Description
BRIEF DESCRIPTION OF THE DRAWINGS
(1)
DETAILED DESCRIPTION
(2) The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar elements. While embodiments may be described, modifications, adaptations, and other implementations are possible. For example, substitutions, additions, or modifications may be made to the elements illustrated in the drawings, and the methods described herein may be modified by substituting, reordering, or adding stages to the disclosed methods. Accordingly, the following detailed description does not limit the claimed subject matter. Instead, the proper scope of the claimed subject matter is defined by the appended claims.
(3) The invention relates to a B/F tenor trombone for children according to the independent claim. The invention pertains to the field of brass wind instruments, in which sound is produced by means of excitation of natural resonance of the instrument in response to lip vibrations created by the trombonist.
(4) It is an object of the invention to provide a tenor trombone which makes it possible to overcome the drawbacks of prior art, and to provide a trombone, in particular for children, which is easy to handle, and which does not require change of the playing technique when changing over to the B/F tenor trombone.
(5) This object is attained by a B/F tenor trombone for children according to the independent claim. Advantageous aspects constitute the subject-matter of the subclaims.
(6) The invention discloses a B/F tenor trombone for children, comprising a sound part (bell) and a slide, composed of an inner slide and an outer slide being movably disposed on the inner slide. The total length formed by sound part and slide has a tubing length L.sub.s1+L.sub.s2+L.sub.s3+L.sub.z1+L.sub.z2+L.sub.z3 (for tuning in the 2nd natural tone B). Section L.sub.s2 as described in the following comprises a circumferential tube bend. In the 1st register, the slide has a tubing length L.sub.z1+L.sub.z2+L.sub.z3 of less than 150 cm (in particular in the range of 130 cm to 140 cm, particularly preferably 1328 mm). The sound part has a length L.sub.s1+L.sub.s2+L.sub.s3 of more than 125 cm (in particular of 130 to 140 cm, particularly preferably 1380 mm). Thanks to the tubing length of the slide, the B/F tenor trombone is easy to handle. As a result of the B tuning and the extended tube part it is not necessary to change the playing technique when switching over to a conventional B/F tenor trombone. This B/F tenor trombone, compared to the standard B/F tenor trombone (slide length 1585 mm), has a shortened slide (slide length 1328 mm) and a F quart valve with full functional capability. The total tubing length corresponds to the standard B/F tenor trombone, wherein the sound part is accordingly constructed with a longer shape due to the shortened length of the slide.
(7) Particularly preferably, the slide has a length L.sub.z1+L.sub.z2+L.sub.z3 in the 1st register of less than 135 cm. The sound part has a length L.sub.s1+L.sub.s2+L.sub.s3 of more than 145 cm. The length L.sub.z1+L.sub.z2+L.sub.z3 of the slide of known B/F tenor trombones is 1585 cm, so that the required tubing length represents an effective shortening of the instrument (approx. 15 cm) and enables accordingly enhanced handling. Due to the extended sound part, balance of the instrument is improved.
(8) Particularly preferably, the sound part (in the tube run) has a completely circumferential tube bend. Said circumferential bend extends the tubing length of the sound part while maintaining the outer dimensions of the sound part. In the simplest case, the completely circumferential tube bend encloses an angle of 360.
(9) According to a preferred aspect, the completely circumferential tube bend includes two straight, parallel (to one another) extending sections and two tube bends (which are each interconnected at an end section to one of the straight sections). Hence, after one full turn, the length can be selected in accordance with the shortening of the slide.
(10) According to another advantageous aspect, the sound part comprises a quart valve. The quart valve can be adjusted between a first position and a second position using a valve lever. The quart valve is connected to the completely circumferential tube bend in the first position, and is additionally connected to a valve slide in the second position. The tonal effect created by the quart valve corresponds to that of a standard B/F trombone.
(11) According to a preferred example, the valve slide has a length of 95 cm. Said length of the valve slide produces the same tonal effect as that of the quart valve just like with a standard B/F trombone.
(12) According to another particularly preferred aspect of the invention, the instrument length (outer edgetube bendsound part to outer edgetube bendslide part) is in the range of 98 to 103 cm. The standard B/F trombone is approx. 15 cm longer, resulting in advantages concerning handling and balance, which lead to overall enhanced playability for children. Moreover, the pitch range is broader than that of the secundo trombone. Additional tones F/E/E-flat/D/C-sharp can be played in the low-pitch range.
(13) Hereinafter, the invention will be described in more detail with respect to the example illustrated in the attached drawing.
(14) The illustrated B/F tenor trombone has a sound part 2 of a first sound part tube section L.sub.s1, a second sound part tube section L.sub.s2 (comprising an extension section) and a third sound part tube section L.sub.s3. The illustrated B/F tenor trombone 1 has a slide 3 composed of an inner slide and an outer slide being movably disposed thereon, wherein in this illustration, only the outer slide can be seen, which is fully extended in accordance with the 1st register. The slide 3 comprises a first slide tube section L.sub.z1, a second slide tube section L.sub.z2 and a third slide tube section L.sub.z3. The entire tubing length, encompassing sound part 2 (comprising an extension section) and slide 3, results in a tubing length L.sub.s1+L.sub.s2+L.sub.s3+L.sub.z1+L.sub.z2+L.sub.z3 for tuning in the 2nd natural tone B, which means a length which is selected such that tuning is produced in accordance with a standard B/F tenor trombone.
(15) In the illustrated example, L.sub.s1 is (612 mm), L.sub.s2 is (579 mm), L.sub.s3 is (189 mm), L.sub.z1 is (580 mm), L.sub.z2 is (576 mm) and L.sub.z3 is (172 mm). The length of the tube bends L.sub.s3 (189 mm) and L.sub.z3 (172 mm) results from the distance of the imaginary end faces which adjoin the straight tube sections.
(16) The sound part 2 comprises a completely (360) circumferential tube bend 5 which has two straight (substantially) parallel sections 52 and two adjoining semicircular tube bends 51. The length of the completely circumferential tube bend 5 is formed by the length of the parallel sections 52 (approx. 5-10 cm) and the length of the two semicircular tube bends 51 (approx. 5-10 cm).
(17) The sound part 2 has a quart valve 6 which can be adjusted between a first position and a second position with the aid of a valve lever 61. The quart valve 1 is connected to the completely circumferential tube bend 5 in the first position. After changeover to the second position, it is additionally connected to a valve slide 4. The illustrated valve slide has a length of approx. 95 mm.
(18) The advantages of the invention in particular result from the (total) instrument length (outer edgetube bendsound part to outer edgetube bendslide part) of 101 cm.
