How to play F13
Root, third and seventh. The third and seventh, the guide tones, are what make the chord major, minor or dominant, so the fifth can go: it says nothing the symbol needs.
Three notes means a spare string, which is the real point. Put a tension on it.
F13 has 3 of them, on strings 6-4-3-2 and strings 5-3-2-1, from open position up to the 13th — all in one inversion, so the bass note never moves. The one to learn first is the F shape at the nut.
Start with x-8-7-8-10-10 — no barre. None of the shapes for F13 uses an open string, so every one of them is movable; the lowest sits at the 1st fret. 6 of the 7 need a barre. Together they cover the neck from the 1st fret to the 15th.
