@section Contemporary music

From the beginning of the 20th Century there has been a massive
expansion of compositional style and technique.  New harmonic
and rhythmic developments, an expansion of the pitch spectrum
and the development of a wide range of new instrumental
techniques have been accompanied by a parallel evolution and
expansion of musical notation.  The purpose of this section is
to provide references and information relevant to working with
these new notational techniques.
