Matt grows the best vegetables in the village. He grows fruit too – big, sweet apples and oranges. And what else? Well, the biggest and the prettiest flowers.

Things grow in Matt’s garden all through the year. He cuts some flowers for his sitting room table; and of course , he eats some fruit and vegetables. But he sells everything else in the market. Matt is not a poor man.

He knows a few other gardens; but he does not have any friends. You might ask, “What is that?” Why doesn’t he have friends. I will tell you. People do not understand him. And they do not understand his garden. “Why not?” You will ask. “It is a very good garden, isn’t it?” It is a wonderful garden. Matt plants things in spring, summer, autumn and winter. After that he does very little work. He sits in the garden with his small radio. And everything grows.

People ask, “How does Matt grow these wonderful things? He waters the plants sometimes, but he doesn’t do anything else. He just sits under an orange tree with his radio. He listens to music nearly all day!” and that is all quite true. People cannot understand it, and so they don’t like it very much.

Matt likes music. But what about the garden? Who does the work? I will tell you another true thing: the music does the work. All plants love music; and Matt knows that.

Do you want big vegetables and the loveliest flowers? Well, just give your plants a lot of music.
