What interval sequence corresponds to the Lydian scale?

• A. W-W-W-h-W-W-h
• B. W-h-W-W-h-W-W
• C. W-W-h-W-W-h-W
• D. h-W-W-W-h-W-W

Answer: (A)

The Lydian scale is characterized by a specific sequence of whole and half steps that distinguishes it from other musical scales. The correct interval sequence for the Lydian scale is represented as whole step, whole step, whole step, half step, whole step, whole step, half step, which is typically denoted as W-W-W-h-W-W-h. This scale is derived from the major scale by raising the fourth degree, which gives it a bright and elevated sound, characteristic of the Lydian mode. The three whole steps at the beginning create an expansive feeling, leading to the half step that introduces a sense of resolution at the fourth scale degree. In contrast, the other interval sequences do not reflect the unique qualities of the Lydian scale. For instance, the sequences that start with fewer whole steps or include different placements of half steps would correspond to other modes or scales, such as major, natural minor, or different variations of the minor scale. Understanding this interval structure helps musicians recognize and use the Lydian scale effectively in composition and improvisation.
