Description

112

The invention relates to the production of woodwind musical instruments, in particular a bassoon.

The known design of the small knee of the bassoon, containing sound holes and valves connected to the keys by means of levers and rollers 1.

A disadvantage of the known small tribe of the bassoon is the inconvenience when playing the phgoth.

The aim of the invention is to increase the comfort when playing the bassoon.

The goal was achieved by the fact that the small knee of the bassoon, which contains sound holes and valves connected to the keys by means of levers and rollers, has an additional lever on the left side of the C key valve located below the key of the C octave valve with contact and in contact with the side the key of the octave valve L, the lower end of the double-sided lever of the octave valve To is placed under the key of the octave valve L with a gap, and the keys of the octave valve L are installed along the length of the small knee above the key octave Prior to valve.

FIG. 1 shows the small knee of the bassoon on the left side; 2 shows the connection of the C-sharp key of the valve to the key of the octave valve L.

The small knee of the bassoon contains sound holes 1 and valves 2 connected to key 3 by means of levers 4 and rollers 5, On the left side of key 6 of the valve To 7, an additional lever 8 is installed, located under the key 9 of the octave valve Up to 10 with a clearance ( on the order of 5 mm) and a key 11 octave of the valve L 12 in contact with the left side, the lower end of the double-sided lever of the 13 octave valve Up to 10 is placed under the key of the 11 octave valve L 12 with a clearance (about 5 mm), and -. L-12 is installed along the length of the knee above the button 9 of the octave valve Up to 10. The lower end of port 14 is double-sided on the lever of the octave valve L 12 shortened, and the lower end of the double-sided lever of the 13 octave valve Up to 10 is extended. Additional lever 8 has a bevel shape (not shown).

The lever 15 of the roller 16 is set below its former position approximately 14 mm opposite the key 9 and the slider on it.

5 Functions of the small knee when playing the bassoon in the following way.

The performer presses the keys of his left thumb simultaneously

9k 6 octave valves Up to 10 and 10 C-sharp 7. The keys 9 and 6 are lowered, at the same time the octave valves Up to 10 and C-7 sharp up, opened aperture. With the release of the p-alphabet with key 9 and 6, the actions of these

15 key and valves occur in the opposite direction.

The actuator presses the keys of the 9 octave valve Up to 10, which is lowering with ь together with the lower lever 135J

20 raises the octave valve Up to 10, opening the hole. Then the performer moves the thumb to the keys 11 of the octave valve L 12, releasing the keyboard 9. The key 9 rises, the octave valve Up to 10, lowering, closes the sound hole. Keys 11, lowering along with the lower lever 14, raises the octave valve L 12.

30 Simultaneously 11 Octave Keys

The valve L 12, with its left side, presses on the figurative bevel of the additional lever 8. The latter lowers together with the button 6 of the valve C-sharp 7.

JJ Valve To-sharp 7, lift up, away from. kryvaet sound hole. When navigating again to the keys 9, the actions of the 7-iaroB and rollers occur in the opposite direction.

. Singer thumb

Left hand presses the 9 keys of the octave valve To 10. Keys 9, lowering, raise the octave valve To 10, opening the hole. Then the performer with the slidable movement of the thumbless finger passes, the minutes of the keys of the 11 octave valve L 12, to the keys 6 of the C-sharp valve 7. At the same time, the released keys 9

50 rises, octave valve Up

10 is released by closing the forging hole. Keys 6, down together

with the additional lever 8 and not acting on the keys 11, raises the key to 55 ° C, 7 When moving more than a finger, Djoro finger again on the keys 9, the min of the keys of the 11th octave valve L 12, acting as levers and rollers

 in the opposite direction. When the keys 11 are actuated, two octave valves L 12 and C-7 are simultaneously actuated, and when the keys 6 are actuated, only the valve Dise 7 is actuated. A guaranteed gap of about 5 mm between the key 11 and the lower lever 13 and between the key 9 and the additional lever 8, it ensures that the key does not touch when operating with the keys 11 and 9 with the levers 13 and 18, respectively.

The ability to simultaneously use octave valves Up to 10 and C-7 allows you to use auxiliary fingering earlier. the unworkable trill of the first octave. The indicated use of valves makes it possible to perform at a higher quality level with a simple fingering-rehearsal movement the C trill of a small octave C-sharp the first octave and the tremolo L is the small octave of the C-low C sharp the first octave; L small octave - C sharp first octave.

The invention ensures the synchronous movement of the octave valves L and C-sharp and provides a relatively clearer legato stroke from the sounds of L or C-bolus of the first octave to sounds, such as C-small octave or first

octaves, or Before the first or second octaves.

Neighboring key location octave valves To and C sharp

5 is rational. It creates the convenience and simplicity of the fingering transitions in the most common italic movements of the thumb of the left hand and does not give negative results.

The invention increases convenience when playing the bassoon.
