In March 2012, I made a presentation to the Southwest Chapter of the American Choral Directors Association entitled, Loop the Loop! Spinning Interactive Circles to Develop Choral  Sound, Engage Awareness, and Explore Artistry.

Materials for the presentation, including handouts, vocalizes, repertoire and powerpoint file, can be accessed on my old blog at:
