Notes: C, Db, E, Gb, G, A, and B - Key: C - Origin: North Indian - Category: Octatonic Scales
The C Marwa Thaat uses eight notes per octave. Because of this same reason it is a member of the so called Octatonic -scales that have Eight-note (or Eight-tone). On the piano keyboard, it is made up of two black keys: Db, and Gb and five white keys: C, E, G, A, and B. This combination makes this scale - as well as the C Purvi Thaat, C Bhairavi Thaat, and C Bhairav Thaat - as great choices for composing or improvising North Indian music.
If we take a look a the key signature of the C Marwa Thaat Scale we can find it has two flats and no sharps. Therefore, on sheet music you will find two accidentals on the score. The notes of this scale are: C, Db, E, Gb, G, A, and B.
