Ok, here's the deal. It's not the actual guitar part. The upper treble cleff is the melody of the vocals. The bottom treble and bass cleffs are the actual piano parts. Those kind of books aren't good for the real part. A lot of it is kind of made up. But if you play the upper treble cleff on guitar, it will just be what Roger is singing. Got it? My sister works at a sheet music store so if you have any more questions just ask me. And welcome to the site!
