Answer
Walton was widely regarded as a modernist composer during the early part of his career. His music of this period, such as the Façade Suite and the Viola Concerto, was characterized by its use of dissonance, polytonality, and other modernist techniques. However, as his career progressed, Walton's music became more tonal and less experimental. By the time of his death in 1983, he was considered to be a conservative composer.
