Playing a Loog is the same as playing any guitar, only simpler and with less things to remember.
We use the first 3 strings you would find on any guitar, with the same tuning: G B E, from low to high.
In that way, what you learn on a Loog can later be applied on a 6-string guitar.
You can even read chord diagrams from books or from the internet and use them to play your favorite songs on a Loog Guitar: Simply focus on the first 3 strings and ignore the other ones.
And to make things even easier we have a series of video-lessons designed to get you playing in just a few minutes. See it here.
