An arpeggio is a musical technique in which the notes of a chord are played in succession, rather than simultaneously. This creates a flowing, rippling effect that can be used to add interest and complexity to a melody or harmony.
To play an arpeggio, you would typically start with the lowest note of the chord and play each note in sequence, moving up the chord until you reach the highest note. For example, if you were playing a C major arpeggio, you would play the notes C, E, and G in sequence. Arpeggios can be played on a variety of instruments, including saxophone, piano, guitar, and harp, and are often used in classical, jazz, and popular music.
