Locrian Mode: The Music Modes

The Locrian mode is one of the seven main music modes in Western music and is characterized by its unique sound and distinct pattern of whole and half-steps. While it is the least used of all the modes, it has a unique and eerie quality that sets it apart and makes it an important mode for musicians to understand.

Locrian Mode Formula

The Locrian mode is defined by the pattern of whole and half-steps, starting from the seventh note of a major scale. The formula follows these intervals: H – W – W – H – W – W – W (W = “whole step” or “tone” and H = “half step” or “semitone”).

The Locrian mode has a dark and unstable feel, making it a popular choice for experimental and avant-garde music.

Dissonant Fifth Interval

One of the key features of the Locrian mode is its dissonant fifth interval, which creates a sense of instability and tension. This is in contrast to the Ionian mode, which has a stable and consonant fifth interval. This makes the Locrian mode particularly well-suited to music genres that emphasize tension or conflict, such as avant-garde classical music, metal, or film scores. Because of the unnatural, dissonant sound that the Locrian mode provides, this mode is the least used of all.

Key Signatures & Example Songs

In terms of key signatures, the Locrian mode is associated with diminished triads, which are composed of two minor thirds. Diminished triads have a tense and unstable sound, adding to the overall eerie and experimental feel of the Locrian mode.
