The psychological laboratory in the University of Iowa is conducting a number of studies in the psychology of music, laying scientific foundations for the theory and practice of the art. To make these scientific findings in the interpretation of vocal and instrumental music as actually rendered, it has been necessary to design a scientific type of musical score. This has been built as closely as possible in musical terminology but is so designed as to show in great detail how the notes are actually sung and played. For example, instead of indicating the note "C" by the usual musical notation, a graph is substituted showing exactly how the tone was rendered. Parallel with this is a method of showing changes in loudness and stress in the rhythm and another notation to indicate the tone quality.
