Being an engineer, I also appreciated your insight as to why = these temperaments work from a technical basis. Thanks again, Don Bee, Jr. -----Original Message----- From: Ron Koval [<A = HREF="mailto:drwoodwind@hotmail.com">mailto:drwoodwind@hotmail.com</A>= ] Sent: Thursday, June 21, 2001 08:43 AM To: pianotech@ptg.org Subject: first chapter presentation Hi everyone Last Tuesday was my first presentation at our Chicago = chapter meeting. I survived! (Actually I had a great time, everyone = was receptive and asked good questions) Of course, as graphman, I chose to present = "seeing" the temperaments.  Did a quick intro including why we need to temper = intervals, and used a very broad paintbrush to explain differing tuning = systems.(meantone, well)  Progressed on to an introduction of graphing the major thirds = (how many cents from pure) to visually get an indication of how a = temperament will 'play'.  Introduced the idea of diluting temperaments for = everyday use.  I had earlier tuned 5 pianos for comparison: 1.  Prinz well, diluted to a 60% strength 2.  Penny temperament (one cent maximum offset. = Created to show how much     a one cent difference can = make) 3.  Coleman 11 4.  Moore well 5.  Equal beating Victorian (Real close to what = Bill Bremmer uses) Everyone had about 40 minutes to travel from room to = room and get a first hand impression of the differences and similarities = between these temperaments. We finished with a short discussion about beats, = equal beating, and how we hear a difference between playing a triad versus = just playing a major 3rd. (progressing through the circle of fifths) I saw a few glazed eyes during the presentation (or = maybe LaBorn has figured out how to sleep with his eyes open ((just kidding, = John!))) but I think most people were able to get something out of the = presentation. I left them all with a handout of graphs and offsets = of a bunch of the more common alternate temperaments.  So, guys and = gals, go forth and experiment!
