Etude du Rythme is an educational tool proposed by Georges Dandelot (1895-1975), a French composer, following the concept that rhythm is the foundation on which melody and harmony are then layered. It was conceived toprogressively teach musicians how to deal with complicated rhythms such as those used by Bartok or Ravel. This volume is the first of five composing a step-by-step method to learn and master rhythm in music. It covers basics andsimple melodies - the second volume introduces more complexity on the same concept, then the third one should help pianists to play different rhythms with each hand. Volumes four and five use complex combinations of rhythms andmelody with binary and tertiary tempos.
