📐 Music Theory
12 swaras, shrutis, komal-tivra and ornaments.
📐 The Science Behind the Art
Music theory is the study of the practices and possibilities of music — understanding why music works and how it is organized.
Sargam — Indian note names:
Sa (Shadja) · Re (Rishabh) · Ga (Gandhar) · Ma (Madhyam) · Pa (Pancham) · Dha (Dhaivat) · Ni (Nishad)
Full name of the system: Sargam (Sa-Re-Ga-Ma). The word "Sargam" itself comes from the first four notes.
Komal swaras (flat): Komal Re, Komal Ga, Komal Dha, Komal Ni
Tivra swara (sharp): only Tivra Ma
Achal swaras (fixed): Sa and Pa — never altered
12 swaras in one octave:
Sa | Komal Re | Shuddha Re | Komal Ga | Shuddha Ga | Shuddha Ma | Tivra Ma | Pa | Komal Dha | Shuddha Dha | Komal Ni | Shuddha Ni
These correspond exactly to the 12 semitones (chromatic scale) of Western music.
Indian classical theory recognizes 22 shrutis per octave — finer divisions than the 12 semitones of Western equal temperament. This gives Indian music its ability to produce subtle emotional colorings impossible on a piano.
Bharata Muni's Natya Shastra (~200 BCE) first documented 22 shrutis. Each swara spans 2-3 shrutis.
Komal Re is slightly different in different ragas — the shruti used defines the emotional character.
Andolan — slow oscillation on a note (especially komal Ga in Darbari) — uses shrutis in between standard positions.
Alankar (ornament/exercise) — systematic pattern exercises on sargam. Foundation of classical training.
Example: Sa Re Ga / Re Ga Ma / Ga Ma Pa / Ma Pa Dha / Pa Dha Ni / Dha Ni Sa (aarohan)
Gamak — rapid shake/oscillation on a note
Meend — glide/portamento between two notes (essential Indian ornament)
Murki — rapid turn of 3-4 notes
Khatka — quick grace note
Kan swara — grace note — touching a note lightly before the main note

AnimationSa=C only in the natural key. In performance, Sa can be set to any comfortable pitch (vocalist's choice).
Music Theory Deep Dive
InteractiveAchal (Fixed — never altered):
1. Sa (C) — always natural
2. Pa (G) — always natural
Shuddha (Natural/Pure):
3. Shuddha Re (D)
4. Shuddha Ga (E)
5. Shuddha Ma (F)
6. Shuddha Dha (A)
7. Shuddha Ni (B)
Komal (Flat — lowered by shruti):
8. Komal Re (D♭)
9. Komal Ga (E♭)
10. Komal Dha (A♭)
11. Komal Ni (B♭)
Tivra (Sharp — raised by shruti):
12. Tivra Ma (F♯) — the ONLY tivra swara
Memory tip: Sa-Pa are fixed pillars. Re-Ga-Dha-Ni can be komal (4 swaras). Only Ma can be tivra (1 swara). Total: 2+5+4+1 = 12.
Example: Shuddha Ga (E) — used in Yaman, Bilawal, Bhimpalasi. Bright, clear sound.
Komal (soft/flat) — lowered by one shruti (approximately a semitone). Creates a softer, more emotional quality.
Komal Re: Bhairav, Bhairavi, Todi
Komal Ga: Bhairavi, Bageshri, Kafi, Bhimpalasi — creates sadness/tenderness
Komal Dha: Bhairav, Bhairavi, Todi
Komal Ni: Khamaj, Kafi, Bhairavi
Tivra (sharp/intense) — raised by one shruti. Only Ma can be tivra.
Tivra Ma (F♯): Yaman, Yaman Kalyan, Hindol — creates a floating, romantic evening quality
How they affect a raga's mood:
• Ragas with all shuddha swaras (Bilawal) = bright, active
• Ragas with komal swaras = emotional, softer, devotional
• Raga Bhairavi (all komal Re, Ga, Dha, Ni) = maximum emotional depth — used as farewell raga
• Raga Yaman (only tivra Ma) = romantic, evening glow
• Raga Todi (komal Re, Ga, tivra Ma, komal Dha) = most complex combination — meditative
