So, imagine you are playing with your favorite toy blocks. You have different shapes and colors, right? Now, let's say you have a blue block, a red block, and a green block. When you put them together, you create something new! You have made a pattern of colors.
Now, let's relate that to music. In music, we have different "blocks" that we put together to make a song. One of those blocks is called a "part." A part is like a pattern of notes that repeats throughout the song.
Just like you used your different toy blocks to create a colorful pattern, musicians use different parts to create a song. Each part can be played by a different instrument or sung by a different voice. For example, in a band, the drummer may be playing one part while the guitarist plays a different part.
So when you listen to music, you can try to listen for the different parts and hear how they all work together to create the song you enjoy!
