Final answer:
Philip Glass is the composer who is known for using a minimalistic approach in his music, with a strong pulse, repeated rhythmic patterns, and limited tonal range.The correct option is C.
Step-by-step explanation:
The composer who used a minimum of musical materials to convey his message through a strong pulse, repeated rhythmic patterns, and limited instrumental tone and colors is Philip Glass.
Philip Glass is known for his minimalist approach to composition, utilizing repetitive structures and a reduced palette of sounds to create his distinctive style. In contrast, Arnold Schoenberg was known for his atonal music and twelve-tone scale, which represented a major break from traditional Western musical scales and harmonies.
Whereas Schoenberg's work is more closely associated with the avant-garde movements and is less accessible to mainstream audiences, Glass's minimalism has allowed for a broader appeal, with music that focuses on simplicity and clarity.
Artists like John Baldessari and composers like Steve Reich, John Adams, and Arvo Pärt are also associated with minimalism in various ways, but it is Glass's application of minimalism in his compositions that is most closely aligned with the use of limited musical materials described in the question.
While all four composers have contributed significantly to the minimalist genre, Philip Glass's focus on repetitive patterns and strong pulsations makes his work the most representative of the minimal materials approach.The correct option is C.
