Aurelio Magnani (1856-1921) was a teacher of and performer on the clarinet.
He taught in Venice and Rome and produced many pupils. He wrote a clarinet method in addition to the Mazurka Caprice that can be heard on some recent reissues on CD of historical recordings by Louis Cahuzac.
The work is pure charm throughout, and shows the craftsmanship of someone who knows the clarinet intimately. Source : Wikipedia
