Advantage of a Bad Ear

Can any of your readers supply the name of the man of mark in English history, who says "he encouraged in himself a bad ear, because it enabled him to enjoy music he would not have enjoyed without?" I have looked through the lives of Lord Herbert of Cherbury, Hampden, Hobbes, Andrew Marvell, and Fletcher of Saltoun, without finding it; though it is possible it may be in some of these after all. The list given will point to the kind of personage in question.
