21. [Nor that is not.] Double negatives are common in S.
22. [The vaulty heaven.] Cf. K. John, v. 2. 52: "the vaulty top of heaven;" and R. of L. 119: "her vaulty prison" (that is, Night's).
29. [Division.] "The breaking of a melody, or its descant, into small notes. The modern musician would call it variation" (Elson). Cf. 1 Hen. IV. iii. 1. 210:—
"Sung by a fair queen in a summer's bower,
With ravishing division, to her lute."
The word is a quadrisyllable here.
31. [The lark,] etc. The toad having beautiful eyes, and the lark very ugly ones, it was a popular tradition that they had changed eyes. (Warburton).
33. [Affray.] Startle from sleep; as Chaucer in Blaunche the Duchess (296) is affrayed out of his sleep by "smale foules" (Dowden).
34. [Hunt's-up.] The tune played to wake and collect the hunters (Steevens). Cf. Drayton, Polyolbion: "But hunts-up to the morn the feather'd sylvans sing;" and again in Third Eclogue: "Time plays the hunts-up to thy sleepy head." We have the full form in T.A. ii. 2. 1: "The hunt is up, the morn is bright and grey." The term was also applied to any morning song, and especially one to a new-married woman. Cotgrave (ed. 1632) defines resveil as "a Hunts-up, or morning song, for a new-maried wife, the day after the mariage."
