Marva (raga)
Marwa is an hexatonic Indian raga; Pa (the fifth tone) is omitted. Marwa is also the name of the thaat.
Aroha and Avaroha
Arohana
Ṇi re_ Ga Ma_ Dha Ni re# S'
In the Western scale this would roughly translate to: C C-sharp E F-sharp A B c
Avarohana
re_ Ni Dha Ma_ Ga re Ṇ Ḍ S
The Ma is actually Ma Tivratara, which is a perfect fourth above re komal (which is 112 cents above Sa))
Vadi and Samvadi
The Vadi is komal Re, while the Samvadi is shuddh Dha. Notice that these do not form a perfect interval. So V.N.Paṭvardhan says "It is customary to give Re and Dha as vādi and saṃvādi, but seen from the point of view of the śāstras (treatises) it is not possible for re and Dha to be saṃvādī (i.e. consonant) to each other. For this reason, in our opinion it is proper to accept Dha as vādī and Ga as saṃvādī" On the other hand if Ga receives too much emphasis, it would create the impression of raga Puriya
Pakad or Chalan
Sa is omitted within a taan; it may only be used at the end of a phrase and even then is used infrequently. Bhatkhande gives the pakad as Dha Mâ Ga re, Ga Mâ Ga, re, Sa. Patwardan has shown the mukhya ang as re Ga Mâ Dha, Dha Mâ Ga re, but points out that the raga is also clearly indicated by: Ṇi re Ga Mâ Dha, Dha Mâ Ga re Ṇi re Sa.
The chalan given by Ruckert is: Ṇi Ḍha re__ Ṇi Ḍha Ṃâ Ṇi Ḍha Ṇi Ḍha Sa__ re' Ga Mâ Dha__ Mâ Ni Dha Mâ Ga re__ Sa Ṇi Ḍha re Sa__
