Below you will find links to some of the material that I present to my students in different courses.  I have converted them so that they can be viewed online using Internet Explorer (unfortunately you have to use Internet Explorer or the pages won't display correctly and animations won't work).

To view a presentation, open this page in Internet Explorer and click on one of the links below.  When the presentation comes up, click on "Slide Show" in the lower right-hand corner of the window.  Then press the space bar to step through the presentation.  To stop the presentation press "Esc."

Newly updated:  I have incorporated the sound waves I generated for the comparison of Equal Temperament and Just Intonation into my PowerPoint slides.  These have recently been posted (in "Music and Extra Slides").  Students have asked me about this in the past, and now they are here!

IMPORTANT: These slides are here for the benefit of students and my fellow professors.  They are provided as is, with no guarantees.  It takes effort to edit and convert these files for the web, so I will not keep them regularly updated.  They do not include pictures or tables for which I do not own the copyright.  As such, what you find here will differ somewhat from what I show in class.  While I don't mind requests to update these files, I may not have time to accommodate them. 

I once had a student who was very critical of me because these slides were incomplete.  Please remember that this is an extra effort to help students and other professors.  The amount of time it takes to post the slides is large compared to the benefit I think that they give to students.  If I hear excessive complaining about out of date, incomplete, or even incorrect slides in any class, I will remove this page from the web.
