Final answer:
Contemporaneous music theorists and observers may have had a near-sighted view of music history, particularly regarding the acknowledgment and discussion of polyphony earlier than a generation, due to several reasons. Firstly, the historical context and cultural biases of the time played a significant role. Secondly, the lack of access to written notation and theoretical practices could have hindered the understanding and recognition of polyphony. Lastly, the emergence of modernist movements in the early twentieth century led to a deliberate break from traditional musical practices.
Step-by-step explanation:
Contemporaneous music theorists and observers may have had a near-sighted view of music history, particularly regarding the acknowledgment and discussion of polyphony earlier than a generation, due to several reasons Firstly, the historical context and cultural biases of the time played a significant role. Many music theorists and observers were influenced by the dominant musical traditions of their era, which focused on monophonic and homophonic music. Polyphony, on the other hand, was viewed as complex and unconventional, challenging the established norms and expectations. Secondly, the lack of access to written notation and theoretical practices could have hindered the understanding and recognition of polyphony. Before the development of a comprehensive notational system during the Medieval period, musical compositions were often transmitted orally. This oral tradition might have limited the preservation and dissemination of polyphonic music, making it less visible to contemporary theorists and observers. Lastly, the emergence of modernist movements in the early twentieth century led to a deliberate break from traditional musical practices. Composers and musicians sought to shatter musical traditions, favoring new experimental styles that differed from the polyphonic compositions of the past. This shift in musical trends and preferences further contributed to the near-sighted view of music history.
