Silencing Bass Strings
Because the guitar's bass strings (^% and $), once plucked, have a far greater sustain or time of sounding than that of the treble strings (#@ and !),it is important to control their duration (just as the dampening pedal on the piano), principally by using methods involving p.
Methods of Silencing Bass Strings
- Pressure release of left hand finger (indicated M.1)
- Rest stroke p (M.2)
- Resting p (M.3)
- Resting back of p (M.4)
- Combining M.3 and M.4 (M.5)
- Pressure release of left hand finger: This technique has already been used throughout the method (see section on staccato), and it is obvious that a fretted note, i.e. any note other than open string notes, will immediately cease to sound once the finger is removed from the string, thereby providing the desired silence (Ex. 1).
- Rest stroke p: The preceding chapter (page 178) has already explained how a rest stroke p automatically silences the adjacent higher string upon which it rests (Ex. 2).
- Resting p: Perhaps the most common method of silencing a bass string is to rest on the string using the pad of the thumb (p) as has been explained previously in the section on staccato (Ex. 1, page 169)
- Resting back of p: Another method is to rest the small section of skin bordering the nail against a lower string immediately before (or after) plucking an adjacent higher string, i.e, pluck @ and # just before plucking push back against ^ with the back of p, before continuing on to pluck % as normal, rest or free stroke (Ex. 3, photo A).
- Combining M.3 and M.4: Two bass strings can be silenced together by inserting p between the strings, pressing against both simultaneously using methods M.3 and M.4 (Ex. 4f photo B).
Try incorporating the different methods using previously studied pieces, i.e. Study (page 71), Andante (page 105), Study in Ligados (page 111), Dance in A (page 119), Lesson in A (page 155).
Remember that it is an extremely good idea to rest p on a bass string (using M.3) or strings (using M.5) when not in use, as it steadies the hand, prevents the guitar from producing unwanted overtones and harmonics (which may occur when playing certain notes on the treble strings) and provides a reference point for finding required bass strings. You will notice references for the different methods (M.2, M.4 etc.) in some of the pieces that follow.
