Arpeggiated Chords
The term arpeggiated chords is sometimes used to describe chords that are played with an arpeggio. However, guitarists tend to use the term to describe a different technique altogether.
An arpeggiated chord is where the plectrum or thumb is rolled across the strings slowly to articulate each individual note of the chord. The effect produced shouldn't sound like a strum or an arpeggio, more like a cross between the two. Below you will see an arpeggiated chord in published tablature and two ways of showing an arpeggiated chord in Internet tablature.
