Watch the Queenie's Waltz online guitar lesson by Adrian Legg from Fingerstyle Revisionist: Adagio Songbook
Moving on to the second verse (Section C and D), we're doing quite a bit of the same things we were doing in the first part - playing legato and using the thumb to mark the bar on the bass.
Now, you don't have to be strict about the phrasing I've written in the notation, maybe go for my phrasing the first time, but don't be afraid to vary it a little as you go through the piece. If someone's going to be waltzing around for a long time, you're going to want to change it around a bit for them! I've also added in a couple of extra bars at Bar 26 and 27 to add a bit of "hang" to the section; feel free to do a variation on them as well.
