THE ZITHER BANJO is really a constructional variation
of the banjo and as such has five strings tuned to the same pitch and
notes.
This type of instrument started with W. Temlett's
patent closed-back banjo of 1869 (Temlett always called himself the
"pioneer of the zither banjo"). The American C. E. Dobson
patented an "Improved Closed Back" banjo in 1878 but it
was Alfred D. Cammeyer (an American who had settled in England) who
perfected the zither banjo and introduced it to this country in 1888.
The vellum diameter of the zither banjo varies between
7 inches and 9 inches and it rests on a circular metal casting suspended
in a wooden hoop with convex back, approximately 9 inches to 11 inches in
diameter, by metal "S"-shaped brackets (varying in number)
affixed to the upper edge of the wooden hoop. The top-band (or bezel) is
usually of cast metal with a number of lugs round its diameter through
which pass screwed bolts which engage in the tapped holes in corresponding
lugs on the inside casting. By tightening these screws, pressure is
applied to the top-band which then increases tension on the vellum.
Zither banjos have always dispensed with the side fifth
peg; the octave string passing through a tube inserted under the
fingerboard and emerging at the peghead. It has been usual to fit guitar
machine-heads to the zither banjo so that the peghead presents a
'three-a-side" appearance—although only five of the tuning
mechanisms are used. (Some manufacturers have in the past produced
machine-heads specially for the zither banjo, with two pegs on the bass
side and three on the treble side but the balanced machine heads present a
better appearance). The machine heads are usually fitted vertically in a
cut-out recessed head.
In the beginning the zither banjo was always played by
vibrating the strings with the nails of the right hand (these were
developed and carefully tended by the true artist for this purpose) and
the instrument was particularly suited for the slower type of solo where
sostenuto could be employed. When forced, the zither banjo is inclined to
produce overtones and true staccato playing is difficult (if not
impossible) to perform on it. The instrument has a distinctive tone all
its own; with an inclination to ""wiriness."
There is no "standard" stringing for the
zither banjo but the following sets of banjo strings are used :-
(1) Plain wire plated 1st, 2nd and 5th.
Nylon-filament 3rd. Nylon-covered 4th.
(2) As above but with a silk-covered 4th.
(3) Plain wire plated 1st, 2nd and 5th. Wire-covered
3rd and 4th.
(4) As (3) but with nylon-covered or silk-covered
4th.
