Romanian major, also known as lydian dominant flat 2 or flat 9, is a musical scale, noted for its flattened 2nd and sharpened fourth degrees, the latter a distinctive feature of Romanian traditional music. A C Romanian major scale has the notes C, D♭, E, F♯, G, A, B♭, which is 1, ♭2, 3, ♯4, 5, 6, ♭7. Though it is called a major scale, it is typically played over a C13 (♭9) (♯11) (also F♯ major over C) dominant chord. This is an enharmonic mode of B Harmonic Minor (A# & C# in B Harmonic Minor, Bb & Db in C Romanian Major), along with D Harmonic Major (C# in G Harmonic Major, Db in C Romanian Major). The root note of F Harmonic Major is raised a semitone to F#, and the root note of D Aeolian Dominant lowered a semitone to Db. There is also a ♮6 with the Db Super Lydian Augmented scale, lowering the B♮ to Bb.
