Seiber's music is eclectic in style, showing the influences of Bartók, Kodály, Schoenberg, serialism, jazz, and folk song, and his output includes film and lighter music. Often, individual pieces use a combination of these influences. For instance, the two "Jazzolettes" for wind and percussion (1929 and 1932, composed in Frankfurt) make liberal use of jazz effects and rhythms that displace the bar lines, but also show his first explorations of twelve note techniques. The late work "Permutationi a Cinque" (1948) also for wind ensemble, uses permutations of motifs that eventually come together to reveal a twelve-tone series - but it is all done with lightness and humour.
