Musicological research this, into the texture of meanings behind the score. Through history, through all aspects of music (composition, singing, intrumental music, dance types, orchestral music, opera,) he surveys the interpretation and reinterpretation of the originator's meanings. His scope is immense -- from the early classic to the future of television, with jazz and swing a passing phase. For technicians, workshop musicians, and the few laymen highly versed in musical appreciation. He closes with an analysis from his peak, of The Star Spangled Banner.
