Example 2
The clarinet prepared by the embodiment of the invention is compared with the traditional clarinet in tone and weight:
Tone color (one)
In the implementation of the performance, the conventional wooden clarinet and ABS resin clarinet are identical to the epoxy clarinet prepared in this embodiment in terms of timbre, and can be played from e of the small word group to c 4 of the small word four group, but the timbre characteristics are somewhat different. When the clarinet of the three materials plays some classical music simultaneously, for example: when the clara concerto or the mozate A major concerto is in jumping arpeggies from e of the small word group to d 3 or e 3 of the small word group, the sound of the traditional wooden clarinet is more muddy compared with the tone of the ABS resin clarinet in terms of hearing effect of listeners, and the air flow vibrates the whistle piece to generate resonance with the traditional wooden tube body, so that the classical tone of the traditional clarinet with stronger penetrating power is reflected. Compared with the traditional wood clarinet, the ABS resin clarinet is lighter and thinner in tone, and the sound penetrating power is not as strong as that of the traditional musical instrument when the ABS resin clarinet is played. The epoxy resin clarinet prepared by the invention has the advantages that tone bass, low-sediment, high-sound and crisp tone emitted after resonance with the epoxy resin clarinet body in performance has the characteristic of low sediment of the traditional wooden clarinet, and the crisp sound of the ABS resin clarinet is fused, so that the sound production of a player and the study and use of a beginner are more convenient compared with the traditional clarinet.
(II) weight
The self weight of the musical instrument varies from visual perception when played by a player. Compared with the traditional clarinet, the epoxy resin clarinet prepared by the invention has lighter weight, and by experiments, taking the same tone A clarinet as an example, under the condition of installing the same flute head and key, the weight of the epoxy resin clarinet prepared by the invention is about 0.71kg, and the weight of the traditional clarinet on the market at present is about 0.88kg. Compared with the epoxy resin clarinet prepared by the invention has relatively light weight, and a beginner can better relieve the ache of the thumb of the right hand, improve the comfort and reduce the fatigue and damage of muscles and joints when playing for a long time.
The foregoing is merely a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above embodiments, but all technical solutions falling under the concept of the present invention fall within the scope of the present invention, and it should be noted that, for those skilled in the art, several modifications and adaptations without departing from the principles of the present invention should and are intended to be regarded as the scope of the present invention.
