Fundamentals of Indian Music: Swara, Sruti, Raga, Tala and Notation
What the exam tests
This domain checks whether you can use the basic vocabulary of Hindustani music precisely: nada, sruti, swara, raga and tala. Expect definition questions, classification of swaras, and short identification tasks rather than long essays.
Core rules
- Sruti is a microtonal interval; the tradition speaks of 22 srutis in an octave. It is not a synonym for swara.
- The seven shuddha swaras are Sa, Re, Ga, Ma, Pa, Dha, Ni. The komal forms are re, ga, dha and ni; Ma has a tivra form. Sa and Pa are achala, fixed.
- A raga is more than a scale. It needs aroha, avaroha, vadi, samvadi, pakad, chalan and usually a time or mood association.
- A thaat is a classificatory scale used by Bhatkhande; it is not a raga.
- Tala is a cyclic rhythmic framework built from matra, vibhag, tali, khali and sam.
Worked example
A phrase uses Sa, komal Re, Ga, Ma, Pa, komal Dha and komal Ni. The scale matches Bhairav, whose usual vadi is Dha and samvadi Re. The correct answer names Bhairav as a raga, not as a thaat. The reasoning must add that a scale alone is only a clue: raga identity also depends on pakad and chalan.
Traps
Do not call every seven-note scale a raga. Do not mark Sa or Pa komal. Do not confuse tala with laya: tala is the cycle, laya is speed. In notation, sam is the first matra, not every tali.
