sung by Desirée. As Sondheim explains, Desirée experiences both deep regret and furious anger: Meter and key The song was originally performed in the key of D major. The song uses an unusual and complex meter, which alternates between and . These are two complex compound meters that evoke the sense of a waltz used throughout the score of the show. Sondheim tells the story: When I worked with Leonard Bernstein on West Side Story, one of the things I learned from him was not always necessarily to think in terms of 2-, 4- and 8-bar phrases. I was already liberated enough before I met him not to be sticking to 32-bar songs, but I tend to think square. I tend to think ... it's probably because I was brought up on mid-19th and late-19th century music, and you know it's fairly square; there are not an awful lot of meter changes. You often will shorten or lengthen a bar for rhythmic purposes and for energy, but ... when you switch in the middle [of a song], particularly when it's a modest song, when you're not writing an aria, you know ... [I mean,] if you're writing something like Sweeney Todd, where people sing at great length, you expect switches of meter, because it helps variety. But in a little 36- or 40-bar song, to switch meters around is almost perverse, because the song doesn't get a chance to establish its own rhythm. But the problem is, what would you do?: Would you go, "Isn't it rich? (two, three) Are we a pair? (two, three) Me here at last on the ground (three), you in mid-air." Lenny [Bernstein] taught me to think in terms of, "Do you really need the extra beat (after 'ground') or not." Just because you've got four bars of four, if you come across a bar that doesn't need the extra beat, then put a bar of three in. So ... the 9 [beat bars] and 12 [beat bars] that alternate in that song were not so much consciously arrived at as they were by the emotionality of the lyric. Styles "Send in the Clowns" is performed in two completely different styles: dramatic and lyric. The dramatic style is the theatrical performance by Desirée, and this style emphasizes Desirée's feelings of anger and regret, and the dramatic style acts as a cohesive part of the play.
