A guitar is a musical instrument that has six strings. Imagine the strings are like the strings on a fishing rod but are meant for making beautiful sounds instead of catching fish!
To play the guitar, a musician uses one hand to pick at the strings. Picking is like strumming your hair or the soft fur of a cat; it makes a sound when you touch the strings! They can use their fingers or a special tool called a pick.
With their other hand, they press down the strings on the guitar neck, which is the long part of the guitar. Pressing the strings makes different sounds, like when you press harder or softer on a balloon. The stronger the press, the different the notes will sound!
So, when a musician plays the guitar, they are using both hands to make music that can sound happy, sad, or exciting. It's like creating a song from their heart!
