What effect do arpeggios have?
Arpeggios enable composers writing for monophonic instruments that play one note at a time (e.g., flute, saxophone, trumpet), to voice chords and chord progressions in musical pieces. Arpeggios and broken chords are also used to help create rhythmic interest.
What is the purpose of arpeggios?
Arpeggios create a fast, flowing sound. Besides using them for speed in playing, arpeggios add a kick to improvisation skills. Because an arpeggio contains all the notes of its chord, you can use them in your solos and link them to what's going on in the chord structure beneath you to create cool-sounding licks.
