The pursuit of beautiful soundin our instrument passes, in addition to the taste of the performer and the fashions dictated by the great names of the moment, for the different ways of posing the moving parts that, between the instrument and the instrumentalist, play a decisive role in defining the timbre, i.e. the quality of the sounds produced. Moving parts during the act of blowing that we can classify in: internal position of the tongue in its variables, ways of posturing the lips, closed or open throat, variables in the positions of the jaw, use of the intercostal muscles in assisting the interventions of the diaphragm before and after the production of sound in relation to the abdominal muscles.
