I thought it was really interesting hearing examples of the music in the bible. The lyre especially is really fascinating to me. As a guitar player, amongst other things, the lute made more sense to me. But, it was really cool seeing the lyre because of the lack of frets. The music was so complex with just the ability to play the arpeggio with what sounded like a seventh. It would be interesting to know if they can change the tuning to have different arpeggios and chromatics or if all of them are just set?
