Scores and sketches, 1961-2002

The second series, Scores and Sketches, best depicts the full range of O'Reilly's career, beginning with student works from the 1960s and moving through his mature years until 2002. The documents show works in various state of completion, often recording early changes and conceptions. Although most works are for band, there are a few for other types of ensembles as well, including chamber, choral, and solo works.
