French clarinetist and composer, Hyacinthe Klosé (1808-1880) is predominantly known for his design improvements to woodwind instruments. However, his passion for the musical family is also apparent in his aids to the learning of the instruments, as in this book, 25 Études de Mécanism for Saxophones.

This Klosé study book covers technical aspects of the Saxophone, including articulation, breath control, rhythm, range and dynamics, among other elements. Compiled by a musician who had a clear enthusiasm for woodwind, 25 Études de Mécanism for Saxophones is clearly thought-out and assembled.
