Major Ninth Intervals

A major ninth interval is the distance from any note to a note fourteen half-steps away either ascending or descending. Another definition is an perfect octave plus a major second. It is a dissonant interval.

Playing major ninths on the guitar requires using the pick to strike the low note and the second finger to strike the high note. Strike the low note with a downward motion and strike the high note with an upward motion, as if you are trying to pinch the strings.
