The clarinet quintet Alchymia by Thomas Adès is woven from four threads leading out of the alchemical world of Elizabethan London. This is the full score. Parts are also available. 

I. A Sea-Change (...those are pearls...)
II. The Woods So Wild
III. Lachrymae
IV. Divisions on a Lute-song: Wedekind’s Round

The movement titles refer to:

• William Shakespeare, The Tempest 1611 - the  king’s eyes transformed by the sea into pearls.
• The Woods So Wild 1612 - Tudor popular song transformed by William Byrd into keyboard divisions (variations).
• Lachrymae 1600 - (Tears) - John Dowland’s lute-song, which he transformed into viol consort Fantasias.
• Divisions on a Lute-song: Wedekind’s Round - variations on the playwright Frank Wedekind’s Lautenlied (lute-song), which is played by clarinet, imitating a barrel-organ in the London street, in the final scene of Alban Berg’s opera Lulu.

Alchymia was written for Basset Clarinet in A, but may be performed on a standard Clarinet in A using the ossia notes throughout the score.
