Which option is not a sequence type described in the material?

• A. Modulating sequence
• B. Real sequence
• C. False sequence
• D. Inverting sequence

Answer: (D)

The idea here is to recognize which sequence types are described in the material by how the melodic pattern behaves. A modulating sequence moves the same pattern into a new key center, changing where it feels at home harmonically. A real sequence keeps the exact intervallic relationships while shifting to higher or lower pitches, so the pattern sounds the same but sits in a different pitch space. A false sequence resembles a sequence but does not fully maintain the strict pattern, so it’s not considered a true sequential repetition within that framework. An inverting sequence, which would flip the direction of the intervals (up becomes down, and vice versa), isn’t listed as a described sequence type in the material. Therefore, the inverting sequence is the one not described. For context, think of modulating as moving the pattern to a new tonal area, real as maintaining identical interval structure across pitches, and false as a mimic that breaks the pattern.
