What Guitar Chord Chart does and how it behaves

Guitar Chord Chart displays fretboard diagrams for major, minor, 7th, and extended guitar chords. Select a root note and chord quality, then read the marked string and fret positions as a playable shape. Open or muted string symbols, when present, are part of the fingering rather than optional decoration. The main surprise is that a chord name does not determine one unique shape: the displayed diagram represents a particular voicing, while other positions, inversions, and fingerings may produce the same named chord.

How the result is produced

1

Choose the chord

Use the available chord choices to combine a root note with a quality such as major, minor, 7th, or an extended form. The resulting chart identifies a fretboard shape for that named harmony. Similar names are not interchangeable: C, Cm, C7, and an extended C chord contain different note combinations and therefore require different diagrams.

2

Read the diagram

Each marked intersection represents a string held at a particular fret. A marker beyond the nut means the string is fretted; an open-string marker means it sounds without fretting. Where muted strings are identified, do not sound them. If finger numbers appear, they suggest which fretting-hand fingers to use; otherwise the chart specifies positions but leaves finger assignment to the player.

Good uses

  • Checking the fret positions for an unfamiliar chord encountered in a song or lesson.
  • Comparing major, minor, 7th, and extended shapes built on the same root note.
  • Keeping a chord diagram visible while practicing transitions between shapes.

Limits and checks

  • Treat each diagram as one voicing, not a complete list of every valid way to play the chord.
  • Confirm which strings are open, fretted, or muted; sounding an excluded string can change the harmony.
  • Chord shapes depend on tuning. A familiar shape may produce different notes when the guitar is not in the tuning expected by the chart.

Common questions

Does the chart show every valid fingering for a chord?

No. Most guitar chords can be placed in several fretboard positions and may use different inversions, duplicated notes, or omitted notes. A displayed chart gives a usable shape associated with the selected chord name. It should not be read as proof that other shapes are incorrect.

Why does the chord sound wrong when my fingers match the dots?

Check the strings that should remain open or muted, along with the guitar's tuning. Accidentally sounding a muted string, silencing an intended open string, or using an alternate tuning changes the resulting notes. Fret each marked note cleanly and compare the diagram's string order carefully.
