Description

BACKGROUND

Technical Field

This disclosure generally relates to musical instruments. More specifically, the present disclosure relates to string instruments with superior tonal qualities.

Related Technology

Classical string instruments, such as violins, violas, cellos, and basses have been produced by artisan craftsmen for centuries. The sound produced by string instruments is a result of the interactions between each instrument's various parts. When a string of the instrument vibrates, that vibration resonates through the bridge and sound post, passing into the hollow body of the instrument to allow the sound to resonate into the surrounding air. The quality of such sound depends significantly on the tension produced by the various parts of the string instrument. Some string instruments are unable to produce a smooth, vibrant sound due to poor construction or design of the various components of the instrument.

Artisan-crafted classical string instruments are well known for their superior sound quality because each instrument is meticulously crafted to ensure a construction capable of producing a balanced and robust tonal spectrum. Variations in the construction of each instrument have traditionally been necessary to ensure the ideal tension is produced by the completed violin in order to achieve a robust, clear, and powerful tone. Production of classical string instruments with optimum tonal qualities, therefore, has generally proven to be difficult, laborious, and expensive.

Accordingly, there are a number of disadvantages with classical string instruments that can be addressed.

BRIEF SUMMARY

Implementations of the present disclosure solve one or more of the foregoing or other problems in the art with string instruments having superior tonal qualities. In particular, one or more implementations can include a string instrument is disclosed having a body with an air cavity defined by a top plate, a bottom plate, and one or more ribs, a bass bar being secured to an inside surface of the top plate, the bass bar comprising a layup of a plurality of laminates constructed from western red cedar and comprising particular dimensions and placement on the top plate relative to the length of the instrument body.

String instruments with superior tonal qualities of the present disclosure can also include a bass bar having a length such that the ratio of the length of the bass bar to the length of the string instrument body is approximately four to seven.

DETAILED DESCRIPTION

Before describing various embodiments of the present disclosure in detail, it is to be understood that this disclosure is not limited to the parameters of the particularly exemplified systems, methods, apparatus, products, processes, and/or kits, which may, of course, vary. Thus, while certain embodiments of the present disclosure will be described in detail, with reference to specific configurations, parameters, components, elements, etc., the descriptions are illustrative and are not to be construed as limiting the scope of the claimed invention. In addition, the terminology used herein is for the purpose of describing the embodiments and is not necessarily intended to limit the scope of the claimed invention.

In addition, unless otherwise indicated, numbers expressing quantities, constituents, distances, or other measurements used in the specification and claims are to be understood as being modified by the term “about,” as that term is defined herein. Accordingly, unless indicated to the contrary, the numerical parameters set forth in the specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the subject matter presented herein. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the subject matter presented herein are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical values, however, inherently contain certain errors necessarily resulting from the standard deviation found in their respective testing measurements.

The terms “approximately,” “about,” and “substantially” as used herein represent an amount or condition close to the stated amount or condition that still performs a desired function or achieves a desired result. For example, the terms “approximately,” “about,” and “substantially” may refer to an amount or condition that deviates by less than 10%, or by less than 5%, or by less than 1%, or by less than 0.1%, or by less than 0.01% from a stated amount or condition.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure pertains.

Embodiments of the present disclosure enable a maker of string instruments or luthier to consistently construct string instruments capable of producing sound with superior tonal qualities. For example, string instruments of the present disclosure exhibit improvements over currently available string instruments in terms of power, playability, tonal balance, dynamic range, vibrato, intonation of double-stopped fifths, and various other aspects generally sought after by musicians and players of string instruments. Further, string instruments according to the present disclosure exhibit the power, range, and balance necessary to be played alongside a grand piano, with the lid of the piano fully raised, without being overpowered or muted by the sound of the grand piano. Further still, while some presently available string instruments are indeed capable of exceptional tonal qualities in the hands of a highly trained musician exhibiting exceptional finesse and skill, string instruments of the present disclosure are capable of producing superior tonal qualities with relative ease by musicians of moderate skill.

Moreover, string instruments according to the present disclosure can be played gently with finesse or more aggressively while producing the superior tonal qualities with either style of playing. The design and construction of previously available string instruments did not produce superior tonal qualities when played in both styles (gentle/finesse vs. aggressive). At best, previously available string instruments would produce superior tonal qualities only when played in one style or the other, but not both. For instance, many Stradivarius violins have to be played more gently or with more finesse in order to produce high quality sounds. If such instruments are played more aggressively, the quality of the produced sounds diminished dramatically. In contrast, other types of previously produced violins could produce high quality sound when played more aggressively, but not when played gently or with finesse. Thus, the string instruments of the present disclosure allow for a player to employ whichever style he/she desires or is required for a particular piece of music, while still producing superior tonal qualities that are not diminished by playing in one style or the other.

In particular, the methods, materials, and construction of various components of string instruments with superior tonal qualities are disclosed.

Embodiments of the present disclosure include string instruments having a body with an air cavity defined by a top plate, a bottom plate, and one or more ribs, a bass bar being secured to an inside surface of the top plate, the bass bar comprising a layup of a plurality of laminates constructed from western red cedar and comprising particular dimensions and placement on the top plate relative to the length of the instrument body.

Embodiments disclosed herein include multiple ratios that can be applied to string instruments of various dimensions and sizes to improve the tonal qualities and other qualities of each string instrument. In some embodiments, for example, a violin of classical dimensions and construction is improved by the incorporation of a bass bar that is constructed and installed according to the present disclosure. Some embodiments comprise differing sizes of violins, such as but not limited to 1/4, 2/4, 3/4, and 4/4, as well as all sizes of violas, cellos, basses, and other string instrument designs. One should appreciate that the present disclosure may be applied to any string instrument design to achieve superior tonal qualities.

While the drawings accompanying this disclosure focus in part on a violin for convenience and consistency, the disclosed materials, constructions, ratios, and dimensions can be applied to different string instruments without a loss of tonal qualities.

Referring to FIG. 1, some embodiments of a string instrument 100 comprise a body 110 having an air cavity 112, body 110 being formed by a top plate 114 and a back plate 116 being secured to one or more ribs 118 to form air cavity 112 therebetween. As illustrated, one or more f-holes 120 are cut into top plate 114 of some embodiments, thus creating an opening through which sound may pass from within air cavity 112. Additionally, some embodiments include a neck 122 attached to and extending away from an upper end of body 110, neck 122 having a fingerboard 124 thereon or attached thereto, as well as a tailpiece 126 attached to a lower end of body 110 and a plurality of strings 128 coupled between tailpiece 126 and a distal end of neck 122. Also as illustrated, some embodiments include a bridge 130 associated with top plate 114 proximate f-holes 120 and configured to support strings 128 above fingerboard 124.

As illustrated in FIGS. 2A through 2C, some embodiments of the present disclosure include a bass bar 200 comprising particular dimensions relative to the size of the string instrument to which bass bar 200 is to be secured. For example, as shown in FIG. 2A, bass bar 200 has a length (x) between a first end 208 and a second end 210, and a height profile wherein the maximum height of bass bar 200 occurs at a particular distance (a) from a first end 208, and wherein the height of bass bar 200 gradually reduces along the length of bass bar 200 in either direction along its length to reach an minimum height at respective first end 208 and second end 210. In other words, bass bar 200 has a minimum height at first end 208, a height at second end 210 that is substantially equal to that of first end 208, and a maximum height at a point along the length of bass bar 200 at distance (a) from first end 208. In some embodiments, the ratio of distance (a) to the length (x) of bass bar 200 is approximately five to eight.

In some embodiments, the minimum thickness of bass bar 200 is approximately ¼ inch and the maximum thickness is approximately ½ inch. As further discussed in relation to FIG. 3 below, one or more embodiments of a string instrument having a 14-inch body according to the present disclosure comprise a bass bar 200 having a length (x) of approximately 8 inches, and a maximum thickness located a distance (a) approximately 5 inches from first end 208.

Also shown in FIG. 2A, some embodiments comprise a bass bar 200 that is cut from a wooden material such that the grain direction 206 is substantially parallel to the length (x) or longitudinal axis of bass bar 200. Also, some embodiments include chamfered edges at first end 208 and second end 210, as well as a tapered height profile from the minimum height at first end 208 to the maximum height (h) at distance (a) from first end 208 to the minimum height again at second end 210. Further, some embodiments comprise a lower edge 212 that is configured to conform with an inner surface of top plate 114 (see FIGS. 1 and 3).

In some embodiments, the ratio of maximum height (h) to length (x) is approximately three to sixty-four, the ratio of the height proximate to first end 208 to the maximum height (h) is approximately one to two, the height proximate to second end 208 is approximately equal to the height proximate to second end 210, and the ratio of a width of the bass bar to the length (x) is approximately one to thirty-two. In at least one embodiment, for example, bass bar 200 is sanded to a width of approximately ¼ inch, a height of approximately 3/16 inch at the first end and the second end, and a maximum height (h) of ⅜ inch.

FIG. 2B illustrates a bottom view of a layup 202 of multiple laminates 204 from which some embodiments of bass bar 200 is cut. In particular, some embodiments comprise layup 202 prepared from a plurality of laminates 204 pressed together with a layer of adhesive, each laminate 204 cut from western red cedar, such that the grain direction runs substantially parallel to the longitudinal axis of each laminate 204. In some embodiments, western red cedar split rails or posts are used for their consistent grain direction 206 as a result of the process by which the split rails and posts are cut from western red cedar trees; however, any timber, lumber, log or the like of western red cedar exhibiting a substantially consistent grain direction may be used to produce components of the present disclosure.

Each of the plurality of laminates 204 undergo a minimal sanding to ensure a smooth surface, then they are secured to one another with adhesive and pressed together to form layup 202. As depicted in FIG. 2B, some embodiments consist of four laminates 204; however, other embodiments are comprised of more or less than four laminates 204, depending on the desired overall thickness and strength of layup 202. In some embodiments, each laminate 204 is cut to a length approximately two inches greater than length (x) of bass bar 200 (see FIG. 2A), such that an embodiment wherein bass bar 200 is 8 inches long results in laminates 204 of approximately 10 inches in length. Also, some embodiments comprise laminates 204 having a thickness of approximately 1.5 millimeters and a width of approximately one inch. In some embodiments, laminates 204 have a thickness of approximately 0.075 inch.

FIG. 2C illustrates a side view of layup 202 from which bass bar 200 is cut according to some embodiments. As illustrated, the grain direction 206 is substantially parallel to the length or longitudinal axis of layup 202, as well as bass bar 200, resulting in optimum tensile strength of bass bar 200. Further, layup 202 of multiple laminates 204 exhibits a significant increase in tensile strength in comparison to traditional bass bar constructions using a single piece of material, thus allowing for the design of a bass bar 200 that is relatively shorter while simultaneously increasing the overall tension of the string instrument, which in turn improves the tonal qualities of the finished instrument.

As indicated by the broken lines in FIG. 2C, bass bar 200 is cut from layup 202. The lower edge 212 is configured to conform with an inner surface of top plate 114 by use of a contour gauge or similar tool to match lower edge 212 to the corresponding surface. Once bass bar 200 is cut from layup 202, it is sanded and shaped prior to installation. In some embodiments, the profile of bass bar 200 is cut from layup 202 with enlarged dimensions to allow for material to be removed in the sanding process in order to achieve the dimensions as discussed in relation to FIG. 2A.

As illustrated in FIG. 3, some embodiments of a top plate 114 comprise an upper bout 132, a lower bout 134, a waist 136, and two f-holes 120 defined by f-shaped cuts in top plate 114. As shown, top plate 114 has a length (y), which varies depending on the style and size of string instrument. As a non-limiting example, a full-size violin has a top plate 114 with a length (y) of approximately 14 inches. In some embodiments, the ratio of the length (y) of top plate 114 or body 110 to the length (x) of bass bar 200 (see FIG. 2A) is approximately four to seven. Accordingly, the length (x) of bass bar 200 can be calculated by multiplying the length (y) by 4/7.

FIG. 3 also illustrates the placement of bass bar 200 on the back side of top plate 114 according to some embodiments. As illustrated, bass bar 200 is secured to top plate 114 such that first end 208 is proximate a central longitudinal axis of top plate 114 and at a distance (b) from an upper end of top plate 114. In some embodiments, bass bar 200 extends from first end 208 towards second end 210 at an angle (θ) relative to the central longitudinal axis of top plate 114, such that bass bar 200 is separated from one of f-holes 120 by a distance (c). In some embodiments, the ratio of distance (b) to length (y) is approximately three to fourteen. Also, in some embodiments, the ratio of distance (c) to length (x) of bass bar 200 (see FIG. 2A) is approximately one to sixty-four. In some embodiments, bass bar 200 is also separated from a lower end of top plate 114 by a distance approximately equal to distance (b).

As a non-limiting example, a violin having a length (y) of 14 inches, in some embodiments, comprises a bass bar 200 having a length (x) equal to approximately 8 inches, the bass bar 200 being secured to top plate 114 at a distance (b) from an upper end of top plate 114 of approximately 3 inches and a distance (c) from one of f-holes 120 of approximately ⅛ inch. One should appreciate that string instruments having different values of length (y) would result in different values of length (x), distance (b), and distance (c), according to embodiments of the present disclosure.

Referring to FIGS. 4A and 4B, a top plate 114 and a back plate 116 according to some embodiments are illustrated with exemplary tools for measuring thickness. As shown in FIG. 4A, some embodiments include a top plate 114 having an upper bout 132, a lower bout 134, and a waist 136. In some embodiments, such as but not limited to a full-size violin, upper bout 132 has a thickness of approximately 2.0 to 2.5 millimeters, lower bout 134 has a thickness of approximately 2.0 to 2.5 millimeters, and waist 136 has a thickness of approximately 3.0 to 3.5 millimeters. One should appreciate that the disclosed thicknesses and other disclosed dimensions herein may be modified to correspond to different sizes of string instruments.

As shown in FIG. 4B, some embodiments include a back plate 116 having an upper bout 142, a lower bout 144, and a waist 146. In some embodiments, such as but not limited to a full-size violin, upper bout 142 has a thickness of approximately 2.0 to 2.5 millimeters, lower bout 144 has a thickness of approximately 2.0 to 2.5 millimeters, and waist 146 has a thickness of approximately 3.0 to 3.5 millimeters. One should appreciate that the disclosed thicknesses and other disclosed dimensions herein may be modified to correspond to different sizes of string instruments.
