The program Fender's Riffstation, which can scan any audio file and then help you learn how to play it on your guitar, is now shipping free, from $ 35 that until recently.
The app has the ability to scan your favorite songs and then show you the strings used in them, as well as how to place your fingers on the fretboard. It does not always have perfect results, but it's a great way to start learning on your guitar any song you like.
And if you have just started learning guitar, you will find that there is much more to it tricks to help you. You can break the songs into smaller pieces, called riffs, and play them in slow repetitions until you learn how to play them properly. You can even isolate the rhythm from the guitar, allowing you to hear only one or the other.
The application was costly up to date with 35 US dollars, but today you can download completely free from here.
It runs in the Windows and MacOS operating systems.
