Master Guitar Chord Theory

Chord Construction

Chords consist of three or more notes played together. Major triads use the root, major third, and perfect fifth. Minor triads use the root, minor third, and perfect fifth. Use the identifier to see these formulas in real-time.

Interval Relationships

Intervals measure the distance between notes. The "root" note defines the chord name. The "third" determines the quality (major or minor). The "seventh" adds harmonic complexity often found in jazz and blues music.

Guitar Voicings

Voicing refers to the arrangement of notes on the strings. The same chord appears in multiple positions on the neck. Our tool identifies inversions and slash chords where the lowest note differs from the root.

Frequently Asked Questions

How do I find a chord name?
Click the frets on the virtual board to match your guitar shape. The tool calculates the notes and names the chord instantly.
What does the "X" and "O" mean?
"O" represents an open string. "X" means the string is muted or not played. Use the toggles on the left of the board to change string status.
Does this work for alternative tunings?
This version uses Standard Tuning (E-A-D-G-B-E). Support for Drop D and Open tunings is planned for future updates.
