1. What is a Guitar Chord?

A guitar chord is a combination of musical notes played simultaneously. Chords are built from a root note plus specific intervals that determine the chord's quality (major, minor, etc.).

2. How Does the Calculator Work?

The calculator uses the chord formula:

Where:

• \( root \) — The fundamental note of the chord
• \( intervals \) — Specific distances from the root note that define the chord type

Example: A major chord consists of the root, major third (4 semitones above root), and perfect fifth (7 semitones above root).

3. Importance of Chord Theory

Details: Understanding chord construction helps guitarists with songwriting, improvisation, and music theory comprehension.

4. Using the Calculator

Tips: Select a root note and chord type to see the component notes. This helps in understanding chord construction and finding alternative voicings.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between major and minor chords?
A: Major chords use a major third interval (4 semitones) while minor chords use a minor third (3 semitones).

Q2: How do 7th chords differ from regular chords?
A: 7th chords add a seventh interval (10 semitones for dominant 7th, 11 for major 7th) to the basic triad.

Q3: Why are some notes called 'flat' in intervals?
A: Flat intervals are one semitone lower than their natural counterparts (e.g., b3 is 3 semitones, vs. natural 3 which is 4 semitones).

Q4: Can I use this for other instruments?
A: Yes, chord theory applies to all instruments, though fingerings will differ.

Q5: How do I play these chords on guitar?
A: The notes shown can be played in various positions on the fretboard. Consult chord diagrams for common fingerings.
