Indiana has a big music school. This style guide is primarily for dissertations, papers and other academic publications.
"The faculty of the IU Composition Department recognizes that there is not uniform field-wide agreement about many notational issues composers face . . . The overriding goal of this guide is clarity of musical intent and professionalism."
