Our recent analyses of Aphex Twin and Autechre works, which are typical of the semi-experimental electronic music current called Intelligent Dance Music (IDM), have revealed, through structural analysis, the presence of shared features in the organization of microrhythmic sets (MRS). MRS frequencies are mostly situated between the highest rhythm periodicities (10 to 20 e/s) and the human hearing threshold (20 to 50 e/s). Characterized by their high frequencies, the “textural sets” are devoid of dynamism when short and include timbre variations when they are long. This type of set generally results in a texture contrasting with the rhythmic content. Low frequency MRS form the “gestural sets.” They are usually long and prone to groupings as well as dynamic variations. The effect caused by this type of MRS is the one that suggests rhythmic continuation or gesture.
