What is a Chord Calculator?

A Chord Calculator is an interactive tool designed to help musicians identify the notes and intervals that make up different chords. Instead of manually figuring out the notes for a specific chord, you can simply select the root note and chord type, and the calculator instantly reveals the chord name, its notes, and the intervals between them.

This tool is perfect for:

Beginner musicians learning chords and music theory.
Songwriters experimenting with new chord combinations.
Teachers creating educational content.
Composers needing quick references for chord structures.

How to Use the Chord Calculator

Using the Chord Calculator is straightforward and requires no prior technical knowledge. Here’s a step-by-step guide:

Step 1: Select the Root Note

The root note is the base or starting note of your chord. The tool offers a dropdown menu with all 12 musical notes:

Natural notes: C, D, E, F, G, A, B
Sharps (#): C#, D#, F#, G#, A#

Choose the note that will serve as the foundation for your chord.

Step 2: Choose the Chord Type

The chord type defines the quality and character of the chord. The tool provides several popular chord types:

Major
Minor
Diminished
Augmented
Major 7th
Minor 7th
Dominant 7th
Suspended 2nd (sus2)
Suspended 4th (sus4)

Select the chord type you want to calculate.

Step 3: Calculate the Chord

Click the Calculate button. The tool instantly displays:

Chord Name — Combining root note and chord type (e.g., C Major)
Notes — The specific notes that make up the chord (e.g., C – E – G)
Intervals — The musical intervals between the notes (e.g., Root – Major 3rd – Perfect 5th)

If you want to start over or try a new chord, simply click the Reset button.

Example: Calculating a C Major 7th Chord

Let’s walk through an example using the Chord Calculator:

Select C as the root note.
Choose Major 7th as the chord type.
Press Calculate.

Result:

Chord Name: C Major 7th
Notes: C – E – G – B
Intervals: Root – Major 3rd – Perfect 5th – Major 7th

This tells you that a C Major 7th chord consists of four notes: C (root), E (major third), G (perfect fifth), and B (major seventh). Now you know exactly what to play on your instrument.
