An arpeggio is a chord played one note at a time. Arpeggios can be played by either hand and any chord can be played as an arpeggio. The following example demonstrates the chords Dm and C played as arpeggios.
Arpeggios are often used by the left hand to accompany a melody played by the right hand.
Scarborough Fair is a folk music standard. The accompaniment in this arrangement consists of arpeggios of the chords Dm, C and F played by the left hand. Take it slowly at first and practice each hand separately if you need to.
Chopsticks is one of the most well known beginner’s pieces for piano. If your hand is not big enough to stretch the octave in bar 7 you can play the whole right hand part of the song using two hands. The left hand part consists of arpeggios of the chords C and G7. Practice each hand separately at first if you have trouble co-ordinating the two parts. This song is in the key of C major as indicated by the key signature (i.e., no sharps or flats).
