Two scenes of parting dominate the dramatic plan of this Act, that of Rodolfo and Mimi, and that of Marcello and Musetta. They are cleverly contrasted. Very pathetically does Mimi's "addio senza rancor" come from the depths of her simple little heart, while the end is foreshadowed by the hacking cough which frequently chokes her utterances. Musetta is taken to task by Marcel for flirting, and off she goes after a strongly dramatic duet, which for characterisation and force is one of the most distinctive numbers in the opera; and after her exit, in a fury, Mimi and Rodolfo appear to agree, indicated by the last phrases of their tender duet, to continue together, for yet a space, in the old relations.
In the fourth Act we are back in the attic; and the quartet of Bohemians are once more struggling with the problem of keeping body and soul together. Two of them, Rodolfo and Marcel, at any rate, are lonely, for Mimi has been taken up by a viscount, and Musetta, dressed in velvet--through which, as Rudolfo tells Marcel, she cannot hear her heart beat--is riding in a carriage. But with all their troubles they keep a stout heart and are able to jest over the herring and rolls which Schaunard and Colline bring in for dinner. They dance and romp, and play the fool in the lightest hearted manner until Musetta suddenly breaks in upon their pretended jollity. The end is reached rapidly. Mimi has come home to die, and this she does after an intensely sad, simple and moving scene, stretched, as they placed her, on Rodolfo's hard little bed. Infinitely touching is Mimi's reference, in her last words, to the song which Rodolfo sang in the opening Act. She begins _Che gelida manina_ only to break off in a fit of coughing. Marcello has gone out to fetch a doctor and Musetta brings a muff to warm the dying girl's fingers. Mimi's spirit passes away however before aid can be brought to her, and the pathos of the situation is intensified by the silence in which it takes place. It is Schaunard who whispers to Marcello that she is dead. To Rodolfo's last despairing cry of "Mimi! Mimi!" as he realises that his loved one is no more, does the curtain fall.
There is little to point to in the music save its chief and outstanding feature, its continuity. In this the whole charm and strength of the work lies. Orchestrally, the score of _La Bohème_ is a beautifully polished one, not so symphonically complete as _Manon_ for instance, but essentially individual. For fulness as a constructional background one may point to the orchestration of the duet in the first Act; for daintiness of effect, the use of harmonics on the harp against the muted strings in Musetta's waltz-song; while many happy touches are seen all through, such as the xylophone and muted trumpets at the toy-sellers' entrance in the café scene; or again, the striking passage in fifths at the opening of the third Act, given to the harp and flutes over the 'cellos playing _tremolo_. The orchestra employed is the usual large modern orchestra, with a piccolo, glockenspiel and xylophone. Considerable use is also made of the division of the 'cellos, in many places, into three.
