Raga Marwa is derived from Marwa Thaat. It is a dusk/ early evening Raga which uses six notes in the ascent and in the descent. Pancham is not used. Marwa uses Tivra (sharp) Madhyam and Komal (flat) Rishabh. All other notes are Shuddha (full). The derivative ragas out of this structure are grouped under the broad head of Marwa Thaat.
