An improved French horn includes a coiled tubular body having a bell end, a curved inlet end and a plurality of valves formed thereon between the bell end and the inlet end for controlling a flow of air through the French horn. A mouthpipe has a mouthpiece end, a curved outlet end and a substantially straight section between the mouthpiece end and the outlet end. A pipe detachably interconnects the inlet end of the coiled tubular body and the outlet end of the mouthpipe. The pipe is configured so that the interconnected mouthpipe may be situated at either one of two positions relative to the body, including a first position in which the substantially straight section of the mouthpipe is substantially tangential to the coiled tubular body, and a second position in which the substantially straight section of the mouthpipe is away from the first position and close to the valves of the coiled tubular body.
