We examined the content of the 2002 and 2004 National Biennial In-Service Conferences of MENC: The National Association for Music Education; the 2002 and 2004 Midwest Clinic: An International Band and Orchestra Conferences; the 2002 and 2004 Orff-Schulwerk Conferences; and the 2003 and 2005 American Choral Directors Association Conventions. Each of the 2,302 sessions was examined and classified according to category, subject area, and focus. The largest proportion of categories of sessions at the MENC (74.2%), Midwest (47.5%) and Orff-Schulwerk (80.3%) conferences was education, while performance (56.9%) was the largest proportion at ACDA. The predominant subject areas within education were performance for ACDA (53.3%) and Midwest (42.8%), general music (47.1%) for Orff-Schulwerk, and industry (42.3%) for MENC. The proportion of industry to non-industry sessions at MENC was more than double any of the other conferences examined. (Contains 2 figures and 4 tables.)
