Final answer:
A perfect fifth above E-flat is A#.
Step-by-step explanation:
A perfect fifth is an interval in music that consists of seven semitones. To find a perfect fifth above E-flat, we count seven semitones up from E-flat. In the case of E-flat, the notes E, F, F#, G, G#, A, and A# make up the seven semitones to form a perfect fifth. So, a perfect fifth above E-flat is A#.
