I'm Reno McCormick and we're going to tell you about tuning string instruments today. This is a mandolin that has eight strings, four sets of two. So the highest string is E, you want to tune both. We tune one to E, and then we try to match the other one to it. That sounds good to me. Oh that's bad! So this is our A, we have two A's. And if you play violin, it's tuned exactly the same. In the turn of the twentieth century, there were quite a few mandolin orchestras. I think they refer violin orchestra drop outs, which I would have been part of. And they have mando cello's and octave mandolins. Just like the violin family. And when you're playing mandolin, it's so much easier than the violin. All we have to, especially if you're a guitar player. We use a pick, just like a guitar player, and we use the violin fingerings. It's real easy to tune a mandolin, which is backwards of the four base strings of a guitar. G, D, A, E instead of E, A, D, G. G, D, A, E. On a guitar, the fifth fret gives you the next string. On a mandolin, seventh fret gives you the next string. So we have G, A, B, C, D, which is our next string. For D string, we go to the seventh and it gives us our next string which is A. And with the E, same thing, seventh fret of the A gives us E. And we can check our harmonics on this. So let's check. The twelfth fret of the E string will give us an E, and the seventh fret of the A string will also give us an E. This is only doing harmonics. They're hard to get on a mandolin. So there you have the mandolin.
