Which statement describes a false sequence?

• A. Second segment moves to a different tonal center.
• B. Second segment is exact intervallic transposition.
• C. Only part of first segment is transposed.
• D. First segment transposed diatonically.

Answer: (C)

A sequence restates a musical idea at a new pitch level by moving every note in the segment by the same interval, so the second part keeps the same intervallic relationships and contour as the first. If the entire segment is transposed by that uniform interval, the result is a true, consistent sequence, even if the tonal center shifts.

Describing the second segment as transposing only part of the first breaks that uniformity. When only a portion moves, the intervallic pattern isn’t preserved across the whole second segment, so the restatement loses its integrity as a sequence and becomes false.

The other possibilities fit the idea of a valid sequence: the second part can land in a different tonal center and still maintain the same overall intervallic plan; an exact intervallic transposition is the defining characteristic of a proper sequence; and transposing the first segment diatonically can still produce a sequential restatement within a tonal context.
