What is true of it
E is E, G♯ and B — 1, 3 and 5 counted from E.
On an instrument that cannot reach all 3, the 5 goes first, in that order.
The easiest of the 5 fingerings below is 022100: 3 fingers, held at the 1st fret.
3 of them use open strings, which is what makes a shape quiet to change to.
Where its notes are on the neck
