If you are looking for something new, learning to add arpeggios to your guitar practice can create some great variety and melody to your guitar playing.
And remember, Arpeggios are not only played fast, they can also be used slow and melodically to add new phrasing and chordal creativity.
Arpeggios are really just "broken chords" by definition, so we are looking to learn how to play them across the guitar strings to break up the typical "guitar scale" type playing. Arpeggios provide a wonderful method of "shifting" acroos the guitar fretboard to move positions and create a smooth "flow" of movement across the guitar neck.
