"Dr Tye was a peevish and humoursome man, especially in his latter dayes, and sometimes playing on ye Organ in ye chapel of qu. Elizabeth wh. contained much musick, but little of delight to the ear, she would send ye verger to tell him yt he play'd out of Tune: whereupon he sent word yt her ears were out of Tune"
Can anybody tell me what is meant by "yt"?
ETA: Problem solved, thanks all.
