STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
(Not Applicable).
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the modulation of tone and wavelength, and
producing other effects, manually, on either acoustic or electric stringed
instruments, particularly on guitars, by the use of a manual "slide" or
"steel".
2. Description of the Related Art
(Not Applicable).
BRIEF SUMMARY OF THE INVENTION
Whereas manual slides are commonly used on guitars, they are used in
conjunction with the fingering hand of the player on the finger board or
neck of the guitar, to contact the strings in appropriate locations for
selecting the notes to be played. In accordance with the present
invention, however, the manual slide is used on the strumming or picking
hand of the guitar player, and it is positioned adjacent and in front of
the bridge of the guitar. This enables the player to introduce a vibrato
or tremolo, or otherwise to affect the voice and texture and wave
properties of the notes being played, or to introduce other effects. These
effects are facilitated by the fact that the slide is manipulated by the
strumming hand, independently of the fingering action and note selection,
and movement or oscillation of the slide over the strings toward and away
from the bridge, has a direct effect on the length of the string(s)
subject to strumming or picking vibration. The present invention enables
one to obtain in an entirely manual instrument, many of the effects that
have heretofore been limited to auxiliary mechanical and electrical
devices, giving the musician much greater expressive control of the music
being produced.
Since in the practice of the present invention the slide is associated with
the picking or strumming hand, the fingering hand can function without
restriction, allowing it to perform all manipulations previously made in
normal guitar playing. Furthermore, since the slide is positioned to hover
directly above or in close proximity to the bridge, subtle effects
resulting from the controlled contact of the slide with the strings, such
as buzz, vibration, and wavelength modulation, which would be inaudible or
too quiet to be of any value if created by use of a slide elsewhere on the
instrument, become audible and controllable, because of the immediate
proximity to the bridge.
Also, because the slide is being used adjacent to the bridge of the
stringed instrument, it is desirable that the bridge be designed to
accommodate the use of the slide. First, it is most desirable that the
bridge support the strings in a straight line, or lying in a flat plane,
particularly in the direction transverse to the length dimension of the
strings, or across the guitar, so that the slide can contact all strings
simultaneously. Second, it is important that the slide not contact the
bridge per se, to avoid any such contact sounds. To this end, it is
desirable that each string rest on the top of an individual bridge
pinnacle, with the bridge recessed into valleys between pinnacles.
Further, it is desirable that any portions of the bridge extending beyond
the first and last strings be cut back below the level of the strings.
It is accordingly one object of the present invention to provide musical
effects in a stringed instrument, by use of a manual slide adjacent to the
bridge of the instrument.
Another object of the present invention is to provide musical effects in a
guitar, by use of a manual slide adjacent to the bridge.
A further object of the present invention is to provide musical effects in
a stringed instrument, such as a guitar, by use of a manual slide adjacent
to the bridge of the instrument, wherein the bridge is designed to
accommodate the slide and to avoid contact between the slide and the
bridge.
Other objects and advantages of the present invention will become apparent
to those skilled in the art from a consideration of the following detailed
description of the invention, had in conjunction with the accompanying
drawings, in which like numerals refer to like or corresponding parts, and
wherein:

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1 and 2, the slide 10 contains two primary parts, the
rod 11 and finger ring 12. The rod is preferably made of steel or brass
for the best tone effects. The ring 12 is assembled to the rod 11 by means
of a post 13 attached to the ring, and the post fits into the diametric
hole 14 in the rod. A retaining screw 15 with a knurled head 16 is
threaded into the threaded axial hole or receptacle 17 in the rod. When
the ring post 13 is inserted into hole 14 and the retaining screw 15 is
fully threaded into its threaded receptacle 17, its conical end 18 enters
the circumferential groove 19 near the end of post 13, thus retaining the
ring and post mounted on the rod 11. However, while the screw 15 is
designed to retain the ring 12 and post 13 assembled to the rod 11, it
does not necessarily clamp the ring post, leaving the ring 12 free to
swivel about the axis of the hole 14, while being retained in assembled
relation with the rod 11. Obviously, the screw 15 can clamp the ring 12
and post 13 in a fixed position relative to rod 11, if desired.
In use, the musician inserts the little finger of his or her strumming hand
into the ring, as indicated in FIGS. 2 and 4. In this way, the playing
fingers are positioned and are free to pick or strum the strings, while
the slide 10 is positioned and moved along the strings adjacent the
bridge, as desired by the musician, and as indicated in FIG. 4.
Turning next to the bridge 30, it is illustrated in FIGS. 3, 4 and 5. The
preferred form of bridge 30 comprises a series of notched pinnacles 31
(shown as six, to receive six guitar strings), separated by a series of
intervening valleys 32. The pinnacles are arranged to lie in a straight
line, so that the musical strings, when placed in the notches and drawn
taught over the bridge, all lie in a flat plane adjacent the bridge in the
area toward the fingering or fret board of the guitar. Thus, the slide rod
11 is able to contact all the strings simultaneously, as shown in FIG. 4.
In addition, the ends of the bridge beyond the strings on each side, are
also recessed, as shown at 33. This structure permits the slide to remain
in contact with the strings adjacent to the bridge at all times, without
suffering contact with the bridge. Were the latter to occur, the contact
noise would have a disturbing effect on the musical sound. Similarly, a
leather, felt or other cover may be placed over the string anchorages 35
behind the bridge, when closely adjacent to the bridge 30.
Thus, as illustrated in FIGS. 2 and 4, the musician mounts the slide on the
strumming or picking hand by inserting the little finger into the ring 12,
leaving the playing fingers in position and free to strum or pick in the
usual manner. While the musician strums or picks the strings of the
guitar, the slide is placed across the strings adjacent to the bridge and
the slide is oscillated lengthwise along the strings to create a vibrato
or tremolo effect, or other analogous variation in the tonal quality, as
desired by the musician.
As is apparent from the foregoing description, different size rings 12 many
be mounted on a given rod 11, as required or desired. And if desired, the
ring 12 may be lined with leather, fabric or a cushioning material.
Likewise, a given size ring 12 may be mounted on various rods, either of
different size, different material, or different structure.
Other modifications and variations of the invention will be perceived, and
such as are embraced by the spirit and scope of the appended claims are
contemplated as being within the purview of the present invention.
