(upwards slur or hammer)
The ascending ligado (indicated by —) is achieved by hammering any left hand finger on to the required note either from an open string, i.e. Exercise A, or from a lower finger, 1.e. Exercise B. It is also necessary to prepare the ligado finger somewhat further from the fretboard than normal in order to achieve the required strength for the hammer.
Note: move only the finger, keep the hand completely steady.
remember to alternate R/H fingers on each plucked or "pre-ligado" note.
