Played open, the strings sound F#-B-E-A-C#-F# – from F#2 at the bottom to F#4 at the top, a span of 2 octaves. Step by step across the neck the intervals are a fourth, a fourth, a fourth, a major third, a fourth, and that is what decides how chord shapes fall under the hand.

The strings are pulled above their normal pitch, so a lighter set reduces the risk of breaking a string or over-loading the neck.

History

Where the Plus 2 (F#) tuning comes from

Raising every string a whole step puts a lot of extra tension on a guitar, so this tuning has always been a niche choice rather than a tradition. It is sometimes used with light-gauge strings to fit a high vocal key with open chord shapes, or on short-scale guitars. There is no known inventor or historical school behind it.
