Three original software programs utilizing improvisation and live sampling are presented here, along with a discussion of aesthetic issues raised by each. They are entitled Zur Elektrodynamik bewegter Musiker, Motet, and Gamepad Sampler. These programs vary in the degree of required interaction and in the kind of user control. They are each studies in imitative counterpoint through live sampling, with an approach seeking elegance before solutions. Because of the improvisational nature of these works, there is no standard musical score. Instead the complete Max/MSP source code and a sound recording of performances making use of these programs in varied situations are included. A discussion of issues raised by these works includes aesthetics, ontology, performance, and the role of the composer. Non-interactive indeterminate compositions are ontologically thin, because some composerly agency is required of the performer. An interactive work can be ontologically substantial if it makes distinct and significant contributions to performance, even though it may not make sound on its own. Although reproducibility reduces ontology and eliminates aura, live sampling within a performance can deepen the ontology of the performance by recontextualizing previous events, reframing the original event as the first reference to an abstract musical idea that lies outside …

This study traced the evolution of experiential education in American history museums from 1787 to 2007. Because of a decline in attendance, museum educators need to identify best practices to draw and retain audiences. I used 16 museology and history journals, books, and archives of museums prominent for using the method. I also interviewed 15 museum educators who employ experiential learning, one master interpreter of the National Park Service, and an independent museum exhibit developer. Experiential education involves doing with hands touching physical materials. Four minor questions concerned antecedents of experiential learning, reasons to invest in the method, the influence of social context, and cultural pluralism. Next is a review of the theorists whose works support experiential learning: Dewey, Piaget, Vygotsky, Lewin, Bruner, Eisner, Hein, and David Kolb plus master parks interpreter Freeman Tilden. The 8 characteristics they support include prior experiences, physical action, interaction with the environment, use of the senses, emotion, social relationships, and personal meaning. Other sections are manifestation of experiential learning, transformation of history museums, and cultural pluralism in history museums. The research design is descriptive, and the procedure, document analysis and structured interview. Findings are divided by decades after the first 120 years. Social context, …
