Music Theory for Guitar: What is Relative Major & Minor?

In this super quick music theory lesson, we’re diving into the concept of relative key signatures. Understanding relative keys can significantly simplify guitar playing, improvisation, and songwriting, even for beginners. Let’s jump right in!

What is a Relative Key Signature?

A relative key signature is essentially two key signatures—one major, one minor—that share exactly the same notes, including any sharps or flats. The only difference between them is the tonal center or the starting note of the scale.

To illustrate, let’s consider G major and E minor:

  • G Major: G, A, B, C, D, E, F#, G
  • E Minor: E, F#, G, A, B, C, D, E

Notice how both keys share identical notes, but the difference lies in which note the scale starts and resolves upon.

How to Find the Relative Minor from a Major Key

Finding the relative minor key from a major key is simple:

  • Identify the sixth scale degree of the major scale. This note is your relative minor.

Example: In G major, the notes are G (1), A (2), B (3), C (4), D (5), E (6), F# (7), and G (8). The sixth note is E, making E minor the relative minor key.

How to Find the Relative Major from a Minor Key

Similarly, to find the relative major from a minor key:

  • Identify the third scale degree of the minor scale. This note is your relative major.

Example: In E minor, the notes are E (1), F# (2), G (3), A (4), B (5), C (6), D (7), and E (8). The third note is G, which makes G major the relative major key.

Why Learning Relative Keys is Beneficial

When you learn a single scale, you’re effectively learning two scales because every major scale has a relative minor counterpart and vice versa. This greatly enhances your fretboard understanding and playing versatility.

Practical Benefits:

  • Improved fretboard navigation: Quickly move between major and minor tonalities.
  • Easier improvisation: Seamlessly switch between scales during solos.
  • Efficient songwriting: Create interesting harmonic progressions using both tonalities.

FAQ – Quick Tips About Relative Major & Minor

  • What exactly is a relative key signature?
    A relative key signature is two keys—one major and one minor—that contain the same exact notes but start and resolve differently.
  • How do I find a relative minor key?
    Locate the sixth note of the major scale; that note becomes your relative minor.
  • How do I find a relative major key?
    Locate the third note of the minor scale; that note becomes your relative major.
  • Do relative keys have the same chords?
    Yes, relative keys share the exact same chords but differ in how these chords are emphasized or resolved.
  • Can beginners easily learn relative keys?
    Absolutely! This concept is straightforward and helps beginners quickly expand their musical knowledge.

Understanding and using relative major and minor keys is a simple yet powerful skill that every guitarist should master. It enhances your playing, songwriting, and improvisational abilities, making you a more versatile and confident musician.
