(57) [Abstract] [Problem] There is little variation in blowing feeling and tone color from the high tone range to the low tone range, a glossy tone is obtained in the high tone range, and a large volume is obtained in the low tone range. Make it easy to change. SOLUTION: A thumb rest 6 provided on a tube main body 2 to which a thumb of a left hand is pressed at the time of playing is made of metal such as silver, pure copper, copper alloy, and stainless.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a thumbstrap of a saxophone.

[0002]

[Prior art]

 Conventionally, in this type of saxophone, a thumb pad, which is attached to the outer peripheral surface of the tube body and is held by the thumb of the left hand during playing, is made of synthetic resin. The reason is that it was thought that it could be manufactured at low cost, and that it was small and would not affect the vibration of the pipe body.

[0003]

[Problems to be solved by the invention]

 As described above, it was generally thought that even if the thumb pad was made of synthetic resin, it did not directly affect the vibration of the tube body. The inventor of the present invention played with the material of the thumb table changed, and found that the synthetic resin-made one had a stronger tendency to suppress the vibration of the tube body than the metal-made one. In addition, the synthetic resin thumb fingerboard has a non-uniform blowing feeling of each sound, and there is resistance to the blowing feeling of a specific sound (eg, B, D, F, A sounds) and a feeling that the tones are clogged. And the overall feeling of blowing and the timbre vary. It was also found that the volume of bass sounds tends to be difficult to produce. This is considered to be due to the difference in vibration transmission characteristics due to the material density.

The present invention was made in order to solve the above-mentioned conventional problems, and an object thereof is to obtain a high level of overall feeling of blowing and timbre from the high frequency range to the low frequency range. The purpose of the present invention is to provide a saxophone thumb pad that can obtain a so-called glossy tone in the tone range, a large volume in the low tone range, and can change the tone color.

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention is characterized in that a thumb finger stand, which is attached to an outer peripheral surface of a tube main body and is pressed by a thumb of a left hand during playing, is made of metal. Further, the present invention is characterized in that the metal is any one of silver, pure copper, a copper alloy, and stainless steel.

In the present invention, the thumb pad made of metal has a larger specific gravity than that made of a synthetic resin, and thus has excellent vibration transmission characteristics and does not suppress the vibration of the tube body. For this reason, there is little variation in the feeling of blowing and timbre overall from the high range to the low range, the timbre in the high range is so-called glossy, and a large volume is obtained in the low range. Also, when a metal material is selected, the specific gravity is different, so that the timbre can be subtly changed.

[Embodiment of the invention]

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings. FIG. 1 is a diagram showing a schematic configuration of a saxophone according to the present invention, and FIG. 2 is a sectional view showing a mounting structure of a thumb pad. In these figures, a saxophone 1 includes a tube body 2, a blow tube 3 connected to a proximal end portion of the tube body 2, a mouse piece 4 attached to the blow tube 3, and an outer peripheral surface of the tube body 2. A key mechanism (not shown) for controlling the opening and closing of each sound hole 5 provided on the main body 2 and a thumb rest 6 and a finger rest 7 which are also attached to the outer peripheral surface of the tube body 2 and the like. The tube body 2 is formed of brass, nickel silver, or the like into a J-shaped bent shape, and the tip portion constitutes the morning glory 2A. Thumb platform 6 is provided on the back side of the main pipe 2 to be located near the 19 sound hole 5 _19, the finger hook 7, on the rear side of the main pipe 2 to be located near the 17 sound hole 5 ₁₇ It is provided. In order to play such a saxophone 1, the tube body 2 is held by both hands, and the thumb of the left hand is pressed against the thumb rest 6 to hook the finger of the right hand on the finger rest 7 for playing.

As shown in FIG. 2, the thumb pad 6 is formed in a cylindrical shape having a diameter D of about 25 mmφ and a height H of about 3 mm, and a cylindrical body 11 is integrally provided inside thereof. The tubular body 11 is formed so as to project from the thumbstrap 6, is fitted into a tubular mounting portion 10 projecting from the outer peripheral surface of the tube body 2, and is fixed by an adhesive. As the material of the thumb pad 6 as described above, silver, pure copper, copper alloy (eg brass), stainless steel or the like is used, although it depends on the material of the tube body 2. The thumb pad 6 is plated with gold or the like.

By providing the metal thumb pad 6 as described above, the vibration of the pipe body 2 is good because the vibration transmission characteristics are excellent as compared with the conventional synthetic resin finger pad, and the vibration from the high frequency range is low. There is little overall variation in tone and timbre up to the treble range, and so-called glossy treble in the treble range can be obtained, while a large volume can be obtained in the bass range. It is also possible to change the timbre by selecting the metal material.

[0010]

[Effect of the invention]

 As described above, according to the saxophone thumb finger stand according to the present invention, the thumb finger stand that is attached to the outer peripheral surface of the tube body and is held by the thumb of the left hand when playing is made of metal such as silver, pure copper, copper alloy or stainless steel. Therefore, the vibration of the tube body is good, there is little variation in the feeling of blowing and timbre overall from the high range to the low range, a so-called glossy tone is obtained in the high range, and a large volume is obtained in the low range. The performance as a musical instrument can be improved. In addition, it is possible to change the timbre by selecting the metal material.
