The idea is to help guitarists to learn new songs faster. By following the chords before us as the song plays. Is this a new learning technique? Maybe, but for me, always looking for ways to play new songs, I came up with this new video idea, and it works.
So if you are new guitarist, try it, it's easy and fun and if you practice one to two hours per day, in a few years you will be a good guitarist. That's the thing, practice, practice and practice. The more you practice, the better you will be.
To find the songs available. You only have to navigate the left menu, I put the links in chronological order. By clicking "50 'to 60' C & L" for example, you can see the songs from 1950 to 1960 and and so on.
