I was thinking about what song to go with when it comes to explaining guitar tabs. And I ended up with a song called The Entertainer. This song is not an easy song to learn for a beginner. But we will only use the first part of the song (first 10 seconds to be exact) and actually once you get going it's not that hard. It's something for you to work on and maybe someday you will play the whole thing. Now the song The Entertainer is an old piano rag by Scott Joplin. It's an famous song, you probably have heard it already. A version of the song appears in the video game Gran Turismo 5 as the background music for the "GT Auto" menu screen. In the United States, "The Entertainer" is also commonly played by ice cream trucks, in order to attract attention.
I will show you a video of Chet Atkins performing the song The Entertainer way back in 1975. This video will show you how to place you're fingers. That's a thing when it comes to guitar tabs. They don't show you how to place you're fingers the best way on the fretboard. That's something for you to figure out. But the rule of thumb is to place the fingers so that you can move around on the fretboard with ease while playing. What feels right is usually the right way to play the song.
