The Well Tempered Timpani

Today I was doing remedial searches for images of various percussion instruments when I stumbled across an excellent document titled The Well Tempered Timpani written by Richard K. Jones. I believe I've seen this document before, but I haven't written about it. There is excellent information in this document that any timpanist, percussionist, or physicist should be aware of. I highly recommend this reading and will report back if it yields any noticeable results.
