Subject: Re: Perfect harmony: A mathematical analysis of four historical From: Denis Donovan <dmdonvan(at)IX.NETCOM.COM> Date: Sun, 17 Oct 2004 11:16:12 -0400I haven't read the paper Frédéric Maintenant refers to in his post below, and I'm not sure that I would be properly qualified to pass judgment on it, in any case. But I'm a bit concerned about the elitist ageism it seems to reflect. Many scientific minds have produced exquisite and immensely productive thinking at a very early age. Indeed, many minds seem to lose their creative élan after an extended adolescence -- a bit like some recent athletes. And -- in this case, sticking to the French -- writers from Rimbaud to Sagan certainly made their mark before 20. As we all know, Mozart composed many early pieces, notably, at age 11,the piano concerti K. 37, 39. 40 and 41. In 1775, at age 19, Mozart composed all five of his violin concerti. Anyone interested in following the prodigious progression of the early piano concerti, can do so most enjoyably by listening to the first CDs of the 12-CD Volume 7 of the Philips Complete Mozart Edition (442507-2). For a less ipseitic example, consider Mendelssohn's 12 String Symphonies, all of which he wrote at 14. I prefer Mendelssohn as an example because he was so sensitive to, and appreciative of, the music of other composers and did much to make it accessible. Then we have the American composer Donald Keats, currently professor at the University of Denver. Thirty years ago, in the fall of 1964, I made a passing remark to Keats about "student compositions." Keats smiled and pointed out that his two String Quartets were, at the time, the first string quartets to be published by Boosey & Hawkes since Stravinsky. "Needless to say," he added, "I didn't tell the publisher that I wrote them while still a student because Boosey & Hawkes doesn't publish 'student works.'" So, for whom does "the use of word such as 'harmony' or 'mathematical analysis' [NOT] have the same signification whether you are at high school or in a research team"? Probably not for those who aren't being creatively productive at a relatively early age. When genuinely good thinking -- or, for that matter, good writing or good composing or good performance -- occurs at age 15, is it any different than genuinely good thinking or good writing or good composing or good performance at age 79? Ironically, some people appear no more cognitively capable of producing memorable coherent musical form at 79 than they were at age 15. (Memorability, I suggest, is, or ought to be, a key concept in musical cognition research.) Just a reaction -- and a thought.
