The Mouthpiece – link between the wind player and the instrument
Due to its function the mouthpiece is very important, as it needs to suite for the wind player and must help him fulfil his personal ideas and desires in regard to lip, timbre, sound quality, competence and stamina.
The mouthpieces of the comprehensive JK programme help the wind player to achieve the best sound and to meet his individual demands in an easier way. The characteristic sections of a mouthpiece form a functional unit.
Even slight changes on a mouthpiece section cause a changed behaviour of the mouthpiece. For the conscious selection of the right mouthpiece, the relationship between the shape and the function of the particular parts must be understood.
The material selection – decisive for excellent sound and response quality
During the development of the JK mouthpieces, we paid special attention not only to the functional interplay of the particular sections of the mouthpiece but also to the material selection. Only this way, we could achieve the excellent sound and response quality. Thanks to the use of a mouthpiece that is coated with precious metals (silver plated, gold plated), a change of the surface due to sweat or saliva can be avoided.
A mouthpiece with plastic rim is advantageous especially outside and in the cold season, because it provides a good protection against cold. Furthermore, the typical sound quality is maintained.
Perspex mouthpieces, which also protect against cold, are used especially for teaching purposes because they are completely made of transparent acrylic glass. Their sound character is smoother than the one of metal mouthpieces.
determines how much lip surface can vibrate.
The cup diameter has to be selected big enough to guarantee the mobility of the lips.
This way, a perfect sound quality and a vibrating tone are archived. The appropriate cup diameter is determined by the physiologic properties of the individual wind player (jaw position, teeth position, constitution of the ring musculature).
differentiate timbre and sound quality.
A deep cup means a big sound volume, it creates a resonant and smooth sound. This sound quality is preferred in the concert sector.
The medium cup allows the most extensive sound variation. Stylistically, its bright, clear sound offers the most possibilities.
The flat cup creates a medium hard, brilliant sound, suitable particularly for the jazz and dance music sector. High pitches are achieved in an easier way.
The extremely flat cup with its hard, brilliant sound is suitable especially for wind players with very thin lips.
Difficulties in the high sound range can be reduced.
Thanks to its especially designed flow of lines, the cup run of the JK mouthpieces represents a linking unit between lips and bore.
Therefore, the JK mouthpieces distinguish themselves by an extraordinary clear and excellent sound quality.
A models: | deep cups |
B models: | medium deep cups |
C models: | medium shallow cups |
D models: | shallow cups |
E models: | very shallow cups |
W models: | with extra-broad rim |
Models without letter: | medium cups |
guarantees lip mobility and comfort suit.
Thin rims guarantee the most mobility and allow all tongue techniques. However, it is more exhausting to play on them because the pressure on the lip musculature emanates from a very narrow area and therefore, its impact is stronger.
A rim that is too wide often gives a comfortable feeling but it fixes the lips into a certain position and thus restricts their mobility.
The rim of the JK mouthpiece is shaped to create a contact that is as comfortable as possible. The shape of the lips determines the width of the rim and also the shape of the cup.
Therefore, wind players with thick lips tend to use a mouthpiece with a wider rim and a bigger cup. The inner and the outer rim build the contour whose highest point(with all JK mouthpices) is located in the first third of the inner rim area.
If the highest point is transferred to the outside and the radius of the inner rim is amplified, the rim of the mouthpiece seems to lay more comfortably on the lips.
However, the strong fit is affected and the brilliant sound gets lost, because the tones get faint.
determines how much sound volume is developed in the instrument.
The size of the bore determines how much sound volume is developed inside the instrument. The length of the inner bore (= cylindrical part of the bore) influences the resistance and attack decisively. If it is too short, this will affect the sound stability. If it is too long, this will affect especially the high register and the intonation.
The back bore is also a very important part of every mouthpiece. It is significant for the continuation of a concentrated air column inside the instrument.
For all JK-mouthpieces the following variants of the back bores are valid:
Back bore A1: | small, narrow back bore |
Back bore A2: | mean size back bore |
Back bore A3: | big, wide back bore |
The particular series-back bore is not specially indicated on the mouthpiece.
