Almost all Spinner's music was written according to the
twelve-tone technique (on which he also wrote a significant textbook,
A Short Introduction to the Technique of Twelve-tone Composition, published 1960). His early works, up to and including the
Zwei kleine Stücke, are clearly influenced by
Berg and middle-period Schoenberg. From the mid-1930s the general idiom, expressive intensity, dramatic economy and impeccable craftsmanship bear witness to his admiration for his teacher Webern – and, through Webern, for the whole Austro-German tradition from
Bach onwards. Spinner himself carried that tradition a stage further. While retaining the purity and thematically essentialized textures of Webern, his works show a concern for larger and bolder gestures than Webern's norm. In his later music, beginning with the sonatina for piano, the expressive pressure applied to strict motivic working results in a wholly individual style of almost explosive force. ==References==
