Woody Herman Shaw Jr. was an American jazz trumpeter, flugelhornist, cornetist, composer, arranger, band leader, and educator. Shaw is widely known as one of the 20th century's most important and influential jazz trumpeters and composers. He is often credited with revolutionizing the technical and harmonic language of modern jazz trumpet playing, and is regarded by many as one of the major innovators of the instrument. He was an acclaimed virtuoso, mentor, and spokesperson for jazz and worked and recorded alongside many of the leading musicians of his time.

The flugelhorn, also spelled fluegelhorn, flugel horn, or flügelhorn, is a brass instrument that resembles the trumpet and cornet but has a wider, more conical bore. Like trumpets and cornets, most flugelhorns are pitched in B♭, though some are in C. It is a type of valved bugle, developed in Germany in the early 19th century from a traditional English valveless bugle. The first version of a valved bugle was sold by Heinrich Stölzel in Berlin in 1828. The valved bugle provided Adolphe Sax with the inspiration for his B♭ soprano (contralto) saxhorns, on which the modern-day flugelhorn is modelled.
