Let's Practice 1.6
Haydn, String Quartet in G, Op. 54/1

  2. prolongational; the outer voices move in parallel motion, thus suggesting sequence, but a genuine sequence would have brought a III6 harmony instead of I6 in the second half of m. 5
  3. tonic prolongational
  4. second half of m. 10; complete
