In Indian classical music, which concept denotes the fundamental melodic structure defined by a specific order of ascending and descending notes?

Explanation

Raga. In Indian classical music, a Raga denotes the fundamental melodic framework. It is defined by a specific order of ascending (Aroha) and descending (Avaroha) notes. A raga also prescribes important notes (Vadi– Samvadi) and conveys a particular mood or emotion (Rasa). Laya refers to tempo, Tala to rhythm, and Alankara to ornamental patterns.
