The Megatar is a big instrument that is kind of like a guitar and a bass put together. It has a lot of strings, usually 10 or 12, that all have different notes. When you play it, you use both hands to tap on the strings and make different sounds. Some people like to use it to play really cool and funky music. It's a big instrument, but if you practice and learn how to play it well, you can make some really amazing music!
