Guitar tabs are an easy solution for you if you have no idea of how to read sheet music but are constantly bugged by the notion that you want to be a guitarist. Guitar tabs are easy to learn and allow you to begin playing songs right away, even if you are not familiar with them. Once you have bought your first guitar, it is time to begin looking for easy guitar tab versions of some songs to find out what it feels like to be a guitar player. Which songs you need tabs for depends on how you see yourself as a musician.
Do you want to play your favorite songs chiefly for your own amusement or do you want to aim your repertoire at a potential audience? Let us look at your audience for a minute. The most popular songs in the world are all from years gone by. If you sit a bunch of people aged between ten and fifty down and play songs at them you will find some universal favorites, and they will all be old songs. If you want to please a random audience, your ultimate goal should be to have about one hundred popular songs ranging from the 1940’s to the present, but you could probably narrow the range to just include songs going back to the sixties.
