This tune is played around 130 BPM. That's pretty fast. We have the suggested starting tempo set to 80 BPM. If you need to, set it even slower or pause it and play and learn at your own pace.
If you try any Scruggs style licks that incorporate rolls you may need to slow the overall tempo down so you can use them in the song. Rolls use 16th notes, and the faster we go in the song is a series of 1/8th notes. Basically, you'll half to play twice as fast when playing rolls as you do in the basic melody, so be prepared!
