Final answer:
The development of a repertoire of standing classics by past composers is attributed to their recognized musical quality and historical significance, enabled by advances in music printing technology and change in the audience demographics in the Romantic era. The classics provided foundational works for future music education and performance, although contemporary efforts are expanding this repertoire to include underrepresented composers based on the merit of their compositions.
Step-by-step explanation:
Development of a Repertoire of Standing Classics
One reason for the development of a repertoire of standing classics by past composers is the shared understanding of musical quality and historical significance. Over time, the evolution of music printing technology, such as the Gutenberg press, facilitated the widespread distribution of music and musical theory, which increased demand for music as both entertainment and an educated activity. This led to the popularization of works from composers like Palestrina, Lassus, Victoria, and William Byrd whose music became exemplary of the polyphonic style of the sixteenth century.
As the middle class rose, so did the public concerts and festivals featuring compositions by Romantic composers who continued to build upon the forms and rules established by classical composers like Haydn, Mozart, and particularly Beethoven. These composers emulated the classicists while others favored innovation and challenged established norms, leading to the diversification and enrichment of the music we now consider classical. Berlioz, Strauss, and Wagner were notable for such progressive work.
Further appreciation of these classical works grew as part of music education where students analyzed them in depth. However, there has been a push to also acknowledge and include quality repertoire from underrepresented composers, championing their compositions for their exceptional qualities without the need to mention race or gender. This approach may lead to a more diverse and inclusive repertoire that still honors the high standards of classical music excellence.
