Here starts what I consider to be a very long journey.   I’ve been listening to a few recordings of this, and it’s challenging, to say the least, to figure out where the phrase boundaries go.  First, I’ll learn the notes, and then figure how they should be in my hands.  I’m working on the first two lines, and I should have clips of that over the break.   I’m going to need to work on that chord trill a few hundred thousand times.

How did you work through this when you first encountered it?
