I have a friend who is a very well respected 'early' musician - plays in various groups and consorts. He is also working this season at the Shakespeare Globe and I went to see the show last week (Romeo & Juliet). He was playing this blooming huge lute type thing which, I understand, is called a theorbo - has two sets of pegs on a neck which must be five feet long. I didn't get a chance to ask him about it after the show cos we both had to go separate ways and the stuff I've found on the net looks very academic. Can anyone tell me about this thing in simple, layman's terms?
