Mummerset refers to a fictional rustic English county, and more commonly, the English dialect supposedly spoken there. Mummerset is used by actors to represent a stereotypical English West Country accent while not being specific to any actual county.

The name is a play on words: it is a portmanteau of "mummer", a archaic term for a folk actor, and the name of the largely rural county of Somerset.

Mummerset draws on a mixture of characteristics of real dialects from the West Country, such as rhoticism, forward-shifted diphthongs, lengthened vowels, and voicing of consonants that are voiceless in other Englishes. "S" is replaced with "Z"; "F" is replaced with "V" It also uses perceived dialect grammar, replacing instances of "am", "are" and "is" with "be". The sentence "I haven't seen him, that farmer, since Friday" could be parsed in Mummerset as "Oi ain't zeen 'im that be varmer since Vroiday".

In King Lear, Edgar speaks in Mummerset when he fights Oswald:

Good gentleman, go your gait, and let poor volk pass. An ’chud ha’ bin
zwagger’d out of my life, ’t would not ha’bin zo long as ’tis by a vortnight. Nay, come not
near th’ old man; keep out, ’che vor ye, or Ise try whether your costard or my
ballow be the harder. ’Chill be plain with you.

Orlando Gibbons (baptised 25 December 1583 – 5 June 1625) was an English composer, virginalist and organist of the late Tudor and early Jacobean periods. He was a leading composer in the England of his day.

Gibbons was born in Cambridge and christened at Oxford the same year – thus appearing in Oxford church records.

Between 1596 and 1598 he sang in the Choir of King's College, Cambridge, where his brother Edward Gibbons (1568–1650), eldest of the four sons of William Gibbons, was master of the choristers. The second brother Ellis Gibbons (1573–1603) was also a promising composer, but died young. Orlando entered the university in 1598 and achieved the degree of Bachelor of Music in 1606.James I appointed him a Gentleman of the Chapel Royal, where he served as an organist from at least 1615 until his death. In 1623 he became senior organist at the Chapel Royal, with Thomas Tomkins as junior organist. He also held positions as keyboard player in the privy chamber of the court of Prince Charles (later King Charles I), and organist at Westminster Abbey. He died at age 41 in Canterbury of apoplexy, and a monument to him was built in Canterbury Cathedral. A suspicion immediately arose that Gibbons had died of the plague, which was rife in England that year. Two physicians who had been present at his death were ordered to make a report, and performed an autopsy, the account of which survives in The National Archives:
