Indian classical music is built on seven foundational notes (Saptak Swaras). Each note on the Web Harmonium keyboard has a Shuddha (natural) form, and some have Komal (flat) or Teevra (sharp) variants.
| Sargam | Full Name | Western | Variants | Description |
|---|---|---|---|---|
| Sa | Shadja | C | Shuddha | The tonic — fixed, never altered |
| Re | Rishabh | D | Shuddha / Komal | Natural or flat variant used in many Raags |
| Ga | Gandhar | E | Shuddha / Komal | Natural or flat; key to a Raag's mood |
| Ma | Madhyam | F | Shuddha / Teevra | Natural or sharp (Teevra) — the only sharpened note |
| Pa | Pancham | G | Shuddha | Fixed like Sa — never altered |
| Dha | Dhaivat | A | Shuddha / Komal | Natural or flat variant |
| Ni | Nishad | B | Shuddha / Komal | Natural or flat; defines a Raag's upper range feel |

A Saptak is an octave — a complete cycle of seven notes. The harmonium spans three full saptaks.
Lower Octave
Notes played in the lower register of the harmonium, marked with a dot below each note symbol. The chest voice naturally resonates here.
Middle Octave
The default octave — no markings required. Most practice begins here. It is the most natural range for both voice and finger-work.
Higher Octave
The upper register, marked with a dot above each note. Advanced players use this for climactic passages and complex Taan patterns.
