The English tradition of semi-opera, to which "The Fairy-Queen" belongs, demanded that most of the music within the play be introduced through the agency of supernatural beings, the exception being pastoral or drunken characters. All the masques in "The Fairy-Queen" are presented by Titania or Oberon. Originally act 1 contained no music, but due to the work's enormous success it was revived in 1693, when Purcell added the scene of the Drunken Poet and two further songs later on in the work; "Ye gentle spirits of the air" and "The Plaint". As noted above, each masque is subtly related to the action in the play during that particular act in a metaphorical way. In this manner we have Night and Sleep in act 2, which is apt as that act of the play consists of Oberon's plans to use the power of the "love-in-idleness" flower to confuse various loves, and it is therefore appropriate for the allegorical figures of Secrecy, Mystery "et al." to usher in a night of enchantment. The masque for Bottom in act 3 includes metamorphoses, songs of both real and feigned love, and beings who are not what they seem. The Reconciliation masque between Oberon and Titania at the end of act 4 prefigures the final masque. The scene changes to a Garden of Fountains, denoting King William's hobby, just after Oberon says "bless these Lovers' Nuptial Day". The Four Seasons tell us that the marriage here celebrated is a good one all year round and "All Salute the rising Sun"/...The Birthday of King Oberon". The kings of England were traditionally likened to the sun (Oberon = William. Significantly, William and Mary were married on his birthday, 4 November.). The Chinese scene in the final masque is in homage to Queen Mary's famous collection of china. The garden shown above it and the exotic animals bring King William back into the picture and Hymen's song in praise of their marriage, plus the stage direction bringing (Mary's) china vases containing (William's) orange trees to the front of the stage complete the symbolism.
