LEDUC - M.Moyse Mecanisme-chromatisme Pour Flute Written by the French flautist and composer Marcel Moyse and published in 1927, Mécanisme-Chromatisme proposes a method to work on technique and chromaticism. Created for the use of advanced flautists, the exercises should help players to gain clarity and sonority. Considered as a maestro by some musicians, Marcel Moyse has composed many Flute methods and exercise books also published by Alphonse Leduc, such as 'Scales and Arpeggios' (1933), 'Daily Exercises' (1922) and 'On sonority' (1934). His methods are widely used and recognised worldwide.
