Clarinet with different diameters of the longitudinal bore

The invention relates to a clarinet with different Diameters of the longitudinal bore.

When using the drilling principle described in DT-OS 23 33 540 a number of important duodecimals can be improved significantly. The attempt to tune all the duodecimals optimally fails because notes in the high registers become considerably too low. This evil cannot be caused by any drilling that is based on this principle, can be satisfactorily remedied. By far the best solution to the intonation problem could be achieved with models in which the duodecimal sleeve is extremely narrowed, e.g. to 2.3 to 2.5 mra, and higher was set. This measure made expensive additional mechanics necessary for the pitch b '. The duodecimals and the tones of the high ones Position are correct in connection with an extremely wide-bored mouthpiece with a diameter of 15 mm in a cylindrical design and a Vessels 15.0 mm to 15.2 mm in diameter are relatively good. Because of the relatively abrupt paragraphs provided, i.e. because of the sudden cylindrical widening and narrowing in some places

The longitudinal bore results in a sound that is not particularly well-balanced is, with the long notes in particular not sounding free.

The object of the invention is to provide a clarinet, in particular a B » Clarinet, System Böhm, or an A, D and Ea clarinet too create, in which not only the duodecimals and dia tones of the high registers are correct, but also in which a well balanced voluminous » Sound is achieved in all registers. Ultimately, the aim is to achieve that the costly b 'additional mechanics can be dispensed with.

According to the invention, this problem can be solved in several ways Species can be achieved.

A first possible solution, especially for Bb clarinets, system Böhm, is characterized in that when the clarinet is divided into sections of equal length, each with a length of one cm, the diameter the longitudinal bore from the lower end of the upper piece, the 22nd section to the area between the! 5th and 10th section if the Division from the end of the upper part assigned to the vessel begins with, is constant or starting from the 22nd section into the area between the 15th and the 10th section slightly in size

upper end of the upper piece, the section 0, between "TTTTj and ■ ■ ~ mm is, and that the expansion is carried out so that the diameter of the longitudinal bore, starting from that between the 15th and the 10th section lying starting point of the expansion first increases more and more and less strongly towards the top to section 0.

Due to the design, there is a length hole in the Clarinet, which in the area of the enlargement In the cut considered a has an essentially elliptical limiting curve,

Since the expansion of the longitudinal bore creates space eoU, In order to influence certain tones, this gain in space, which increases in the range between the 15th and the 8th section on be greatest, even without forming the limiting curve of the expansion in the form of an elliptical curve can be achieved by the fact that one has the elliptical or kettle-shaped expansion by a conical expansion, a stepped expansion with an or several etching or a combination of these two possibilities and the gain in space required to influence the duodecimals and the tones of the high registers by setting them lower Creates tone holes and enlargement of the tone holes.

The second possible solution according to the invention, especially in a Bb clarinet, Boehm system, is therefore characterized in that when the clarinet is divided into equally long sections, each with one cm in length is the mean value of the volume of the longitudinal bore including the volume of the tone holes in this area from the lower end of the Upper pieces, the 22nd section to the area between the 15th and the 8th section, if the division begins with 0 at the end of the upper piece assigned to the vessel, is constant or starting from the 22nd section to the area between the 15th and the 8th section slightly corresponding to an increase in diameter of

total TTJT mm increases that this section is followed by a widening starting from a point between the 15th and the 8th section upwards, the volume of which increases that of a diameter of the longitudinal bore up to the upper end of the upper section, section 0, between - ■ - and γτ-τ mm and that the expansion

Let us say that the mean value of the volume of the longitudinal bore must be “The volume of the tone holes in this area is limited by that 15, and the 8th section, the starting point of the widening first increases more and more slowly towards section 0.

In the following the expression "mean value of the volume of the longitudinal bore" explained, If one plots the value of the volume in each section of the longitudinal bore in the form of a curve, this curve becomes each time have a sudden increase in the area of a tone hole, which decreases again at the end of the tone hole. It turns out to be thus a curve with bumps in the area of the tone holes. One distributes these additional volumes, which are attributed to the tone holes are, on the volume of the longitudinal bore, a smooth curve is obtained which runs essentially parallel to that which illustrates the volume of the longitudinal bore without tone holes. Wearing for example, the volumes of adjacent sections of a longitudinal bore a straight line is obtained with a cylindrical bore without including the tone holes. If one now counts the volumes of the Adding tone holes, you get with a cylindrical longitudinal bore and with evenly distributed tone holes each with the same diameter another straight line that runs parallel to the first straight line. This further straight line gives the mean value of the volume distribution of the individual Sections of the longitudinal bore including the tone holes. The course of the curve, which indicates the volume distribution, can therefore not only by changing the diameter of the longitudinal bore, but also by changing the position and size of the tone holes to be changed.

From this second possible solution it can be seen that in the first Line does not depend on the shape of the hole, but on the volume in the area of a certain section of the clarinet, if

mixed tones should be changed. After the "wide ventilation possibility, the favorable result, which was achieved with the help of the keeeelartlgen or elliptical shape of the longitudinal bore viewed in the longitudinal section, can also be achieved by providing either a conical longitudinal bore or a series of cylindrical sections of different widths and Then the tone holes are determined in terms of their size and position so that the same volume is available in the area of certain tones to be changed as according to the solution option given first, in which the longitudinal bore in the area of the expansion shows an elliptical boundary when viewed in longitudinal section. It is therefore not primarily the shape of the longitudinal bore that is considered in the longitudinal section that is essential, but rather the volume that results from the longitudinal bore in connection with the clay holes.

In the case of clarinets that are shorter than the B-flat clarinets, especially in the case of E-flat clarinets, the basic principle of the teaching given above can also be used, but an adaptation to the significantly shorter length is necessary. The solution to the problem posed at the beginning with much shorter clarinets than Bb clarinets, especially Eb clarinets, is characterized in that when the clarinet is divided into individual one cm long sections starting from the upper end of the mouthpiece channel as the section 0, the The diameter of the longitudinal bore of the upper part is constant starting from the lower end facing the lower part up to the area between the 15th and the 10th section, or starting from the lower end of the upper part up to the area between the 15th and the 10th section increases slightly in the order of magnitude of a total of r ~ r mm that this section is followed by a widening starting from a point between the 15th and the 10th section or between the tone hole of the tones f to a 'upwards, the diameter of which

7711853 12/15/77

Measure it increased to the upper end of the mouthpiece _{channel, the section O 1} between yrr to j- dd mm and that the expansion is carried out so that the diameter of the longitudinal bore starting from that between the 15th and the 10th section lying starting point of the expansion first stronger and upwards to the section 'increases less and less. The formation of the longitudinal bore, for example, in an Eb clarinet, i.e. a relatively short clarinet, is quite comparable to the formation of the longitudinal bore in a Bb clarinet if the longitudinal bore in the Eb clarinet or in a D'-clarinet up to and including the upper one is used Compare the end of the mouthpiece channel with the longitudinal bore of the Bb clarinet up to the upper end of the upper section, in each case calculated from the lower end of the upper section.

It is essential in all types of solution that an increase in volume of that space 'that is made up of the longitudinal bore and the clay holes composed, between the 15th and the 8th section of the upper section in Bb clarinets or between the 15th and 10th section of the clarinet in Eb clarinets and that the increase in volume in the lower area has a greater gradient than in the upper area.

A further development of the invention consists in the fact that when it is higher up Starting point of the expansion, the increase in diameter or volume enlargement is greater in the lower area than in the lower area lying starting point and the limiting curve of the longitudinal bore in the upper area is steeper or the increase in the mean value of the The volume of the longitudinal bore is less than at a lower beginning spu nid.

A particularly advantageous development of the invention is included therein see that between the 22nd section and a point between

7711853 15 / 12.77

your 15 * and the 8 = section or the 10, section for Eβ clarinets evenly narrow area represents the narrowest area of the clarinet.

Particularly good results that are beneficial to the intonation and affect the sound of the clarinet, according to the invention achieved that the vessel has the same diameter as the section 0 of the upper piece and a length that is about 2 to 8 mm shorter than this for tuning the notes b ', a', a ', g', f sharp 'and f to one of the basic pitches from a / 880 to a / 890 oscillations would be necessary and is dimensioned in its length so that in the area of the constant narrowest cross-section from the 22nd section to to a point between 1.5. and the 8th section are approximately in tune and that the tone holes of the tones b ', a', ace ', g', f sharp ', f sharp 'trills, £' and possibly also e ', which are in the area between the 8th and 16th section are lowered by 2 to 8 mm, in such a way that at a higher starting point for the between In the 15th and 8th section the widening of the longitudinal bore begins, the tone holes are offset further down and vice versa.

Due to the great expansion that occurs at a point between the 15, and Beginning in the 8th section, the clarinet becomes higher overall, which means that a longer keg would actually have to be used for the special affected tones V, a ', a flat', g ', f sharp', f sharp 'trill and f single part close. However, this would have larger tone holes in the area between the 15th section of the upper section and the 33rd section in the lower section, if to continue counting from section 0 of the upper section, require. To avoid this measure, the keg is shortened so that it is in the area between the 15th and the 22nd section the tones for medium diameters the tone holes are correct. The inconsistency in the area of the expansion, i.e. between section 13 and section 0, is highlighted lowering the duodecimal sleeve and the other notes mentioned above, namely a ', a flat', g ', f sharp', f sharp 'trill, f and possibly e', more balanced, The lowering of the tone hole e 'takes place less because of the

7711853 15.1177

Space enlargement, which results from this lowering combined with an enlargement of the tone hole, but about the correct one Distance to the deeper set decimal sleeve, which the Duodecime h "of the tone e 'influenced, as well as because of the sound.

Another measure according to the invention, which relates to correct tuning of the duodecimals and the tones of the high register, and which has a beneficial effect on the sound, consists in the fact that with increasing displacement of the tone holes of the tones b ', a', as' g ', f sharp', f sharp 'trills, £' and e 'the size of the tone holes increases and vice versa.

If you have a clarinet following the measures given above if you expand the volume in the area starting from a starting point between the 15th and the 8th section, where the enlargement first increases more and then increases less and less, and if one considers the area below between the 22nd section and the starting point of the expansion as the narrowest cross-section leaves the clarinet and provides the clarinet's keg with such a length that the tones in the narrowest range are to some extent and then the tones a ', a flat', g ', f sharp', f sharp 'trill, f and e' to tune the duodecimals and the tones of the high register offset downwards, it is recommended in a further embodiment of the invention to adjust the duodecimal sleeve according to the offset of the tone holes for the notes a ', a flat', g ', f sharp', f sharp 'trills, f' and e 'downwards to move, the amount of displacement with increasing expansion of the mouthpiece with the same diameter of the duodecimal sleeve decreases.

The shorter the keg is chosen, or the larger the widening of the

! The upper piece is, the lower the above-mentioned notes are b ',

; a ', as', g', f sharp ', f sharp' trills, f 'and e', this change remains

7711853 12/15/77

but not without influence on certain tones in the lower section of the clarinet, and the tones become proportionate up to about the 36th section too high. Of course, the same division into sections is chosen for the lower piece, i.e. the lower piece ends with the section " 23 to section 22 of the upper piece, each section corresponding to the distance of one cm.

In order to compensate for the length ratio of the tones in the lower section to the reduced tones in the upper section, namely the tones a ', a flat', g ', f sharp', f sharp 'trill, f', that is, to restore the above-mentioned reaction on the To compensate for tones in the lower piece, it is recommended in a further embodiment of the invention, the tone holes in the lower piece starting from the section adjoining the 22nd section of the upper piece to the 36th section or up to and including the tone hole for the tone g, with the exception of the Tone holes for the tone c ', the distance to the tone hole of the tone f is about 92 mm, approximately by the amount of the shortening of the keg or by the amount of the lowering of the tone holes of the tones b', a ', a flat', f sharp ', f sharp 'trill, f and e' _{(to be} lowered.

Another way of solving the problem presented at the beginning consists in the fact that the vessel has the same diameter as the section 0 of the upper part and optionally to the mouthpiece is somewhat widened and has a length that is about 2 to 8 mm longer than this for a re-tuning of the notes to one of the basic moods from a / 880 to a / 890 oscillations it would be necessary that the tone holes of the tones b ', a', as ', g', f sharp ', f sharp' trills, f and possibly e 'stay in the places to which they are assigned for a barrel matched to the corresponding basic mood, but that the Diameter of the tone holes for the notes a ', a flat', g ', f sharp', f sharp 'trill, f 'and possibly e' are enlarged so that the corresponding

Tones are correct again with the extended times and that all tone holes from the 15th section to the lower end of the clarinet are offset upwards in accordance with the regular lengthening, with the diameters of the tone holes maintaining their values, which are based on the corresponding basic tuning coordinated, unextended barrels are set. This measure is also based on the basic principle of the invention, which is to create a considerable gain in space in the area above a point between the 15th and the 8th section upwards, this gain in space increasing more in the lower area of this expansion and upwards becomes less and less. This gain in space is intended to lead to the narrowest hole, which is in the area between your 22nd section and a point between the and Section 8 is to be relatively large and based themselves from a clarinet with average Tonlochdurchmessern about an increase in diameter of the longitudinal bore of J ^ to -j QoE ^{mm Betl>.}

All the measures described above are mutually exclusive complement, have a beneficial effect on the mood, the sound and the volume of the tone of the clarinet.

The sound volume and the homogeneity of the sound in all registers can can be improved in a further embodiment of the invention in that the longitudinal bore is free of abrupt shoulders and changes in diameter is. The proposed diameter changes should therefore, if possible, not by means of cylindrical shoulders, but by means of smooth transitions can be achieved.

If a mouthpiece with a conical bore is used, the barrel can be widened somewhat towards the mouthpiece, specifically in relation to aaf> 'ne clarinet with a cylindrical mouthpiece.

It is essential that when using a mouthpiece with a conical bore, the diameter of the duodenal sleeve is lower than that of a clarinet with a cylindrical, that is, a further mouthpiece, and is provided with a larger diameter.

Further advantages, features and details of the invention emerge from the following description in conjunction with the claims and the drawing in which the invention is illustrated by way of example. In the drawing show:

In Fig. 1, the right limiting lines of the longitudinal bores are in each case represented by four upper pieces four different Bb clarinets, whereby the known bores are denoted by A, B and C, while the bore of the embodiment according to the invention is denoted by D. The

Upper part or the entire clarinet let for a better understanding divided into individual sections, each one cm long, so the upper pieces start with section 0 and extend to Section 22.

The known bore A has at section 0, d, h. at her upper The end to which the vial is attached has a width of 14.95 mm. From this width the bore narrows evenly conically to Section 12 "5 to a value of 14, 60 mm. From section 12.5 on the bore is cylindrical up to paragraph 18. A shoulder is provided here and the hole is at a value of 14.48 mm rejuvenates. The bore is again from section 18 to section 22 cylindrical.

The bore B in section 0 also has the width of 14.95 mm on. The bore is tapered conically up to section 2, 5, the bore tapering to a width of 14.80 mm. This closes a cylindrical section extends from section 2, 5 to section 7, 5. In section 7, 5 the hole is now of value 14.80 mm tapered to a width of 14.60 mm with a shoulder. From section 7, 5 onwards, the bore is consistently cylindrical up to End of the upper part.

The third known bore C has a width of at section 0 15.10 mm and tapers evenly conically up to the section to a value of approx. 14, 60 mm. From this section 5 on, the bore is uniformly cylindrical up to the end of the upper piece.

The bore D according to the present invention is designed to be uniformly cylindrical in the region from section 22 to section 13 and has a diameter of 14.60 mm. This is followed by an essentially elliptical or bowl-shaped delimitation of the

-13-

7711853 12/15/77

Hole in the lower area, i.e., at the front 13, to about the 7th cut a relatively large increase in diameter based on each length segment, while this increase in diameter upwards towards section 0 becomes smaller and smaller. In the section, the hole D has a diameter of 14.95 mm.

In the attached table I are the distances of the tone holes from the Upper edge of the upper pieces both for the clarinet according to the invention, the bore of which is denoted by D in FIG. 1, as well as for the known clarinet whose bore is denoted by B in FIG. 1.

The distances between the tone holes in the lower piece, i.e. in the 24. to 36. Abechnitt, are about 1 to 4 mm deeper than the known clarinet, but this depends on the length of the keg. Both clarinets have medium-sized tone holes. The distances to the upper edge of the upper piece are measured in each case to the middle of the tone hole. One Exceptions are the tone holes of the notes F sharp and F, which are in the inventive Clarinet are 3 or 10 mm higher than the corresponding tone holes F sharp or F in the known clarinet.

Fig. 2 shows the bore profile of the longitudinal bore of two Bb clarinets according to the invention. Curve E shows a longitudinal bore in which the tone holes of the tones b ', a', as ', g', f sharp ', f sharp ¹ trills, f and e' have the same distance from the upper edge of the upper piece as in the known one Clarinet B in Fig. 1 is the case. The tone holes of the notes mentioned are not offset downwards compared to the known clarinet, which is a certain standard dimension. In the case of the second clarinet, whose limiting curve for the longitudinal bore is designated by F, the pitches of the notes b ', a', ace ', g', f sharp ', f sharp' trill, f 'and e' are opposite the tone holes of the clarinet with the Hole E offset by about 5 to 9 mm downwards, whereby the offset is not the same for all tone holes. The clarinet with

7711853 12/15/77

-Xt-

the hole F has a shorter one because of the lower tone holes Barrel as the clarinet with the E hole.

As can be seen from the comparison of these two curves, the course of the holes, the starting point of the widening in hole E is one section or one cm deeper than in the case of the Hole F. The increase in diameter in the individual sections is much greater in the lower area of hole E than in the bore F. This direct comparison gives the impression that the clarinet with the bore E has a larger volume for the development of the vibrations of the individual tones would have than the clarinet with the bore F. In fact, however, through that Relocate the tone holes of the notes b ', a', a flat ', g', f sharp ', f sharp' trills, f 'and e' an additional gain of space in this area has been created by the deeper lying tone holes, which are due to the offset are enlarged in their diameters downwards. Because of this measure is despite the smaller expansion in the area created between the 8th and 14th section essentially the same volume, if not only the volume of the longitudinal bore, but also the volume of the tone holes added, so that similar results despite the different design of the Longitudinal drilling can be achieved. For an exact comparison of the two holes diameter values are given in mm on the abscissa. The hole F could also be replaced by a conical hole with a corresponding correction in the height of the Tonlücher or it it would also be possible to start the expansion further up, for example in the 8th or 5th section, and then place one accordingly large paragraph to be provided. The loss of space that occurs here would then have to be due to the tone holes being set even deeper larger diameter can be compensated for again to some extent.

7711853 12/15/77

In Fig. 3 the course of the bore of an Eb clarinet is shown. In this clarinet, too, the starting point of the expansion is provided approximately in the same area as in the Bb clarinets according to FIG. 2 and the bore below this point at which the expansion begins is also cylindrical as in the Bb clarinets in FIG. 2 to the end of the upper section, which for the Bb clarinets up to section 22, but for the Eb clarinet only up to section 20, 5. With regard to the increase in diameter per section, the course of the expansion corresponds approximately to the course of the longitudinal bore F in the Bb clarinet according to FIG . The Eb clarinet according to FIG. 3, like the B flat clarinets according to FIG. 2, is divided into individual sections, each one cm in length. However, while with the B-flat clarinets the division begins at the upper edge of the upper piece, the E-flat clarinet begins with the division at the upper end of the mouthpiece channel, ie the expansion extends to the upper end of the mouthpiece channel. This change is necessary because of the shorter length of the Eb clarinet compared to the Bb clarinet. In Fig. 3, the tone holes of the notes a 'and f · are shown for comparison with the B flat clarinets. In addition, the length of the mouthpiece channel, the barrel and the upper part can also be seen. The upper end of the mouthpiece channel begins at section 0 and the mouthpiece channel extends to section 4.5. The keg extends to section 5.6. The top of the clarinet extends from section 5, 6 to section 20.5. At the points mentioned, ¹ short horizontal lines are drawn in the curve. The lower end of the Mundetückkanaleo iet with I, the lower end of the Fäßchena with II and the lower end of the upper part with III, in order to better emphasize the length of these parts.
