This chapter considers general issues that apply to the whole show: the question of genre, features of the musical language, the use of the orchestra, and the process of orchestrating a Broadway show. Leonard Bernstein then turned to the role of dancing in Broadway shows: Ever since 1936, when Rodgers and Hart came up with On Your Toes, dancing has come into its own as a plot-furthering medium. Bernstein himself often stressed the importance of the interval of the tritone in the score, and its use of sharpened fourths in general. The interval of an augmented fourth in the melody, or a sharpened fourth present in the melodic line or in the harmony, can be found in every one of the examples. Jack Gottlieb describes ambiguities between major and minor thirds as being characteristic of synagogue music, and of early Yiddish secular song.
