Editing Cadence (section)

=== English cadence ===
Another "clash cadence", the [[English cadence]], is a [[contrapuntal]] pattern particular to the authentic or perfect cadence. It features the [[Blue note|blue seventh]] against the [[dominant chord]],<ref>[[Peter van der Merwe (musicologist)|van der Merwe, Peter]] (2005). ''Roots of the Classical: The Popular Origins of Western Music'', p. 492. {{ISBN|0-19-816647-8}}.</ref> which in the [[Key (music)|key]] of C would be '''B{{music|flat}}''' and G–'''B{{music|natural}}'''–D. Popular with English composers of the [[High Renaissance]] and [[English Restoration|Restoration]] periods in the 16th and 17th centuries, the English cadence is described as sounding archaic<ref>Carver, Anthony (1988). ''The Development of Sacred Polychoral Music to the Time of Schütz'', p. 136. {{ISBN|0-521-30398-2}}. If the clash cadence is already "archaic, [and/or] mannered" in the music of [[Heinrich Schütz]] (1585-1672) it must surely be so now.</ref> or old-fashioned.<ref>[[Rebecca Herissone|Herissone, Rebecca]] (2001). ''Music Theory in Seventeenth-Century England'', p. 170. {{ISBN|0-19-816700-8}}.</ref> It was first given its name in the 20th century.

The hallmark of this device is the [[Consonance and dissonance|dissonant]] [[augmented octave]] (compound [[augmented unison]]) produced by a [[false relation]] between the split seventh [[Degree (music)|scale degree]], as shown below in an excerpt from ''[[O sacrum convivium]]'' by [[Thomas Tallis]]. The [[courtesy accidental]] on the tenor's G{{music|natural}} is editorial.
