Technical Foundations of Indian Music: Svara, Sruti, Raga Lakshana and Tala
This domain tests how pitch, raga identity and rhythmic cycle are defined in Carnatic theory. Questions often ask you to identify a melakarta, decode a tala, or explain a lakshana term without mixing units.
Core rules
- Nada is raw sound; sruti is the small interval used for tuning. Carnatic theory conventionally names 22 srutis, while practical svara positions use 12 semitone places and 16 svara names.
- Sapta svaras are Sa Ri Ga Ma Pa Da Ni. Sa and Pa are achala; Ma has M1 and M2; Ri, Ga, Da and Ni have three names each.
- Raga lakshana includes graha, amsa, nyasa, apanyasa, vadi, samvadi, arohana, avarohana and characteristic phrases. A melakarta has all seven svaras in order both ways; a janya raga may omit, zigzag or borrow svaras.
- Tala is a cycle of aksharas built from laghu, drutam and anudrutam. Sapta talas arise from laghu jaati values 3, 4, 5, 7 and 9 with fixed druta/anudruta patterns. Gati or nadai controls subdivision.
Worked example
Identify Mayamalavagowla and test a tala placement. It is melakarta 15, arohana S R1 G3 M1 P D1 N3 S, with the same avarohana. Because it is a melakarta, it has seven svaras in both directions and no vakra prayoga. In Adi tala, the 8 aksharas divide as laghu 4 + drutam 2 + drutam 2. At first speed, one svara per akshara fills the cycle; at second speed, two svaras per akshara are needed. The raga remains Mayamalavagowla; only the kala changes.
Traps that cost marks
Treating 22 srutis as 22 equal piano keys; calling every janya raga a melakarta; confusing laghu jaati with tala jaati; forgetting that Adi tala is chaturasra jaati Triputa; naming a melakarta number without checking its svara pattern.
