Final answer:
The trio in movement 3 of Eine Kleine Nachtmusik contrasts with the minuet by having a different meter, while maintaining the same tempo.
Step-by-step explanation:
The third movement of Mozart's Eine Kleine Nachtmusik, which traditionally should be a minuet and trio, actually presents a contrast between the minuet section and the trio section. The correct answer to the question 'How does the trio contrast from the minuet in movement 3 in Eine Kleine Nachtmusik?' is D) Same tempo but different meter.
The minuet typically has a moderate tempo and is composed in 3/4 time, characterized by an elegant and formal dance rhythm. The trio, often contrasting with the minuet, maintains the same tempo but is composed in a different meter or has a distinctly different character which can sometimes include a change in instrumentation or key, though not necessarily in the piece in question. However, the key point here is that even though the trio has a different feel, the tempo remains consistent with the minuet.
