1. What is Chord Identification?

Chord identification determines the type of chord based on the intervals between its constituent notes. This calculator identifies common chord types like major, minor, and seventh chords from the input notes.

2. How Does the Calculator Work?

The calculator works by:

1. Converting note names to pitch numbers
2. Calculating intervals between notes
3. Matching interval patterns to known chord types

3. Importance of Chord Identification

Details: Identifying chords is fundamental to music theory, composition, and performance. It helps musicians understand harmonic progressions and create more sophisticated musical arrangements.

4. Using the Calculator

Tips: Enter notes separated by commas (e.g., "C,E,G"). The calculator recognizes common note names including sharps and flats. For best results, enter at least 3 notes to identify more complex chords.

5. Frequently Asked Questions (FAQ)

Q1: What note naming conventions does this support?
A: The calculator recognizes standard note names (A-G) with sharps (#) or flats (b).

Q2: What chord types can it identify?
A: Currently recognizes major, minor, diminished, augmented triads, and common seventh chords.

Q3: Does it account for inversions?
A: Yes, the calculator sorts notes before identifying intervals, so inversions are handled correctly.

Q4: What about extended chords (9th, 11th, etc.)?
A: Currently focuses on basic triads and seventh chords. Extended chords may return "Unknown".

Q5: Can I input MIDI note numbers instead?
A: This version only accepts note names, but future versions may support MIDI input.
