and the chorus takes up the jovial refrain in the same temper. The aria itself is well known as the laughing song. Indeed, both aria and chorus are full of unrestrained mirth, and go laughingly along in genuine musical giggles.[28] The effect is still further enhanced by the next aria for Allegro ("Come and trip it as you go"), a graceful minuet, which is also taken by the chorus. After a recitative by Penseroso ("Come, pensive Nun"), and the aria, "Come, but keep thy wonted State" the first Penseroso chorus occurs ("Join with thee calm Peace and Quiet"), a short but beautiful passage of tranquil harmony. Once more in recitative Allegro bids "loathed Melancholy" hence, and then in the aria, "Mirth, admit me of thy Crew," leading into a chorus, sings of the lark, "startling dull Night" and bidding good-morrow at his window,--a brilliant number accompanied with an imitation of the lark's song. Penseroso replies with an equally brilliant song ("Sweet Bird, that shuns't the Noise of Folly"), in which the nightingale plays the part of accompaniment. Another aria by Allegro ("Mirth, admit me of thy Crew") gives an opportunity for a blithe and jocund hunting-song for the bass, followed by one of the most beautiful numbers in the work ("Oft on a Plat of rising Ground") sung by Penseroso, in which the ringing of the far-off curfew, "swinging slow, with sullen roar," is introduced with telling effect. This is followed by a quiet meditative aria ("Far from all Resorts of Mirth"), when once again Allegro takes up the strain in the two arias, "Let me wander not unseen," and "Straight mine Eye hath caught new Pleasures." The first part closes with the Allegro aria and chorus ("Or let the merry Bells ring round"), full of the very spirit of joy and youth; and ending with an exquisite harmonic effect as the gay crowd creep to bed, "by whispering winds soon lulled to sleep." The second part begins with a stately recitative and aria by Penseroso ("Sometimes let gorgeous Tragedy"), followed by one of the most characteristic arias in the work ("But O, sad Virgin, that thy Power might raise!") in which the passage, "Or bid the soul of Orpheus sing Such notes as warbled to the string Drew iron tears down Pluto's cheek," is accompanied by long persistent trills that admirably suit the words. The next number ("Populous Cities please me then") is a very descriptive solo for Allegro, with chorus which begins in canon form for the voices and then turns to a lively movement as it pictures the knights celebrating their triumphs and the "store of ladies" awarding prizes to their gallants. Again Allegro in a graceful aria sings, "There let Hymen oft appear." It is followed by a charming canzonet ("Hide me from Day's garish Eye") for Penseroso, which leads to an aria for Allegro ("I'll to the well-trod Stage anon"), opening in genuinely theatrical style, and then changing to a delightfully melodious warble at the words,--
