Divide the participants into four groups. Every participant draws from a hat/bag a piece of paper on which is written the name of an animal (e.g. dog, cat, chicken, cow, sheep, frog, etc.): in each group’s hat/bag the animal names appear only once and one paper will say “conductor”. The groups have five minutes to decide on a song they will perform and to practise it, but they can only use the sounds of the animals that they have drawn. After that the concert begins and the groups perform one by one.
