I have hacked through the Chopin Ballades for years now. I started learning the first one in high school, and in adulthood I played through #3 and #4 often enough that I can, well, hack through them. I never spent the time working everything out and polishing; I just kept sight reading until I could blaze through it.

This past week I decided it was time to actually sit down with #4 and work it out more carefully. Today I got to this pictured section which, when sight reading, had always thrown me for a loop. Practicing the right hand by itself, I finally realized what makes it such a pain.

It’s 6/8 time. On the first line, the bass has gone to triplets in each eighth note. Then on the second line, the right hand picks up triplets per eighth, while the left switches to sixteenths. Ok, that’s 3 against 2, no big deal.

But while the right hand is in triplets, the pattern written (as indicated by the eighth notes on the up stems) is a four-note pattern, almost an Alberti pattern. So, you have what is by pattern a four-beat pattern, played as triplets against two in the bass. My brain wants to interpret that as four against two, which is very simple. But it’s not - rhythmically, it’s 3 against 2, but the 3s are logically and musically grouped in sets of four. This one is gonna take my brain a while to work out.
