Tom Jobim e Claus Ogerman: uma ontologia do arranjo musical.

This article discusses the partnership between Tom Jobim and Claus Ogerman, in the period between 1963 and 1980, contextualized in three lines of work identified in the career of the Brazilian composer. It discusses the concept of arrangement based on the "ontology of the musical work", as proposed by Treitler (1993), and offers an analysis of the songs "Wave" and "If everyone were like you", based on the original manuscripts of the composer and the arranger as well as sound recordings of the time, demonstrating the different ways in which the arranger can shape a work, from the literal transcription of the composer's idea until the complete reelaboration of a musical work in its formal, melodic and harmonic aspects. The arrangement constitutes a process that circumscribes a musical idea, even though circumstantially, in a sound utterance. and thus integrates the musical work as a whole in a process that, at the same time, reveals and transfigures the work's identity.
