An arpeggio is a musical technique where the notes of a chord are played in sequence, rather than simultaneously. This creates a flowing sound, often used in various genres of music, including classical, jazz, and pop. Arpeggios can be played on instruments like the piano, guitar, or harp, and they help to add texture and movement to a piece. In music notation, arpeggios are often indicated by a wavy line or the abbreviation "arpeggio." Musicians can practice arpeggios to improve their finger dexterity and understanding of chord structures. They are also commonly used in improvisation, allowing musicians to create melodic lines that complement the harmonic background.
