OCTAVE KEY SYSTEM FOR BASSOON FAMILY OF INSTRUMENTS

Abstract

The present disclosure provides improved octave key systems for use with (e.g., incorporation into) an instrument in the bassoon family.

Description

FIELD

The present disclosure provides improved octave key systems for use with (e.g., incorporation into) an instrument in the bassoon family.

BACKGROUND

Instruments in the bassoon family are capable of emitting pitches across a wide musical range. However, that flexibility also lends the instrument to intonation issues-one tube of fixed length cannot possibly accommodate stable standing waves of precise and consistent pitch without complicated means for precisely adjusting those standing waves.

In the 20th century, the Weisberg System (FIG. 1) was developed to address certain intonation issues for bassoon instruments. While this system dramatically improves intonation of many commonly required musical pitches, the Weisberg System is complicated and requires a large number of intricate and precisely installed keys, rods, bridges, and pads accompanying holes.

A need persists for improved octave key systems for instruments in the bassoon family. The present disclosure satisfies this need.

SUMMARY

In one embodiment, the present disclosure provides an improved octave system for a bassoon instrument, the improved octave system comprising: a vent nib 200 disposed through a side wall 20w of a wing joint component 20 of the musical instrument; and a thumb-actuated octave key 100 comprising: a thumb key 12a, and a whisper key pad 18 and a sealing pad 112 each operatively connected to the thumb pad 12a by one or more rods and bridges 14-17, wherein the whisper key pad 18 is disposed to seal a bocal nub hole 18a disposed on a bocal B when the thumb key 12a is actuated, and wherein the sealing pad 112 is disposed to seal the vent nib 200 when the thumb key 12a is actuated.

DETAILED DESCRIPTION

Prior art octave systems 10, such as the Weisberg System shown specifically in FIG. 1, require a complex network of thumb keys 12 and locks 13 configured to control various pads. The multitude of controls are designed to improve intonation of the instrument's pitch within various subranges of the typical playing ranges of Bb1 to F5 (for a standard bassoon) or Bb0 or A0 to D4 (for a contrabassoon).

Referring generally to FIGS. 2-12, the present disclosure provides improved octave key systems for use with (e.g., incorporation into) a musical instrument in the bassoon family, such as a bassoon or a contrabassoon. Octave key systems consistent with the present disclosure feature a dramatically reduced number of controls compared to prior art octave key systems.

In general, octave systems 100 for a bassoon instrument consistent with the present disclosure include a vent nib 200 disposed on a wing joint 20 of the instrument in operable communication with a thumb key 12a via a sealing pad 112. In operation, actuation of the thumb key 12a causes the sealing pad 112 to seal (e.g., partially seal or completely seal) the vent nib 200 to change a standing wave resonating within a bore 24 of the wing joint 20.

Generally, the octave key system 100 is configured such that the vent nib 200 is unsealed (e.g., is in an open configuration) until the thumb key 12a is activated. In some embodiments, the octave key system 100 is configured such that the vent nib 200 and the bocal nub vent 18a are both unsealed (e.g., are both in open configurations) until the thumb key 12a is activated. In these embodiments, the vent nib 200 and/or the bocal nub vent 18a remain in a closed configuration (e.g., remain sealed) as long as the thumb key 12a is held in an activated position (e.g., is pressed towards the surface of the wing joint 20), and transitions to an open configuration when the thumb key 12a is released.

In some embodiments, the sealing pad 112 includes a natural or synthetic resilient pad, such as white leather, that engages the outer surface 215 of the vent nib 200 when the thumb key 12a is activated.

The sealing pad 112 is in operable communication with the thumb key 12a by one or more rods and bridges 14-17. The exact number and configuration of the rods and bridges 14-17 may vary depending on the other features present on the particular bassoon instrument of interest. In the example specifically shown in FIG. 2, the sealing pad 112 is disposed on the same rod 17 as the whisper key pad 18; two bridges 15-16 connect the rod 17 to an intermediate rod 14 upon which the thumb key 12a is disposed. Actuation of the thumb key 12a causes the rod 17 to rotate sufficiently for the sealing pad 112 to contact the outer surface 215 of the vent nib 200 and for the whisper key 18 to contact the outer surface of the bocal nub vent 18a.

Referring now to FIGS. 3-7 and 12, the vent nib 200 may adopt one of several configurations. Generally, the vent nib 200 includes an external component 210 having a curved outer surface 215 configured to temporarily mate with the sealing pad 112 to seal the bore 230 of the vent nib 200. The vent nib 200 also includes an internal component 220 configured to mate permanently with a bore 25 disposed through the side wall 20w of the wing joint 20 of the bassoon. In some embodiments, the minor diameter d_i of the internal component 220 is slightly smaller than the major diameter d_o of the external component 210 such that a shoulder 211 is formed between the external component 210 and the internal component 220. The shoulder 211 may improve purchase of the vent nib 200 within the wing joint side wall 20w, for example to prevent installation of the vent nib 200 too deeply or too shallowly within the side wall 20w.

In some embodiments, the major diameter d_o of the external component 210 is about 3.0 mm to about 4.0 mm, for example 3.0 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm, or 4.0 mm.

In some embodiments, the minor diameter d_i of the internal component 220 is about 2.8 mm to about 3.8 mm, for example 2.8 mm, 2.9 mm, 3.0 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.6 mm, 3.7 mm, or 3.8 mm.

In some embodiments, the minor diameter d_i of the internal component 220 is about 0.15 mm to about 0.25 mm smaller than the major diameter d_o of the external component 210. For example and without limitation, the minor diameter d_i of the internal component 220 may be 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, 0.20 mm, 0.21 mm, 0.22 mm, 0.23 mm, 0.24 mm, or 0.25 mm smaller than the major diameter d_o of the external component 210.

The bore 230 extends the entire length L of the vent nib 200 such that, after installation in a side wall 20w of a wing joint 20, the inner bore 24 of the wing joint 20 is in fluid communication with the external atmosphere around the wing joint 20 via the bore 230.

The bore 230 in some embodiments includes a first cylindrical bore portion 230a having a bore size b_o at the outermost tip 212 of the vent nib 200. The bore size b_o of the cylindrical bore portion 230a is generally about 0.6 mm to about 0.9 mm, for example 0.60 mm, 0.61 mm, 0.62 mm, 0.63 mm, 0.64 mm, 0.65 mm, 0.66 mm, 0.67 mm, 0.68 mm, 0.69 mm, 0.70 mm, 0.71 mm, 0.72 mm, 0.73 mm, 0.74 mm, 0.75 mm, 0.76 mm, 0.77 mm, 0.78 mm, 0.79 mm, 0.80 mm, 0.81 mm, 0.82 mm, 0.83 mm, 0.84 mm, 0.85 mm, 0.86 mm, 0.87 mm, 0.88 mm, 0.89 mm, or 0.90 mm.

In some embodiments, the cylindrical bore portion 230a extends the entire length L of the vent nib 200, such that the bore size b_o at the outermost tip 212 and the bore size b_o at the innermost point 222 is the same.

In other embodiments, the cylindrical bore portion 230a extends only a portion of the overall length L of the vent nib 200, with the bore 230 further comprising a second bore portion 230b extending from the inner edge of the cylindrical bore portion 230a to the innermost edge 222 of the vent nib 200. In such embodiments, the cylindrical bore 230a may extend into the bore 230 from the outermost tip 212 a length Le of about 1 mm to about 3 mm from the outermost tip 212, such as 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2.0 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, or 3.0 mm.

The second bore portion 230b includes at least one second bore size b_i, and may be cylindrical, tapered, curved (e.g., parabolic), arcuate, or stepped. In some embodiments the second bore portion 230b extends the entire length L of the bore 230. In other embodiments, the second bore portion 230b extends a length Li from the innermost end 222 only a portion of the overall length L of the bore 230. In such embodiments, the second bore portion 230b may extend a length Li from the innermost end 222 of about 5.5 mm to about 9 mm, for example 5.5 mm, 5.6 mm, 5.7 mm, 5.8 mm, 5.9 mm, 6 mm, 6.1 mm, 6.2 mm, 6.3 mm, 6.4 mm, 6.5 mm, 6.6 mm, 6.7 mm, 6.8 mm, 6.9 mm, 7 mm, 7.1 mm, 7.2 mm, 7.3 mm, 7.4 mm, 7.5 mm, 7.6 mm, 7.7 mm, 7.8 mm, 7.9 mm, 8 mm, 8.1 mm, 8.2 mm, 8.3 mm, 8.4 mm, 8.5 mm, 8.6 mm, 8.7 mm, 8.8 mm, 8.9 mm, or 9.0 mm.

The second bore portion 230b includes a bore size b_i at the innermost end 222 that is the same as or larger than the bore size b_o at the outermost tip 212. Generally, the bore size b_i can be about 0.6 mm to about 2.5 mm, for example 0.60 mm, 0.61 mm, 0.62 mm, 0.63 mm, 0.64 mm, 0.65 mm, 0.66 mm, 0.67 mm, 0.68 mm, 0.69 mm, 0.70 mm, 0.71 mm, 0.72 mm, 0.73 mm, 0.74 mm, 0.75 mm, 0.76 mm, 0.77 mm, 0.78 mm, 0.79 mm, 0.80 mm, 0.81 mm, 0.82 mm, 0.83 mm, 0.84 mm, 0.85 mm, 0.86 mm, 0.87 mm, 0.88 mm, 0.89 mm, 0.90 mm, 0.91 mm, 0.92 mm, 0.93 mm, 0.94 mm, 0.95 mm, 0.96 mm, 0.97 mm, 0.98 mm, 0.99 mm, 1.00 mm, 1.01 mm, 1.02 mm, 1.03 mm, 1.04 mm, 1.05 mm, 1.06 mm, 1.07 mm, 1.08 mm, 1.09 mm, 1.10 mm, 1.11 mm, 1.12 mm, 1.13 mm, 1.14 mm, 1.15 mm, 1.16 mm, 1.17 mm, 1.18 mm, 1.19 mm, 1.20 mm, 1.21 mm, 1.22 mm, 1.23 mm, 1.24 mm, 1.25 mm, 1.26 mm, 1.27 mm, 1.28 mm, 1.29 mm, 1.30 mm, 1.31 mm, 1.32 mm, 1.33 mm, 1.34 mm, 1.35 mm, 1.36 mm, 1.37 mm, 1.38 mm, 1.39 mm, 1.40 mm, 1.41 mm, 1.42 mm, 1.43 mm, 1.44 mm, 1.45 mm, 1.46 mm, 1.47 mm, 1.48 mm, 1.49 mm, 1.50 mm, 1.51 mm, 1.52 mm, 1.53 mm, 1.54 mm, 1.55 mm, 1.56 mm, 1.57 mm, 1.58 mm, 1.59 mm, 1.60 mm, 1.61 mm, 1.62 mm, 1.63 mm, 1.64 mm, 1.65 mm, 1.66 mm, 1.67 mm, 1.68 mm, 1.69 mm, 1.70 mm, 1.71 mm, 1.72 mm, 1.73 mm, 1.74 mm, 1.75 mm, 1.76 mm, 1.77 mm, 1.78 mm, 1.79 mm, 1.80 mm, 1.81 mm, 1.82 mm, 1.83 mm, 1.84 mm, 1.85 mm, 1.86 mm, 1.87 mm, 1.88 mm, 1.89 mm, 1.90 mm, 1.91 mm, 1.92 mm, 1.93 mm, 1.94 mm, 1.95 mm, 1.96 mm, 1.97 mm, 1.98 mm, 1.99 mm, 2.00 mm, 2.01 mm, 2.02 mm, 2.03 mm, 2.04 mm, 2.05 mm, 2.06 mm, 2.07 mm, 2.08 mm, 2.09 mm, 2.10 mm, 2.11 mm, 2.12 mm, 2.13 mm, 2.14 mm, 2.15 mm, 2.16 mm, 2.17 mm, 2.18 mm, 2.19 mm, 2.20 mm, 2.21 mm, 2.22 mm, 2.23 mm, 2.24 mm, 2.25 mm, 2.26 mm, 2.27 mm, 2.28 mm, 2.29 mm, 2.30 mm, 2.31 mm, 2.32 mm, 2.33 mm, 2.34 mm, 2.35 mm, 2.36 mm, 2.37 mm, 2.38 mm, 2.39 mm, 2.40 mm, 2.41 mm, 2.42 mm, 2.43 mm, 2.44 mm, 2.45 mm, 2.46 mm, 2.47 mm, 2.48 mm, 2.49 mm, or 2.50 mm. In one specific example, the bore size b_i is about 2.0-2.1 mm, or about 2.08 mm.

In some embodiments, such as those consistent with the example specifically illustrated in FIGS. 4-5, the bore 230 is curved along all or substantially all of the length L from the outermost tip 212 to the innermost end 222. For example and without limitation, FIG. 4 shows one specific embodiment including a bore 230 that includes a cylindrical bore portion 230a disposed towards the outermost tip 212, and a curved bore portion 230b disposed towards the innermost end 222. In this specific embodiment, the curved bore portion 230b has a relatively smaller bore b_o at its medial end 232 and a relatively larger bore b_i at its innermost end 222. In the embodiment specifically shown in FIG. 5, the bore 230 includes a curved surface 225 along its entire length from the outermost tip 212 to the innermost end 222. The curve of the inner surface 225 of the bore 230 may be defined by any curve equation, such as radial, sinusoidal, parabolic, etc. In some embodiments, the inner surface 225 or a portion thereof is parabolic.

In some embodiments, the bore 230 or a portion thereof includes a frustoconical shape. Generally, the frustoconical bore or portion thereof is oriented such that it includes a relatively smaller bore b_o disposed towards the outermost tip 212 and a relatively larger bore b_i disposed towards the innermost end 222. For example and without limitation, the embodiments specifically shown in FIGS. 3 and 6 each include a frustoconical bore or bore portion. In the embodiment specifically illustrated in FIG. 3, the bore 230 includes a cylindrical bore portion 230a disposed towards the outermost tip 212, and a frustoconical bore portion 230b disposed towards the innermost end 222. In the embodiment specifically shown in FIG. 6, the bore 230 includes an inner surface 225 that is frustoconical in shape along the entire length L of the bore 230, with a relatively smaller bore b_o disposed at the outermost tip 212 and a relatively larger bore b_i disposed at the innermost end 222.

In some embodiments, the bore 230 or a portion thereof includes a plurality of discrete bore diameters b_o, b_i, b_i2, b_i3, b_i4, etc. Each successive bore diameter, viewed from outermost tip 212 to innermost end 222, may be slightly larger than the previous bore diameter such that the inner surface 225 of the bore 230 appears stepped. Each bore diameter b_o, b_i, b_i2, b_i3, b_i4, etc. may be independently selected from the group consisting of: 0.60 mm, 0.61 mm, 0.62 mm, 0.63 mm, 0.64 mm, 0.65 mm, 0.66 mm, 0.67 mm, 0.68 mm, 0.69 mm, 0.70 mm, 0.71 mm, 0.72 mm, 0.73 mm, 0.74 mm, 0.75 mm, 0.76 mm, 0.77 mm, 0.78 mm, 0.79 mm, 0.80 mm, 0.81 mm, 0.82 mm, 0.83 mm, 0.84 mm, 0.85 mm, 0.86 mm, 0.87 mm, 0.88 mm, 0.89 mm, 0.90 mm, 0.91 mm, 0.92 mm, 0.93 mm, 0.94 mm, 0.95 mm, 0.96 mm, 0.97 mm, 0.98 mm, 0.99 mm, 1.00 mm, 1.01 mm, 1.02 mm, 1.03 mm, 1.04 mm, 1.05 mm, 1.06 mm, 1.07 mm, 1.08 mm, 1.09 mm, 1.10 mm, 1.11 mm, 1.12 mm, 1.13 mm, 1.14 mm, 1.15 mm, 1.16 mm, 1.17 mm, 1.18 mm, 1.19 mm, 1.20 mm, 1.21 mm, 1.22 mm, 1.23 mm, 1.24 mm, 1.25 mm, 1.26 mm, 1.27 mm, 1.28 mm, 1.29 mm, 1.30 mm, 1.31 mm, 1.32 mm, 1.33 mm, 1.34 mm, 1.35 mm, 1.36 mm, 1.37 mm, 1.38 mm, 1.39 mm, 1.40 mm, 1.41 mm, 1.42 mm, 1.43 mm, 1.44 mm, 1.45 mm, 1.46 mm, 1.47 mm, 1.48 mm, 1.49 mm, 1.50 mm, 1.51 mm, 1.52 mm, 1.53 mm, 1.54 mm, 1.55 mm, 1.56 mm, 1.57 mm, 1.58 mm, 1.59 mm, 1.60 mm, 1.61 mm, 1.62 mm, 1.63 mm, 1.64 mm, 1.65 mm, 1.66 mm, 1.67 mm, 1.68 mm, 1.69 mm, 1.70 mm, 1.71 mm, 1.72 mm, 1.73 mm, 1.74 mm, 1.75 mm, 1.76 mm, 1.77 mm, 1.78 mm, 1.79 mm, 1.80 mm, 1.81 mm, 1.82 mm, 1.83 mm, 1.84 mm, 1.85 mm, 1.86 mm, 1.87 mm, 1.88 mm, 1.89 mm, 1.90 mm, 1.91 mm, 1.92 mm, 1.93 mm, 1.94 mm, 1.95 mm, 1.96 mm, 1.97 mm, 1.98 mm, 1.99 mm, 2.00 mm, 2.01 mm, 2.02 mm, 2.03 mm, 2.04 mm, 2.05 mm, 2.06 mm, 2.07 mm, 2.08 mm, 2.09 mm, 2.10 mm, 2.11 mm, 2.12 mm, 2.13 mm, 2.14 mm, 2.15 mm, 2.16 mm, 2.17 mm, 2.18 mm, 2.19 mm, 2.20 mm, 2.21 mm, 2.22 mm, 2.23 mm, 2.24 mm, 2.25 mm, 2.26 mm, 2.27 mm, 2.28 mm, 2.29 mm, 2.30 mm, 2.31 mm, 2.32 mm, 2.33 mm, 2.34 mm, 2.35 mm, 2.36 mm, 2.37 mm, 2.38 mm, 2.39 mm, 2.40 mm, 2.41 mm, 2.42 mm, 2.43 mm, 2.44 mm, 2.45 mm, 2.46 mm, 2.47 mm, 2.48 mm, 2.49 mm, or 2.50 mm.

The vent nib 200 is disposed between the C vent CV and the A vent AV of the bassoon's wing joint 20. The exact location of the vent nib 200 may vary slightly from bassoon to bassoon, but generally is located about 2.5-3.5 cm below the C vent CV, and about 2.5-3.5 cm above the A vent AV. In one non-limiting example, the centerline 25_CL of the vent nib 200 is located 2.5-3.5 cm, or about 2.75-3.0 cm, below the centerline CV_CL of the C vent CV, and about 2.5-3.5 cm, or about 2.75-3.25 cm, above the centerline AV_CL of the A vent AV.

The improved octave key systems 100 of the present disclosure may be installed as original components on a bassoon. In other embodiments, the improved octave key systems 100 of the present disclosure may be installed on an already-manufactured bassoon. To install an improved octave system 100, a hole 25 sized approximately the same diameter as the minor diameter d_i of the internal component 220 of the vent nib 200 is made through the side wall 20w of the wing joint. The hole 25 is made approximately 2.5-3.5 cm below the C vent CV, for example 2.5 cm, 2.55 cm, 2.6 cm, 2.65 cm, 2.7 cm, 2.75 cm, 2.8 cm, 2.85 cm, 2.9 cm, 2.95 cm, 3 cm, 3.05 cm, 3.1 cm, 3.15 cm, 3.2 cm, 3.25 cm, 3.3 cm, 3.35 cm, 3.4 cm, 3.45 cm, or 3.5 cm below the C vent CV. In some embodiments, the hole 25 is disposed approximately 2.5-3.5 cm above the A vent AV, for example 2.5 cm, 2.55 cm, 2.6 cm, 2.65 cm, 2.7 cm, 2.75 cm, 2.8 cm, 2.85 cm, 2.9 cm, 2.95 cm, 3 cm, 3.05 cm, 3.1 cm, 3.15 cm, 3.2 cm, 3.25 cm, 3.3 cm, 3.35 cm, 3.4 cm, 3.45 cm, or 3.5 cm above the A vent AV. The position of the hole 25 may be determined by measuring, for example, from the centerline CV_CL of the C vent CV, and/or from the centerline AV_CL of the A vent AV. A vent nib 200 is then inserted into the hole 25. An adhesive may optionally be used to secure the vent nib 200 in the hole 25.

A sealing pad 112 is attached to a rod 17 in operative communication with the thumb key 12a, for example the same rod 17 that also includes the whisper key 18 for mating with the bocal nub 18a. A bridge 14 may be disposed between the rod 17 and the sealing pad 112 if necessary. Installation is complete when actuation of the thumb key 12a causes the sealing pad 112 to engage with the outer surface 215 of the vent nib 200, and when release of the thumb key 12a causes the sealing pad 112 to disengage from the surface 215 of the vent nib 200.

In some embodiments, the present disclosure provides an improved octave system for a bassoon instrument, the improved octave system comprising: a vent nib 200 disposed through a side wall 20w of a wing joint component 20 of the musical instrument; and a thumb-actuated octave key 100 comprising: a thumb key 12a, and a whisper key pad 18 and a sealing pad 112 each operatively connected to the thumb pad 12a by one or more rods and bridges 14-17, wherein the whisper key pad 18 is disposed to seal a bocal nub vent 18a disposed on a bocal B when the thumb key 12a is actuated, and wherein the sealing pad 112 is disposed to seal the vent nib 200 when the thumb key 12a is actuated. In some embodiments, the whisper key pad 18 and the sealing pad 112 are each disposed on a single rod 17 in operative communication with the thumb key 12a. In some embodiments, the sealing pad 112 is disposed a predetermined distance 25-CV below a C vent CV of the bassoon. In some embodiments, the improved octave system further comprises a bridge 15 in operative communication between the single rod 17 and the thumb key 12a. In some embodiments, the improved octave system further comprises a second rod 14 disposed in operative communication between the bridge 15 and the thumb key 12a. In some embodiments, the vent nib 200 includes a rounded outer contour 215 configured to engage the sealing pad 112.
