Chalmers" RE Wilson's theories: I spoke with Erv on the telephone last night and he affirmed that the XH12 article is the best published account of his theories, but he also cautioned that he considers it primarily an introduction and explanation of the D'Allesandro keyboard tuning. I plan to visit Erv this weekend with Brian McLaren as Brian has more or less finished his current performing and recording project in San Diego and is returning to his home in Corvallis, Oregon the first of the month. If Erv has any thoughts to post, I'll do so ASAP. Mathew Puzan: While Yasser's book has been very influential on persons as diverse as Erv Wilson and Joel Mandelbaum, to my knowledge only Warren Burt has attempted to compose in Yasser's 12+7 system with harmony based Yasserian "hexads." Even Joel did not do so to any great extent in his dissertation, though he explored 19-tet pretty thoroughly from other standpoints. His 1961 dissertation "Multiple Division of the Octave and the Tonal Resources of 19 Tone Temperament" is a classic in the field. Although it was hearing the tape of Mandelbaum's 19-tet compositions that made Ivor Darreg aware of the distinct "moods" he claimed were associated with different ET's and induced him to explore ET systems beyond 12 and 24, Darreg was unsympathetic to Yasser's approach and notation. Even Yasser himself apparently did not compose in his system, though he did have the opportunity once to tune two pianos to 19-tet and hear it (personal communication). If you have had any experience composing in this style, I'd love to hear the results. --John Received: from eartha.mills.edu [144.91.3.20] by vbv40.ezh.nl with SMTP-OpenVMS via TCP/IP; Thu, 25 Jan 1996 21:35 +0100 Received: from by eartha.mills.edu via SMTP (940816.SGI.8.6.9/930416.SGI) for id MAA11888; Thu, 25 Jan 1996 12:34:58 -0800 Date: Thu, 25 Jan 1996 12:34:58 -0800 Message-Id: Errors-To: madole@ella.mills.edu Reply-To: tuning@eartha.mills.edu Originator: tuning@eartha.mills.edu Sender: tuning@eartha.mills.edu
