I've played this reel in A minor. It's often played in E minor as well but A comes before E in the alphabet and E doesn't necessarily stand for "easier" at the moment.
You'll here fiddle players playing this in A minor an octave lower in Donegal (if you're in Donegal listening to a fiddle session, that is). Some of them call it the "Gweebarra Reel".
