Charlie Hunter is a musician who plays the guitar. But he doesn't just play any normal guitar - he plays a special kind of guitar that has extra strings on it. Most guitars have six strings, but Charlie's guitar has eight strings.
Now, when you play a guitar you usually use your hands to pluck or strum the strings. But Charlie has a secret superpower - he can also use his feet to play another instrument at the same time! It's called a bass. The bass makes really low notes and helps keep the music sounding nice and steady.
So when Charlie plays his guitar and bass at the same time, it kind of sounds like there's a whole band playing all by himself! He can make lots of different sounds and styles of music, like jazz, blues, and funk.
People love to watch Charlie play because it's really impressive and fun. Plus, he makes lots of people happy with his music!
