MUIC & ACOUTIC – MUIC THEORY & HARMONY CALCULATOR
Relative Key
A precise tool.
What is the Relative Key & How does it work?
In music theory, the concept of relative keys is fundamental to understanding how different scales relate to each other. The relative major and minor keys share the same key signature, meaning they have the same number of sharps or flats in their respective scales.
For example, if a piece is in the key of G Major (with one sharp), its relative minor key would be E Minor. Conversely, if a piece is in the key of A Minor (with three sharps), its relative major key would be C# Major.
relative_minor = root_major – 3
root_major = the root note of the major key
relative_minor = the root note of the relative minor key
relative_minor = the root note of the relative minor key

Frequently Asked Questions
What is a relative key in music?
A relative key is a key that shares the same key signature as another key, meaning it has the same number of sharps or flats. For example, G Major and E Minor are relative keys.
How do I find the relative minor of a major key?
To find the relative minor of a major key, count down three half steps from the major key’s tonic note. For instance, the relative minor of G Major is E Minor.
Can you explain how relative keys share the same key signature?
Yes, relative keys have identical key signatures because they are built on the same set of notes but start from different tonics. This means they contain the same number of sharps or flats.
What is the relationship between C# Major and A Minor?
C# Major and A Minor are relative keys, sharing the same key signature with three sharps. They have the same notes but start from different tonics.
How do I use this calculator to find a relative key?
Enter the name of your key into the calculator, and it will display its relative major or minor key based on their shared key signature.
Is there a difference between parallel keys and relative keys?
Yes, parallel keys share the same tonic but have different modes (major vs. minor), while relative keys share the same key signature but start from different tonics.
Can this calculator help with transposing music?
While this calculator doesn’t directly transpose music, understanding relative keys can help in transposing pieces by maintaining the same key signature.
