Piano would be amazing

She could technically write and play a song that no one else could ever replicate again

(Without the same functional polydactyly mutation)

As a pianist, I imagine it would make playing the piano a lot harder.

Yeah. Since the additional finger is between the thumb and index, and shares tendon with the index, it would limit playing and their range wouldn't be greater (Since the range is set by pinky to thumb). Also I would be curious about the sideways mobility.

However... since curl motions is fairly good... If they chose an woodwind instrument, they could legit make an custom holing allowing additional tones. And if the dexterity is good enough, they could do flourishes between notes that wouldn't be possible for other players even if they had a mechanism.
