Jonathan Coulton has already put up the chords for the tune he wrote for the game Portal. But the J-Dog don’t roll with tabs. So I thought I’d have a stab the fingerpicking bit in the first part of the song.
The song is played on a low-G ukulele and the picking pattern is T, I, M, I (thumb, index, middle, index). This pattern makes up the majority of the first section of the song:
Then moves on to this pattern for the turnaround:
Far be it from me to tell Jonathan Coulton how he plays his own songs, but I’m fairly sure there’s a 7th note in that A chord. He has it as a plain A chord on his write up of the chords, so I may be completely wrong.
The second time around, the series finishes off with a sweep of a Bbmaj7 chord.
If you don’t have a low-G uke, you can play it the sweetafton way. She uses the same chords but the picking pattern is slightly different.
