In Hindustani classical music, what is the term used for a fixed or structured musical composition?

Explanation

A Bandish is a fixed composition in Hindustani music set to a specific raga and tala, forming the base for improvisation. It includes lyrics and is sung in slow (vilambit), medium, or fast (drut) tempo. Unlike Kriti (Carnatic), Gamaka (ornamentation), or Rasa (emotion), Bandish is the main melodic framework.
