i read 'goedel, escher, bach' more than ten years ago - a fascinating book, but not an easy one. with regard to the composition techniques, hofstaedter - for the most part and as far as i remember - refers to bach's 'art of fugue'. in fact, 'goedel, escher, bach' inspired me to get a recording of this fascinating piece (kenneth gilbert on DG/archiv). however, this might not be the kind of baroque music you are looking for. not very easy to listen to, but still enjoyable (harpsicord, though).
for a better understanding of hofstaedter's work it might also help, if you read up a little on canons, fugues, contrapunctus etc. (i have to admit, i only have a very basic understanding of these topics).
