The present invention relates to a mouthpiece of the type used in woodwind and brass-wind musical instruments and other components of those instruments.
The present invention concerns mouthpiece manufacture in root and branch of briar boiled and dried in different duration, and 6 months of curing, up to two years and more than two years, with a waxed finish, for the coupling thereof in any woodwind and brass-wind musical instrument, accordingly, in addition to other components of those instruments, manufactured in the same material.
The mouthpiece, fundamental component of the musical instruments treated herein, is used in the saxophone, clarinet, transverse flute, recorder, etc., for the production of sound by forced conduction of the air expelled by the player into the body of the instrument. Both in the woodwind and brass-wind instruments the practice is to use mouthpieces of ebonite in diverse shapes and sizes, in terms of the pitch and tone it is sought to obtain.
The only advantage that is obtained with the ebonite mouthpiece is the specialty of its sound, jazz, classic, etc., obtained with standard different measures of opening and depth of the mouthpiece.
In spite of that advantage, ebonite mouthpieces have certain disadvantages. For example; they can cause allergy problems; their changeability for excessive cold or heat, which produces mistuning of the instrument; excessive taste and smell of a synthetic product; excessive diversity in opening and depth measurements of the mouthpieces for the production of different pitches, which entails a certain difficulty for a proper selection and excessive effort from the players for producing the sound, more so for beginners. With reference to the sound, this does not manage to be as enveloping and balanced as could be desired, producing very irregular waves in the same note, of different length and depth, at the same time as undesirable harmonics.
The mouthpiece herein disclosed is manufactured in a single size for each type of instrument, in briar wood, either root, or branch thereof, moistened from the extraction or cutting thereof until its boiling in water, for 16 hours; drying under anaerobic conditions for a minimum period of 6 months and cured under cover, in normal environmental conditions, for 6 months, up to two years and more than two years, with a final wax-based finish. It goes without saying that the longer the curing time, the better the sound quality.
The invention provides a mouthpiece and other components of the aforementioned instruments that are unalterable, unaffected by humidity and do not suffer from expansion or contraction. It also provides a natural hard high-density product, and therefore a better producer and conductor of sound and at the same time flexible, a most appreciated characteristic in the reeds which produces a natural and enveloping sound, and what is greatly appreciated by the musicians, that a given mouthpiece, or reed, in the event, with minimum effort, facilitates a wide range of sounds, jazz, classic, soloist, orchestra and band.
To complete the description of the invention and the scope thereof, the descriptive specification is accompanied with a set of drawings and the graphical transcript of the natural musical notes, DOH, RAY, ME, FAH, SOH, LAH, TE, obtained from the same tenor saxophone, using an ebonite mouthpiece and a briar mouthpiece for the comparison thereof.
FIG. 1.—(page 1). Shows an inverted profile of the tenor saxophone mouthpiece.
FIG. 2.—(page 2). Shows the plan view of the same mouthpiece.
The length of this mouthpiece is between 6 and 10 mm more than the length of the range of tenor saxophone mouthpieces. And the thickness is between 0.1 and 0.2 mm more than the thickness of those mentioned.
As for the comparative study, it can be observed in the transcript of the note DOH, page 2, the waves in this note, produced with an ebonite mouthpiece offer a clearly toothed appearance, with more marked differences in the amplitude of the waves. However, with the briar mouthpiece, although offering the same succession of waves of different amplitude, in no way is the appearance sawtoothed and the difference in the amplitude of the wave pairs is less perceptible.
In the comparison of the note RAY, page 3, although no notable differences are perceived between the notes produced by the different mouthpieces, it can be appreciated that the regularity of the amplitude of the wave pairs is more accused with the briar mouthpiece.
In the transcript of the note ME, page 4, although the wave is less toothed with the ebonite mouthpiece than the note DOH, with the briar mouthpiece it attains a purity and regularity in sound, comparable with that of the tuning fork.
As it can be observed in the transcript of the note FAH, page 5, although the ebonite mouthpiece improves with regard to the other notes, with the briar mouthpiece perfection is almost reached in the proportionality between the wave length and amplitude.
From the mere observation of the note SOH, page 6, the difference in sound is clearly deduced, much more regular with the briar mouthpiece, without that toothed aspect of the wave corresponding to the ebonite mouthpiece.
And this is how the note LAH, page 7, is observed for the ebonite mouthpiece, in the upper part of the wave it is shown toothed, which does not occur with the briar mouthpiece which surpasses the former in regularity.
And to conclude with the note TE, page 8, here the differences in wave morphology are less perceptible, although the difference in wave amplitude gives an idea of a substantial difference as regards the sound range amplitude.
