The research found in this document will assist in a performer’s preparation of Dr. Eric Ewazen’s Concerto for Marimba and String Orchestra. In order to give an informed performance of the work, it is this author’s belief that an understanding of the collaboration between the composer and the premiering artist, Ms. She-e Wu, as well as the impact Ms. Wu’s artistry had on Dr. Ewazen is paramount. Also, knowledge of Dr. Ewazen’s compositional style, reference to his other works for percussion, and an understanding of the structure of the work will assist future performers in demonstrating a well-versed and rewarding performance of the piece. This study presents insightful interviews from both the composer and the premiering artist. These interviews offer a wealth of understanding into the composition and performance of the work. The performance practice suggestions offer tools to interpret and prepare the piece. Though the Concerto may be a challenge for many marimbists, this author hopes that future performers find the rewards in this well-constructed and exciting work after reading this document.
