One Hand, One Heart

The tune was originally composed for an unused song in Candide,^[1] called "One". The original tune comprised just a single dotted note per bar, which Sondheim was loath to write lyrics for, as he would have to write all single syllable words, so he wrote lyrics making fun of the tune to persuade Bernstein to give him the extra notes.^[2] Sondheim later wrote of the final product:

Lenny had written only one note for each bar, so each word lay there, heavy and detached from the word that followed. It was like a sequence of anchors. ... As in "Somewhere" the tune hamstrings the lyricist by virtually precluding the use of any two-syllable words, which sound ridiculous when stretched out so slowly. But Lenny was very fond of the melody and wanted to use it for the Balcony Scene, so I asked him merely to give me a couple extra quarter-notes per bar, which didn't change the melodic outline. The paucity of notes did have one virtue: it made me write simply. A little too simply, but still...^[3]

Philip Brophy analysis the song's context within the musical:

This number extends the playing-out of social rituals as in the previous number. Here Tony and Maria perform a symbolic marriage because such an actual ceremony is a 'social' impossibility. This reinforces their relationship as being 'above' their social reality, accented by the whole notion of them with their heads 'up in the clouds'. Throughout this number they 'harmonize' with one another and eventually resolve those harmonies into unison, symbolizing their 'oneness' with one another. Note how their call-response itself is a recreation of the vow exchanges in a marriage ceremony. Note also how at the end of the number, the melodic motif of "Maria" slightly upsets the harmonic resolution. This motif – which it must be remembered alludes to Tony's desire to get it on with Maria, and which therefore constitutes a social transgression which works to move the plot along to end tragically – symbolically suggests that their wedding will not take place because 'it shouldn't happen'.^[4]
