This lecture performance presentation will outline the music transcription and arrangement process by converting a music performance recording into a sheet music arrangement for a treble vocal ensemble. Visual and performance excerpts, of both the original performance and new arrangement, will support the discussion showing the step by step creative process during the pre-rehearsal phase. The composer will also describe the refinement process, introducing, and rehearsing the piece with the ensemble in preparation for a final performance product. The Keene State College Chamber Singers will serve as the demonstration choir for “Into the River”. The presentation will conclude with a composer-led discussion asking the conductor and singers about their reflections of the rehearsal and performance experience.
