The main riff (verse riff) is compromised of two different guitar parts.
Both parts are fairly easy to play. Both guitar parts are repetitive and are composed of single-note lines that would be a good challenge for progressing beginners.
Try switching out guitar 1 and guitar 2 when playing with a buddy. It’s a lot of fun and will help you learn to play well with others.
Here’s what both guitars sound like together:
Guitar 1
Guitar 2
