After I learned the bass part for "Confusion," I learned most of the bass part for "Mr. Blue Sky." I did a bit of work on this to-day before I recorded it too. I had one note wrong, and I figured out a phrase I was stuck on (I was right that the bass part arpeggiates two chords, but because there's a key change there, I wasn't expecting one of those chords to be Eb).
I played an extra F note at the end. It's not there in the original, but it sort of resolves my recording. I don't know the next section, and it would have sounded weird to stop abruptly.
