Idiomatic Improvisation over anamorphic harmony

rhythm as catalyst of melody and harmony

Abstract

In this article, we have reported idiomatic improvisation procedures with timeline applications taken from the Rhythmic Series by José Eduardo Gramani and rhythmic phase-shifting processes developed by Steve Reich, Michael Udow and Cesar Traldi by means of live looping techniques. The idiomatic improvisation, in this context, was subordinated to the harmonic changes engendered by the rhythmic aspect. Laboratories were conducted with a live looping workflow in the DAW Reaper to manage the sound material, submitting timelines taken from the Series to phase-shifting by rhythmic additive process, to lay a comping base. The creation and performance of an audiovisual artistic product and its analysis, and the tangency with the anamorphic visual art of Patrik Proško were generated, which are the result of a master's paper in which methodology specific to the field of research in arts was adopted. Visual tools were used for the analysis of the piece generated in laboratory, such as Sonic Visualiser. Finally, it was considered that rhythm became a catalytic element of harmony and improvisation, in turn generating harmonic anamorphism. The innovative factor in this work lies in the combination of rhythmic concepts and live looping techniques, engendering a new artistic construct.
