ABSTRACT:
A head joint for a transverse flute comprises a hollow cylindrical wall 2 which terminates at its rearward end 4 adjacent an embouchure hole 3 extending through the cylindrical wall. The embouchure hole communicates with an acoustic chamber 5 defined within the cylndrical wall. A cap 12, fashioned with a rigid end wall 13 in the shape of a disc with the periphery of which is integral an axially extending annular flange 14, closes the rearward end of the cylindrical wall. The cap is fitted to the cylindrical wall with its annular flange making an airtight joint with the periphery of the cylindrical wall and with its rigid disc defining one end of the acoustic chamber. The cap may be a push fit over the cylindrical wall or be a push fit internally of the cylindrical wall. Alternatively, the cap could be screwthreaded to the outside or inside of the cylindrical wall. The axial position of the cap relative to the embouchure hole can, therefore, be adjusted, and the cap readily removed so that it and the interior of the head joint can be quickly cleaned. The cap may have an integral cylindrical extension directed from the periphery of its disc axially away from the annular flange to increase the length of the body of the head joint rearwardly of the embouchure hole. The cap improves the acoustic characteristics of the flute.
