a way to get the notes of a chord without attempting to access 'window'

currently, the only way to get the notes of a chord, seems to be:
chordPlayer.buildChordPlayer.getChordInfo("some-chord")

it could be nice with something like:
chordPlayer.getChordInfo("some-chord")
that doesn't try to access the window object (like when building stuff in node):

CHORDPLAYER ERROR: ReferenceError: window is not defined
USAGE: new chordPlayer(chordName,[audioContext])

(it still works, though)
