friend is blowing in the wind")—whereas 'chorus' shall refer to a discrete form part (as in Yellow Submarine: "We all live in a..."). According to the musicologists Ralf von Appen and Markus Frei-Hauenschild, In German, the term, "Refrain," is used synonymously with "chorus" when referring to a chorus within the verse/chorus form. At least one English-language author, Richard Middleton, uses the term in the same way. In English usage, however, the term, »refrain« typically refers to what in German is more precisely called the »Refrainzeile« (refrain line): a lyric at the beginning or end of a section that is repeated in every iteration. In this usage, the refrain does not constitute a discrete, independent section within the form. In jazz Many Tin-Pan Alley songs using thirty-two bar form are central to the traditional jazz repertoire. In jazz arrangements the word "chorus" refers to the same unit of music as in the Tin Pan Alley tradition, but unlike the Tin Pan Alley tradition a single song can have more than one chorus. Von Appen and Frei-Hauenschild explain, "The term, 'chorus' can also refer to a single iteration of the entire 32 bars of the AABA form, especially among jazz musicians, who improvise over multiple repetitions of such choruses." Arranger's chorus In jazz, an arranger's chorus is where the arranger uses particularly elaborate techniques to exhibit their skill and to impress the listener. This may include use of counterpoint, reharmonization, tone color, or any other arranging device. The arranger's chorus is generally not the first or the last chorus of a jazz performance. Shout chorus In jazz, a shout chorus (occasionally: out chorus) is usually the last chorus of a big band arrangement, and is characterized by being the most energetic, lively, and exciting and by containing the musical climax of the piece. A shout chorus characteristically employs extreme ranges, loud dynamics, and a re-arrangement of melodic motives into short, accented riffs. Shout choruses often feature tutti or concerted writing, but may also use contrapuntal writing or call and response between the brass and saxophones, or between the ensemble and the drummer. Additionally, brass players frequently use extended techniques such as falls, doits, turns, and shakes to add excitement.
