E♭ Persian Scale in Practice

The E♭ Persian Scale uses the key signature of 3 flats (B♭, E♭, A♭). Eb major has three flats and a rich, full sound well suited to brass instruments. It is widely used in jazz, classical music, and is the home key for Eb instruments. On guitar, E♭ positions offer comfortable transposing instrument keys for this scale.

The Persian scale has a distinct Middle Eastern character with its flat 2nd and 5th degrees combined with a natural major 3rd and leading tone. It evokes the musical traditions of ancient Persian culture. When played starting on E♭, the 7 notes are E♭, E, G, A♭, A, C♭, D. In this key the signature has 3 flats (B♭, E♭, A♭). Eb is the concert key for alto saxophone and baritone saxophone playing in their native C, and it is a staple of big band and jazz ensemble writing. Eb is heavily used in R&B, soul, and gospel music, where horn sections in Bb and Eb instruments can play without difficult transpositions.
