The scales of Pahadi are as follows :
Aarohanam (Ascending) : S R2 G3 P D2 P D2 S’
Avarohanam (Descending) : N3 D2 P G3 M1 G3 R2 S N3 D2 P D2 S
Pahadi is considered a janya raga, derived from Dhira Shankharabharanam (see below) which is 29th on the Melakarta Scale.
It is a Hindustani Raga, arising from the folk tunes of Kashmir. ‘Peace, power, pathos, poignancy’ says Haresh Bakshi about the moods of this raga in his blog. This raga will be familiar to listeners of Hindi film music as it is a favourite among composers. ‘ Chaudvin Ka Chand’ in the film of the same name, ‘ In hawaon mein, in fizaon mein’ in Gumrah, both by Mohammad Rafi and ‘ Sawan Ka Mahina’ by Mukesh & Lata Mangeshkar are all well-known and well-loved songs based on Pahadi. But what I like best are the many dhun’s that Hariprasad Chausaria has performed in Pahadi; somehow the bansuri brings out the best moods of this raga. You can listen to a nice example here.
Note : The 12 notes in the octave are named as below. Please note that C is used as Sa for the sake of simplicity as the scale is relative in Carnatic Music. Also note that the scales paint only a superficial picture of the raga as the gamakas(ornamentations) are a very important part of a raga.
