When the king got older he could not dance and so he became less interested in ballet. So Lully became more interested in composing operas. He earned a lot of money from this, because there was an arrangement with the king that Lully would have complete control of any music that was published in France. Lully had become a very powerful man, and many other musicians did not like this. There were a lot of arguments, especially when Lully did not allow music in puppet shows.
