which makes the first patterns easy to see. It is only a starting point. Many singers settle on a different key, often one that uses black keys.
03 Find the Sa that suits your voice
- Hum first. Hum a relaxed, steady note in the middle of your range.
- Match it. Press keys near that pitch until one blends with your hum without a wobble between them.
- Test a scale. Sing Sa up to the next Sa. If the top feels pinched, move Sa down a key. If the bottom feels weak, move it up.
- Write it down. Note the key you chose so every practice session starts from the same place.
04 Mark it and hold it
A small removable sticker on your Sa key saves a lot of hunting in the first weeks. Before an exercise, hold Sa for a few seconds and sing it softly. Holding the home note against a steady reference is the simplest way to train your ear to hear it.
05 Playing with others
When you practise with a teacher, a singer or a recording, use their Sa, not yours. Ask which key they use before you start, and move your own marking for that session.
06 Doing this with Soloist Harmonium
Find your Sa asks you to sing, hum or play one comfortable, steady note. It only changes Sa when the microphone evidence is clear. Otherwise your current choice stays, and you can retry or pick Sa by hand. The keyboard labels, in Roman, Devanagari or Gurmukhi, and the reference drone then follow the Sa you chose. All of this is free, and audio stays on your device.

Questions
Which key is Sa on a harmonium?
Sa is not fixed to one key. It is the home note you choose. Many beginners start with Sa on C, the white key just to the left of a pair of black keys, then move Sa up or down to suit their voice or their teacher.
How do I know which Sa suits my voice?
Sing a relaxed, steady note in the middle of your range, the kind you could hold without strain, and find the key that matches it. If the higher notes of a simple scale feel pinched, move Sa down a key or two. If the lower notes feel weak, move it up.
Why does my teacher use a different Sa from me?
Voices differ, so singers often pick different home notes. When you play together, use the same Sa as the person you are playing with, then return to your own for solo practice.
