There are four bars in a chorus. Nanton's style of play is often called " plunger mute." The sound of the accompanying trombone section during his solo is muted and staccato.
What is chorus?
A group of singers who perform together in a choir. The music composed especially for such a combination to perform is known as choral music. Both the chamber music repertoire, which dates from the Middle Ages to the Present, and the popular music repertoire are both available for choir performances. The conductor of the majority of choirs directs the performance results with arm, palm, and facial gestures. While a chorus performs in cinemas or concert halls, the term "choir" is frequently used to refer to groups associated with a church (regardless of whether they actually take up the quire). However, this distinction is indeed not rigid. Choirs may perform unaccompanied or with the help of an orchestra, piano, pipe organ, small ensemble, or other musical instrument.
These supporting accompaniments give harmonic and rhythmic support to Nanton's solo by providing a steady pulse and a bed of sound for him to solo over.
