That's what I understood it to be. I don't know of many chords that have two notes on the same string, so David's leesons have left me questioning.
That's right, an arpeggio is a chord played one note at a time.
Usually, when you play a chord on the guitar, the notes of that chord are arranged a little differently than its theory construction.
For example, a C Major chord is a chord made out of the Root, Major 3rd and 5th.
If you were to play that chord on a piano it would be easy. But on the guitar, sometimes you'll need to reverse some of these notes for the fingering to be doable.
When playing an arpeggio, you are not limited to a vertical fretboard since you are playing one note at a time.. That is why you can find arpeggio fingerings spread across the fretboard using sometimes the same string for several notes.
Does that help?
