||John Tavernerís Mean Mass is so called because the top voice is for boy altos (means) rather than trebles. Probably one of Tavernerís late works, it shows a mastery of imitative counterpoint and a sense of economy and symmetry which were to influence William Byrd when he composed his own Masses half a century later. This reprint includes some small corrections and revisions. More importantly, it also includes two complete copies of the edition, one at the original written pitch and one transposed up a tone. For five voices: ATTBarB. ix + 46 pages. ISMN 979-0-57039-079-3.
