I came across this memorable lesson when browsing old articles in Education Guardian. You can read the whole article here.

One lesson I remember was during my A-levels. We were working on the Comedy of Errors - the soliloquy that starts "I to the world am like a drop of water" - but instead of sitting in class, we had to memorise a line, then run around the hall each saying our own line in order. Because we were running around, we had to shout our lines, and really listen to the lines being said. It made you concentrate on the words, and the theatricality of them, instead of just sitting analysing text.

How would this work with the choruses in Agamemnon? Just a thought.
