Moonlight Sonata, 1st mvt.

I sat down to figure out the Moonlight without looking at the score, which is a slightly silly exercise because I’ve played it before — but the first time I really played it, I was sixteen and followed every marking on the page. I wanted to hear what my ear would reach for now, thirty years and one jazz teacher later.

The first thing that surprised me: the famous triplet figure isn’t doing melodic work. It’s weather. It’s the pedal tone that makes the chord shimmer, and the whole movement is organized around the bass — a slow half-step descent in the left hand that pulls the harmony along behind it like a tide. Once I heard that, the top line more or less played itself. The melody is in the top notes of the triplets, but it moves so sparingly that if you play it you’ll overdo it. Let it emerge.

The second surprise was harmonic. I kept trying to hear a V7 where the piece actually goes to a diminished chord, and it kept feeling wrong. Eventually I slowed down, played the bass notes one at a time, and realized the move I was missing is the Neapolitan — a D major chord in the key of C♯ minor, which sounds like the sun coming through for exactly one beat before the piece returns to its weather. Beethoven voiced it so you almost don’t notice. But your ear does.

A practical note: I played this on the Kawai CA-99 with the damper held through each bar, not each beat. The magic here is harmonic blur, not clarity. If you change the pedal too often you get geometry where Beethoven wanted atmosphere. Commit to the smear.
