ancient Greek music

Here's one for you tuning historians...I got a call to possibly get
involved in a play here in Denver about the Trojan wars. They're just
getting ready to start working on the music, and I am wondering what
instruments would have been in use at that time, and what the tunings
might have been. Also, where would one get said instruments, if
anywhere? The play is called Tantalus, and it is a 15 hour show, believe
it or not...a complete show runs 3 consecutive days, or 2 weekend
days...whacked, but should be interesting. Any help is appreciated,
please post me privately (unless an answer would be of general tuning
list interest, which it well might)...thanks...Hstick
