The notes of a chord played individually in sequence, rather than simultaneously.
Arpeggios are an essential component of guitar playing, as they provide a way to outline chords and create melodic movement within a harmonic context. They are used in various styles of music, from classical to rock, and can be played both on acoustic and electric guitars. By breaking a chord into its individual notes and playing them one at a time, guitarists can emphasise the underlying harmony while adding rhythmic and melodic interest to their playing.
Arpeggios can be executed using various techniques, such as fingerpicking, sweep picking, or alternate picking, and can be combined with other elements like slides, bends, or harmonics to create more expressive and dynamic phrases. Learning and practicing arpeggios across the fretboard can help guitarists improve their understanding of music theory, enhance their fretboard knowledge, and develop their improvisational skills.
