Sing a well known song such as “Happy Birthday”. Sing the song at normal speed. How does that make you feel? Now sing the song very, very quickly (loads of giggles!). How does that make you feel? Now sing Happy Birthday like a funeral drone. How does that make you feel? Try this with several other well known songs. Try with poetry as well.
The speed of the music in many ways shapes the emotion and the feelings of the piece.
