A piccolo comprising a conical-bore headjoint, and a cylindrical-bore main body having toneholes of particular size disposed at particular intervals along the length of the body. The training device includes a strap adapted to be fitted around the top of a paddle of the goalie’s hockey stick, and a finger channel vertically affixed to the strap and positioned for removable holding his index finger so that the index finger is substantially pointed down the paddle of the goalie hockey stick when he is holding the goalie hockey stick. At high temperatures, the frequency change versus concentration curve mirrors the Henry’s gas law, such that the concentration of a gas sample in liquid solvent is proportional to the concentration or partial pressure of the sample in gas phase.
