A guitar is an instrument that makes music! It has six strings that are like thin ropes. When someone wants to play the guitar, they use one hand to pick the strings. This is like how you might strum a candy cane, but with fingers instead!
With their other hand, the musician presses down on the strings on the neck of the guitar, which is the long part where the strings are. Pressing the strings in different places makes different sounds, like how you can make different notes when you play simple games. So, one hand picks or strums the strings, and the other hand helps change the sound by pressing on them. Together, they make beautiful music!
