84.105Mini-composition exercise

Write a 40-bar piece containing four distinct modulation strategies.

Requirements:

• establish first tonic for at least 8 bars
• one direct modulation
• one common-chord/pivot modulation
• one common-tone modulation
• one modulation without dominant preparation
• one modulation strongly prepared by V or ii–V
• one relative major/minor shift
• one parallel major/minor shift or equivalent modal change
• one chromatic-mediant move
• one modulation where melody arrives in new key before bass
• one where bass establishes new key before melody
• one modulation confirmed by a second cadence in the new key
• final return to original key should be simpler than the most remote modulation

The listener should clearly perceive different types of key change, not merely a sequence of transpositions.
