noun
harpist
HAHR-pist/ˈhɑːrpɪst/
A musician who plays the harp.

Etymology
The instrument name combines with an ending for someone who performs an activity. Here that activity is playing: a harpist is the musician, rather than the maker of the instrument.
In context
I meet the harpist. I didn't know who it was, but I saw the harp. I'm like, "You must be the harpist." and we're trying to communicate. She gives me the music.
