music theory

Music theory is the study of how music works. It's the science of understanding and creating music - like the way mathematicians understand how numbers work and how to use them. Music theory looks at the different sounds and notes that make up a song and how they work together to make music we like to listen to. Music theory helps us understand why certain notes, beats and rhythms sound good together, and how to make music that is pleasing to the ear. It's like learning a language: by understanding the structure and rules of music, you can use them to create songs.
