Action: Refers to the playability caused by the height of the strings above the frets, the closer to the frets that the strings are the better the action.
Alternating Bass: A finger picking technique where the thumb plays a steady bass line while alternating between two or three strings.
Arpeggio: A series of individual notes played one at a time in a repetitive pattern. An example would be playing the notes in a chord one at a time repetitively up and down.
