Abstract
We introduce a web-based database that gives details of the acoustics of soprano and tenor saxophones for all standard fingerings and some others. It has impedance spectra measured at the mouthpiece and sound files for each standard fingering. We use these experimental impedance spectra to explain some features of saxophone acoustics, including the linear effects of the bell, mouthpiece, reed, register keys and tone holes. We also contrast measurements of flute, clarinet and saxophone, to give practical examples of the different behaviour of waveguides with open-open cylindrical, closed-open cylindrical and closed-open conical geometries respectively.
