Guitar notation has a dirty secret: it uses numbers for four different things and rarely tells you which is which. Frets, fingers, strings, and tab positions — all integers, all different systems. No wonder charts feel like tax forms at first. Five minutes of untangling and they never confuse you again.
Frets count from the headstock: fret 1 is closest to the tuning pegs, and numbers climb toward the body. 'Play the 5th fret' means press between the 4th and 5th fret wires. The dots on your neck are mile markers — 3, 5, 7, 9, and double dots at 12 (where everything starts over an octave up).

▲ WATCH OUT
String 1 is the SKINNY one
Tab is six horizontal lines (top line = the SKINNY high E — floor-up again) with numbers ON the lines. Those numbers are FRETS, never fingers: an 8 on the second line means 'B string, 8th fret' — with whichever finger makes sense. A 0 means open string. This is the single most useful disambiguation in guitar notation: diagram numbers = fingers, tab numbers = frets.
The decoder ring:
- 1Chord diagram: grid = strings and frets, dots = where to press, numbers = FINGERS (1–4).
- 2Tab: six lines = strings (thin E on top), numbers = FRETS, 0 = open.
- 3'3rd fret' = a place on the neck. '3rd finger' = your ring finger. '3rd string' = the G.
- 4When any chart confuses you, ask: is this number a place (fret), a tool (finger), or a lane (string)?
Place, tool, or lane. Every number in guitar notation is one of the three. Run the question a few times and the decoding goes automatic. Tax forms to street signs, one afternoon. Precision is just clarity you practiced.

Question 1 of 3
In a chord diagram, the small numbers on the dots are…
The cheat sheet
- Four systems: frets (places), fingers (tools, 1–4), strings (lanes, thin=1), tab (frets on lines).
- Chord-diagram numbers = FINGERS; tab numbers = FRETS. Never the reverse.
- String 1 is the skinny high E — counting starts at the floor.
- Confused by a number? Ask: place, tool, or lane?
Common questions
What do X and O above a chord diagram mean?
O = play that string open (unfretted); X = don't play it at all (skip or mute it). They sit above the grid, one per string. The C chord's X on the low E is why strumming all six sounds muddy.
Why does tab put the HIGH string on top?
It mirrors the player's view looking down at the guitar in their lap — the thin string really is 'on top' from where you sit. Reading it as a bird's-eye view of your own fretboard makes it click.
Do tabs tell me the rhythm?
Basic internet tab, barely — numbers are spaced roughly in time but you're expected to know the song. That's why tabs work best paired with the recording (and why we teach counting separately).
