As a composer, i agree with Ned Rorem that there really is no such thing. Minimalism, atonality, serialism, etc. are not really new. Check into music history! Ned Rorem thinks the only real change in "classical" music is a constant swing of the pendulum between emphasizing the intellectual and logic or the emotional and intuitive, if I understand him correctly. The past is in the present, and vice-versa. Ancient Greek modes being used in "modern" music, "aleatory" being retrieved from the Middle Ages or earlier, Medieval isorhythm being revived, etc. Check out the article by Terry Teachout, music critic of the Wall St Journal, drama critic for the N.Y. Times, member, National Council of the Arts, in the magazine "Commentary" for July-Aug. 2005. In this groundbreaking article, " The Return of the Romantics "he blasts the arrogant claims of the 20th Century serialists, minimalists etc. He quotes author Walter Simmons, who is writing a six- volume work called "Voices In the Wilderness", about Hanson ,Creston ,Rorem, and others who kept their sanity during the 20th Century takeover of "serious" music by Avante-Gardists who controlled most of the funding, etc. for new works. Simmons has a website, www. walter-simmons.com, with digital sound-files of the banned (for performance-funding) Romantic and neglected composers of that era and today.
I remember how when I was a composition student in the conservatory, I was required to write atonal and "modern" music, and was told I could not write in my natural way, which was very tonal/modal and classical, and somewhat neo-Romantic at times! Now the tide is turning. The neglected composers are coming back and the minimalist and other fashionable types will be seen by music history for what they are-- a decadent manifestation, of aberrant techniques used to attract attention or shock. (Or do they express and help create a decadent society?) ( Remember how the Greeks felt music creates patterns in society for better or worse!)
Some of these techniques ARE interesting, but they were used long ago, also. Aleatory music and serialized were used in the Middle Ages, if you check into the Harvard Dictionary of Music and Grove's also. (Talas, isorhythm, etc.) My only real requirement for a composer is that he/she be REAL, or have something to say that leaves us with a catharsis, or upliftment, or an insight on life, not parodies of life AND music, twisted art for twisted people. Young composers have been "sold a bill of goods" about the importance of being "modern" or "experimetnal". I have studied the "moderns" and DO find a few good or great ones. Charles Ives is great, profound even at his wildest, dissonances, etc. Xenakis and Messiean, also and a few others, such as Harry Partch .
Outrage anyone? Agree, disagree? Would like to hear from you out there. Del Hudson, M.M.
