小号,铜管乐器。其号嘴杯形;号管细而长,弯成长圆形的圈;末端呈喇叭形。因管上有3个阀键,单独或联合使用,可降低其原来音高1个至6个半音,故可以吹出它的音域中所包含的全部半音。小号是移调乐器,即谱音比实际发音高大二度,通用为降B调音域为好或更高(实际发音),有些爵士乐演奏者可以吹到更高。19世纪末期有F调小号和降E调小号,体积较大,音色宏亮,但演奏时不如降B调小号灵活,现已极少使用。还有一种低音小号(C调或降B调),音域比小号低八度,用于瓦格纳的《尼伯龙根的指环》中。此 Trumpet, brass instrument. Its mouth beak shape; number tube thin and long, curved into a circle round; end was horn. Because of the three valve keys on the tube, used alone or in combination, the original pitch of 1 to 6 semitones can be reduced so that all the semitones contained in its range can be blown out. The trumpet is a transposing instrument, that is, the spectral sound is two degrees taller than the actual sounding, the common is better or better than the B tuning range (actual sounding), and some jazz players can blow higher. The late 19th century F trumpets and trumpets E trumpet, larger, loud, but not as good as playing B trumpet trumpet flexible, is now rarely used. There is also a bass trumpet (C or B) with an octave lower than the trumpet for Wagner’s “ring of the Nibelungen”. this
