I am learning how to play simple man which is one of the beginner songs. I am confused by the bpm that appears in the tabs. I am using a metronome to count the beats. It shows 61 bmp in the tabs which is a slow tempo and that is the speed the teacher is playing while showing the strumming. But when it is time to perform the song, it seems a lot faster than 61 bmps, but that is the speed that shows in the tabs.What am I doing wrong?
