Invention (musical composition)

An invention is like playing a game. It's a musical game where you make up new notes as you go along. It's like building something out of blocks but with music. You start with a little idea, like playing a few notes on the piano, then you keep adding more and more until you have a whole song! Just like building with blocks, you can change and rearrange the notes until it sounds just the way you like it. And just like playing a game, it's really fun!
