I propose a session in which we discuss, share, and perhaps create (or agree to create) some communal resources (in-class activities, flashcards, analyses, games, homework assignments, you name it), for use in conjunction with the Open Music Theory (OMT) online textbook.
I for one am taking the plunge and making OMT my primary resource for Freshman-level music theory in the 2015-2016 academic year, with no required textbook for purchase. (I’ll also use www.musictheory.net for fundamental “flashcards” and additional lessons/exercises.) After 14 years with the same text+workbook (from undergrad through professor!), I’ve grown accustomed to having lots of written assignments and short musical examples at my fingertips. I understand that OMT is designed to be light on explanations and literature-based musical examples, freeing the instructor to fill in these gaps with literature, analyses, activities, etc. as she/he sees fit. I’m wondering, how are my fellow “Open” theory teachers handling this transition? What resources are you drawing on, and what do you wish was out there?
I am eager to share (Creative Commons Attribution) any activity/workbook/assignment-type material I generate this year, and would love to collaborate with others to help in this task, possibly eventually creating an editable Workbook or Activity Resource to go along with this online text. This session will culminate with Google Docs lists of the following:
1.) Supplementary resources already existing,
2.) Resources authors plan to create in the upcoming year, and
3.) (hopefully) Plans to collaborate on a helpful, educational, and time-saving Workbook and Activity Resource for use by the music theory community at large.
