The range of saxophones extends from the sopranino downwards to include a contrabass instrument. Sax's influence as an instrument inventor reaches beyond the saxophone. Saxhorns and rival instruments inspired by his designs fuelled the 19th-century English brass band movement. Sax also developed the modern bass and contrabass clarinet.
