Major Blues Scales on Piano

The major blues scale adds a chromatic passing tone (the ♭3, or "blue note") between the 2nd and 3rd degrees of the major pentatonic scale. This single addition transforms a bright, folk-like scale into something with swing, attitude, and blues inflection — perfect for soloing over major-key blues progressions and jazz standards.

Formula: W–H–H–WH–W–WH
Intervals: P1–M2–m3–M3–P5–M6–P8
Scale degrees: 1–2–♭3–3–5–6
Sound: Swinging, bluesy, bright with grit
Also known as: Major pentatonic with a blue note (♭3)
