Question

which kind of harmony did classical period composers prefer?
○ tonic-dominant-tonic (i-v-i)
○ tonic-submediant-tonic (i-vi-i)
○ tonic-subdominant-tonic (i-iv-i)
○ tonic-median-tonic (i-iii-i)

Explanation:

Classical period composers preferred the tonic - dominant - tonic (I - V - I) harmony. This harmonic progression is fundamental in functional harmony, which was highly developed and widely used during the Classical period. The dominant (V) chord creates a strong pull back to the tonic (I), providing a sense of resolution and closure that is characteristic of Classical music's balanced and structured style.

Answer:

tonic - dominant - tonic (I - V - I)
