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 (4 7.5%) 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.Among the functions of professional organizations is supporting the interests, focuses, directions, and concerns of their members through activities such as advocacy, publications, and the coordination of professional conferences. Thus, the content of these activities might be regarded as an indicator of the interests and concerns of a professional organization, and these activities may be amenable to systematic inquiry. Jacobs and McFarlane (2005) declared that, Most, if not all, researchers attend conferences as a part of their practice, and yet it is an under-researched activity. Little attention has been paid either to developing a theoretically informed understanding of conference practice as knowledge building, or to assessing the extent to which conferences are successful. (p. 317)While there is a dearth of such literature, a few investigations of conferences have been undertaken.
