Persian scale

The Persian scale is a musical scale occasionally found in guitar scale books, along with other scales inspired by Middle Eastern music. It is characterized by the liberal use of half steps (4), augmented seconds (2), and frequent use of chromaticism. Compare this to the one augmented second of the harmonic minor or the use of only two half-steps in all diatonic scales. This is also the Locrian mode with a major third and major seventh degree.

In Hindustani Classical Music, this corresponds to the raga Lalit.

The sequence of steps is as follows:^[1]

• H, +, H, H, W, +, H
• (W = Whole step - H = Half step - + = augmented second)

Beginning on C:

• C, D♭, E, F, G♭, A♭, B, C

This scale contains the following modes: ^[2]

• It is most closely related to the Phrygian dominant scale as their bottom tetrachords are identical.^[3] It can also be obtained by flattening the fifth degree of the double harmonic scale.
