F Purvi Raga
F · G♭ · A · B♭ · B · C · D♭ · E
Based on the North Indian raga Purvi, F Purvi Raga is an eight-note set containing both a natural and a raised fourth alongside a flat second, major third, flat sixth, and major seventh. Having both fourths available gives melodies unusual room to move. Best suited to slow, ornamented playing.
