Description

[Detailed description of the invention] The present invention relates to brass instruments such as horns.

A conventional Bb resin horn, for example, is known to have a structure as schematically shown in FIGS. 1 and 2.

That is, the mouthpiece 1 and the bell 2 are connected by the main pipe 3.

Three valves 4, 5, and 6 are interposed in series in this main pipe 3, and each of these valves 4, 5, and 6 includes a detour pipe 1 whose length is approximately one tone lower, and a detour pipe 1 whose length is approximately one semitone lower. Detour pipe 8,
Detour pipes 9 each having a length of approximately one and a half steps down are attached.

When all the keys corresponding to the valves 4, 5, and 6 are in the non-operating position, a conduit is established in which the mouthpiece 1 and the bell 2 communicate only through the main pipe 3, as shown in FIG. On the other hand, when the valve 4 is switched, for example, as shown in FIG. The length of the pipe is increased by an amount corresponding to the length of the detour pipe I, and the pitch of the performance sound is lowered by an amount corresponding to the length of the detour pipe I, that is, approximately one tone lower.

However, with conventional single horns like this, the treble range tends to be distorted and the treble range tends to be out of tune, which in turn narrows the range that can be played stably with good tone. The disadvantage was that it was not possible to provide a wide range of

In addition, some conventional Bb resin horns have one more valve interposed in the main pipe, and a detour pipe with a length that lowers the pitch by approximately % is attached to this valve. However, it had the same drawbacks as above.

In addition, there is a so-called double horn that eliminates the above drawbacks, but in such a double horn, for example, the rotary valve normally used as a valve has a double structure, etc. This has the disadvantage that the structure becomes complicated and the cost also increases significantly.

This invention has been made in view of the above circumstances, and it is possible to stabilize the sound in the high range, expand the range of sounds that can be played stably with good tone color, and furthermore provide a wider range of performance. The purpose of this invention is to provide a brass instrument which has a simple structure and can be obtained at low cost. One valve and five valves each having a detour pipe of a predetermined length are interposed in series in the first main pipe, and the first valve usually has a second main pipe connected in series with the first main pipe. B
A pipe line with a length corresponding to the B pipe, and the second main pipe is switched so that it is not inserted into the first main pipe, so that the entire pipe becomes a pipe line with a length corresponding to the HighF pipe. This is what I did.

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

In the figure, 11 is the mouthpiece, 12 is the bell, and these are the first
are connected by a main pipe 13.

This first main pipe 13 has six valves 14, 15, 16.
, 17, 18, and 19 are interposed in series, and the valve 19 has a second main pipe 2 of a predetermined length as described later.
5 is attached.

In addition, these valves 14, 15° 16, 17, 1B have a detour with a length approximately one step lower than the conduit in which the second main pipe 25 is inserted in series into the first main pipe 13. A detour pipe 21 with a length of about a semitone down, a detour pipe 22 with a length of about one and a half steps down, a detour pipe 23 with a length of about % step down, and a detour pipe 24 with a length of about % step down are attached, respectively. ing.

Note that when all the keys corresponding to valves 14 to 19 are in the non-operating position, as shown in FIG.
A pipe line is set in which only the second main pipe 25 corresponding to the Bb pipe is inserted in series with the first main pipe 13, and the length of this pipe line is configured to be equivalent to the length of the Bb pipe. has been done.

Furthermore, when the valve 19 is switched, as shown in FIG. 4, a pipe line is set up using only the first main pipe 13, and the length of this pipe line is set to correspond to the length of the HighF pipe. It is configured.

Therefore, in the state shown in FIG. 3, for example, the valve 1
4 and inserts the detour pipe 20 corresponding to this valve 14 in series into the first main pipe 13, the length of the pipe becomes longer by an amount corresponding to the length of the inserted detour pipe 20. The pitch of the played sound is lowered by an amount corresponding to the length of the detour pipe 20, that is, approximately one tone lower.

In addition, when the valves 15, 16, 17 and 18 are respectively switched, the pitch of the performance sound changes to the detour pipe 21, 22, in the same manner as above.
, 23, and 24, that is, approximately a half step, approximately one and a half steps, approximately % step, and approximately % step lower.

Therefore, by performing such valve operations, it is possible to obtain substantially the same performance effect as that of the conventional Bb resinle horn.

Next, when the valve 19 is switched as shown in FIG. 4, the second main pipe 25 corresponding to this valve 19 will not be inserted into the first main pipe 13, and as a result, it will correspond to the HighF pipe as a whole. The length of the conduit is set.

Therefore, while maintaining this state, for example, valve 1
4 and insert the detour pipe 20 corresponding to this valve 14 in series into the main pipe 13, this detour pipe ? The length of the pipe becomes longer by the length corresponding to the length of 0, and the pitch of the performance sound becomes longer by the length corresponding to the length of the detour pipe 20, that is, about 4
/3 notes lower.

Further, while switching the valve 19, the valves 15 and 1 are
6, 17, and 18 respectively, the same as above,
The pitch of the performance sound corresponds to the length of the detour pipes 2L22, 23, 24, respectively, that is, approximately % pitch, approximately 2 pitches, approximately 1 pitch,
It becomes lower by about a semitone.

Therefore, by performing such valve operations, it is possible to obtain substantially the same performance effect as that of a conventional High F single horn.

As explained in detail above, according to the brass instrument according to the present invention, a first valve having a second main pipe of a predetermined length is connected in series to the first main pipe that connects the mouthpiece and the bell. At the same time, second to sixth valves each having a detour pipe of a predetermined length are interposed in series with the first main pipe, and the first valve is normally connected to the second main pipe when the second main pipe is connected to the second main pipe. When the second main pipe is inserted in series into the first main pipe, the entire pipe becomes a conduit with a length corresponding to the Bb pipe, and the second main pipe is not inserted into the first main pipe. Since the entire tube is configured to have a length corresponding to a High F tube, it is possible to perform almost the same as a conventional Bb resin horn, and it can also be played almost the same as a conventional High F single horn. Therefore, it is possible to stably play high-pitched sounds, which in turn expands the range of sounds that can be played stably with good tone, giving a wider range of performance. The structure is simple, and this type of brass instrument can be obtained at low cost.
