The
3rd bridge is an
extended playing technique used on mainly electric guitars such as the
Fender Jazzmaster that has the
strings continue through to the tremolo piece. It is called the 3rd Bridge because some players utilized the unique sound that one can get out of playing in that area. Bands like
Sonic Youth and
Placebo are known for using this technique. Other more common use of the term contains a
prepared guitar with a rod, for instance a screwdriver or pencil, placed between the fretboard and strings. In that case the strings are played at the side of the fretboard, causing a resonating
overtone at the string part above the pickup.
Physical Explanation and examples
The third bridge divides the string into two pieces. When played at one part, the opposed part starts to resonate more or less, depending on their mathematical relation. On
harmonic positions the created
multiphonic tone is
consonant and increases in volume and sustain because of the reciprocal string resonance. The sound is comparable with the sound of bells of clocks.
Harry Partch allready experimented with this technique on his Kitara's with movable glass rods.
Glenn Branca adopted his theory and used amplified string tables for some of his symphonies. Also
Fred Frith and
Keith Rowe were early practisors of this technique, mainly inspired by adopting
John Cage's technique of the
prepared piano. Classical guitar duo
Elgart & Yates wrote a small book
Prepared Guitar Techniques in which the technique is described and used in the added written musical piece, although not defined with the term 'third bridge' yet.
Sonic Youth applied their guitars with screwdrivers, mainly in their early years. On their album
Confusion is Sex this technique is often used. Afterwards
Bradford Reed developed the
Pencilina and
Yuri Landman the
Moodswinger to explore the possibilities of this technique. Reed plays mainly with drumsticks hitting the strings as well, while Landman's technique is partly based on muting the opposed part while striking, causing a sound which reminds of a backwards-recorded sound.
