Musical theory is like learning to play with building blocks. You remember those blocks that come in different shapes and sizes, and you can stack them up to make all sorts of cool things? Just like that, musical theory is a bunch of rules and tricks that help musicians build songs and sounds that make people happy.
The very first thing we need to learn about is pitch. Pitch means how high or low a note sounds. Imagine standing at the bottom of a big slide. You start at the bottom and then climb as high as you can to the top. The top is like a high pitch, and the bottom is like a low pitch.
Next, we need to talk about rhythm. Rhythm is all about timing and how long each note lasts. Just like how you might count, "1, 2, 3, 4" while jumping rope or clapping your hands, musicians count different rhythms to make their songs sound fun and interesting.
As we start to learn more about music theory, we'll learn about chords, which are like blocks that you can stack together to make bigger structures. And we'll learn about scales, which are groups of notes that sound good together and form the foundation of almost all Western music.
By learning these basic building blocks of music theory, musicians can create their own songs and tell all sorts of wonderful stories through the language of music.
