Overview of Sruti

In Carnatic Music, the term Sruti is fundamental. Derived from the Sanskrit root word Sru (meaning “to hear”), Sruti refers to the smallest interval of pitch that the human ear can detect and distinguish. It serves as the foundation for all musical notes (Swaras).

While an octave contains infinite sounds, Indian classical music theory identifies 22 distinct Srutis or microtones within an octave (Saptaka). These distinct microtones form the basis for the 7 Swaras.

Key Concepts

  • Definition: That which is heard or audible musical sound.
  • Pitch: Sruti represents a specific pitch value. While Western music typically uses 12 semitones, Carnatic music utilizes 22 Srutis.
  • Tonal Reference: The concept of Sruti relies heavily on a constant tonal reference, known as the Adhara Shadja. This base pitch acts as the drone (usually provided by the Tambura) against which all other Srutis are measured.
