Chord Finder Calculator
A chord finder is a valuable tool for musicians, songwriters, and music enthusiasts that helps identify and construct musical chords.
A chord finder allows users to input notes or select them on a virtual instrument, and then it determines the corresponding chord name.
When you're playing a piano and press the keys C, E, and G simultaneously. A chord finder would recognize this combination as a C major triad. Chord Finder Chart

Chord Finder Formula
The chord finder formula is based on the intervals between notes in a scale. For major and minor chords, the formula uses the 1st, 3rd, and 5th degrees of the respective scale. Here’s a breakdown:
Major chord formula: 1 – 3 – 5
Minor chord formula: 1 – ♭3 – 5
Diminished chord formula: 1 – ♭3 – ♭5
Augmented chord formula: 1 – 3 – #5
Let’s take the key of D as an example:
- D major scale: D – E – F# – G – A – B – C#
- D major chord: D (1st) – F# (3rd) – A (5th)
- D minor chord: D (1st) – F (♭3rd) – A (5th)
How do I find Chord For my Song?
To find chords for your song, start by identifying the key and melody. Here’s a step-by-step example:
Let’s say your song is in the key of G major, and your melody starts with the notes G, B, D.
These notes form a G major chord (G-B-D).
For the next part of your melody, you might use A, C, E.
These notes form an A minor chord (A-C-E), which is the ii chord in G major.
Continue this process, matching melody notes to chords that fit within the key of G major.
Remember, not every melody note needs its own chord. Experiment with different chord progressions to find what sounds best with your melody.
