Subordinate Theme


Short Answer

  1. change in tonality (subordinate key), looser formal expression, new melodic-motivic material
  2. by inverting the prolonged tonic; by setting the tonic on metrically weak positions; by undermining the prolongation with a dominant pedal
  3. each subordinate theme must end with a PAC
  4. because a subordinate theme cannot conclude with a HC, any appearance of this cadence type must be "internal" to the theme
  5. the first part will end with an internal HC (or dominant arrival); the second part will begin with a new initiating function
  6. the cadential close of one thematic unit brings at the same time the new accompanimental pattern of the next thematic unit, which itself begins in the following measure
  7. modal shift, chromaticism, tonicization of more remote regions, modulation
  8. the transition lacks a concluding function and the subordinate theme lacks an initiating function
