A wind instrument is constituted of a mouthpiece and a pipe structure including tapered/straight pipes. The pipe structure is constituted of a blow member and a branch pipe. The branch pipe is branched into a main pipe and an auxiliary pipe, which are straight pipes having openings and connected together in a branch shape. The blow member is connected to a branch point of the branch pipe. The branch pipe simulates resonance characteristic of a tapered pipe having a predetermined length, a predetermined distance between the upper base and the vertex, and a predetermined sectional area of the upper base commensurate with the sectional area of the main pipe. |
