Overview: The reed is that thin blade that vibrates when a player blows into his instrument, and can produce very different sounds. This is precisely the secret of a large number of instruments: clarinets, saxophones, oboes, bassoons, contrabassoons. It is a slat that must be replaced periodically. It must be moistened and fixed very carefully in the mouth of the instrument. And then it can produce magical notes. In the studio the regular guests Giovanni Bietti and Adriano Mazzoletti for classical music and jazz, with them Piero Angela will show curious films, for example he will take viewers to the Camargue, where the reeds from which the most valuable reeds are obtained are grown. And then they will show recordings by great soloists such as Sidney Bechet, Benny Goodman and others. Piero Angela will duet on the piano with the flautist Andrea Griminelli and then with the saxophonist Francesco Cafiso.
