Beethoven’s piece is deceptively easy to play despite arpeggiated power chords and octave sweeps, which lend this piece a particular gravitas. However, the left hand and right hand parts are almost entirely separate, so you are not playing two different ideas at the same time.
The main first section is constructed of low, arpeggiated block chords with a simple melody. This gives the illusion that a lot of things are happening at the same time, but the rhythm stays the same throughout, so all you have to worry about are the notes.
There are a lot of notes and chords in this piece, and it also uses a lot of the piano’s range. Don’t be concerned, as it is much easier to play than it looks. Except for the last couple measures, there is only one note being pressed at a time in this piece.
Debussy imitated the sounds of the Gamelan by using the pentatonic scale, referring to a collection of five notes. There are a lot of chords in this piece, which can be daunting. But by remembering this scale of five notes, it is easier to play.
“Imagine” is John Lennon’s most famous song from his solo career, and it is a easy piece to play for a crowd. The verse is the chords C and F, and beginner pianists will learn the chords in root position with both hands, then learning to play the F chord in second inversion, with the C on the bottom.
