The three six-part masses by John Taverner are towering monuments of English pre-Reformation church music. Probably written in the mid-1520s shortly after Taverner had become choirmaster of Cardinal College, Thomas Wolsey’s new collegiate foundation at Oxford, they culminate the florid polyphonic style that had been developing in England since the mid-15^th century, at the same time strengthening it with a new sense of sinew and logic derived from close motivic argument and purposeful gradation of musical tension. Gloria tibi trinitas may have been intended for Cardinal College, which gave the Holy Trinity pride of place in its dedication.
