Styles of king Lear act 4 scene 7

When Lear is reunited with his beloved Cordelia at the end of the Act, it seems, for just a moment, that his sanity has been restored, perhaps by copious amounts of sleep. He recognizes Cordelia immediately (“I think this lady / To be my child Cordelia) (4.7.69-70)), and the return of music signals a sense of harmony in the world. It’s clear in this section that all the characters are hurtling toward their final realizations, and that the play’s psychological and physical plotlines are drawing to a close.
