Class 6 Visual Arts Textbook chapter 6 music and your emotions question answer
Achal swaras (Sa, Pa) remain unchanged in pitch across compositions. In contrast, Chala swaras (Re, Ga, Ma, Dha, Ni) can be modified as Komal (flat) or Teevra (sharp), creating different musical moods. This flexibility allows artists to explore various ragas and express emotions uniquely. The combination of both types gives Indian classical music its rich, diverse melodic structure.
