How to Play the Dreamy Arpeggios in Beethoven’s “Moonlight Sonata”

For more than 20 years, I’ve had this idea in my head for a cool classic rock-style arrangement of Ludwig Van Beethoven’s famous piano piece, “Moonlight Sonata,” specifically the slow first movement (Adagio), which features a hauntingly beautiful chord progression unfolding as hypnotic triplet arpeggios supporting a sparse, poignant melody.

My idea, which I’ve finally written down, recorded and am excited to now share with you, was to arrange the piano’s left- and right-hand parts for two electric guitars—rhythm and lead—with bass and drums accompaniment, in a dramatic, British hard/prog-rock style inspired by Pink Floyd’s “Shine On You Crazy Diamond,” Led Zeppelin’s “Since I’ve Been Loving You” and Brian May’s playing on the Queen songs “We Are the Champions” and “In the Lap of the Gods…Revisited” (Sheer Heart Attack).

Here I present approximately the first half of the left-hand piano part—the accompaniment—which I perform with a slightly dirty bridge-pickup tone and a generous amount of concert-hall reverb, which helps emulate the ringing piano sound Beethoven achieved by using that instrument’s sustain pedal (see FIGURE 1).

This part of the arrangement has you playing an unbroken stream of slow, steady eighth-note-triplet arpeggios, à la Chicago’s “Color My World,” and requires some practice to master, as you will need to anticipate some of the challenging fingerings. It’s mostly flatpicked single notes, but you will need to use hybrid picking (pick-and-fingers technique) in order to simultaneously pluck two notes on non-adjacent strings on most of the chord changes.

First, familiarize yourself with the chord shapes, making sure your fretting fingers are properly positioned, then work on the picking, striving for an even triplet rhythm throughout. The goal is to try and allow the arpeggios and bass notes to ring together as much as possible, although that
