A Hungarian major Scale
A Hungarian major contains 7 notes: A, B♯, C♯, D♯, E, F♯, G. It has 4 sharps: B♯, C♯, D♯, F♯. The step pattern is W+H–H–W–H–W–H–W.
A bright, folk-dance scale with a distinctive Eastern European flavor. The raised 2nd combined with the Lydian #4 and dominant b7 creates a sound that's festive, exotic, and full of forward momentum.
The formula is 1, #2, 3, #4, 5, 6, b7. The #2 creates an augmented 2nd from the root, immediately establishing its exotic character. The bright #4 (Lydian) and b7 (dominant) place it in Lydian-dominant territory but with that extra Eastern European twist from the #2. Used in Hungarian folk music and by classical composers inspired by Hungarian traditions.
Works over dominant 7th chords when you want to add folk-dance energy with more exotic flavor than simple Mixolydian. The #2 sits one fret above the normal 2nd — emphasize it as an approach note to the major 3rd for the most characteristic sound. The overall shapes are comfortable and follow familiar dominant patterns.
