Death, as a subject, has been treated extensively throughout history, both in literature as well as in music. The focus of Memento mori is to portray the inevitability of death through music. The first part of the document is an essay exploring the topic of death, its inevitability, unpredictability and the fragility of life. This section also includes a number of examples of composer's whose works have influenced the composition of the piece. The title of the work is meant to reflect that death catches up with all of us and that humans no matter how invincible they feel at certain stages of life will, eventually, succumb to death. The second part of the document is the notated orchestral score. The work is for full orchestra and solo violoncello. It is in three acts that loosely resemble three stages of life; Youth followed by life in adulthood and finally death. The work is not programmatic and the piece's formal structure varies from a traditional concerto, for although comprised of three distinct acts, there are no pauses between them. The entire work is meant to be dark and morbid and the specter of death looms throughout the piece.
