what is the cadence in measure 4? a. perfect authentic cadence b. imperfect authentic cadence c. half…

Brief Explanations:

To determine the cadence, we need to analyze the chord - tone relationships at the end of measure 4. A perfect authentic cadence has the dominant (V) chord moving to the tonic (I) chord with the root in the bass of both chords and the tonic chord in root position. An imperfect authentic cadence has V - I but the tonic chord is not in root position or the root is not in the bass. A half - cadence ends on the dominant chord. A plagal cadence is IV - I. Without seeing the actual chords in measure 4, we can't give a definite answer, but we know the definitions of each cadence type.

Answer:

We need more information about the chords in measure 4 to determine the correct option.
