In classical music there is a special term for music that tells or story or paints a picture. It is called ‘Programme Music’.
Can you use your instrument to create some Programme Music? You could think of a picture and create sounds that remind you of that picture. You could think about a scene, like a stormy day ☔ or the sun setting over the sea 🌞. They don’t all have to be nice sounds! Or how about a fairy story – you could create different sounds for the happy, sad, dangerous and exciting parts of the story.
