摘要： A bore-variable leadpipe includes a mouthpiece receiver integrally formed on a tube body of a brass instrument and a mouthpiece adaptor detachably assembled to the mouthpiece receiver. The mouthpiece receiver internally defines a first bore, in which an assembling section, a tapered section and an air-guiding section are sequentially formed. The mouthpiece adaptor has a receiving end for receiving a mouthpiece therein and an assembling end for engaging with the assembling section, and internally defines a second bore between the two ends. When the mouthpiece adaptor is assembled to the mouthpiece receiver, the second and the first bore are aligned and communicable with each other to form a conical passage and a cylindrical passage. The leadpipe can be changed in its bore size by assembling a mouthpiece adaptor of a different bore size to the mouthpiece receiver, so that the same brass instrument can be used with differently sized mouthpieces.
