Arpeggios consist of the same notes as chords, but we play them up and down the keyboard note-by-note. Even so, arpeggios can still be viewed as positions that repeat as you travel up and down the piano.
Each arpeggio consists of one hand position that is repeated. When you get to the top note (right hand) or bottom note (left hand), you play your 5th finger on the root of the arpeggio (shown in green) which is not part of the repeated pattern.
