Overview. The Locrian mode is the only modern diatonic mode in which the tonic triad is a diminished chord, which is considered dissonant. This is because the interval between the root and fifth of the chord is a diminished fifth. For example, the tonic triad of B Locrian is made from the notes B, D, F.

The diminished scale is used to solo over diminished 7 (Dim7) chords.

When first exploring diminished scales on guitar, it is easy to confuse these two scales.

Why is Locrian mode not used?

One of the issues with the Locrian mode is simply how unstable and unreliable it is as scale. Because the idea of using a diminished fifth and a minor second promotes such an unclear tonic, it’ll prove incredibly difficult to make your use of the Locrian mode actually sound ‘final’ when it reaches its tonic.

Why is Locrian rarely used?

Because it’s hard to get the hang of. In western practice, chords are built in thirds, and the simplest kind of chord is a triad (consisting of a root, a third, and a fifth). In the Locrian mode, the fifth above the tonic note is a diminished fifth, so its presence causes the tonic chord to sound restless and unstable.

In other words, if you form a diminished chord on the fretboard of the guitar, keyboard or any instrument and then move that same chord three semitones up or down, the chord will remain the same! This is very convenient, because if we want to play, for example, A°, we can play C° (since it is the same chord!).

How do you substitute diminished chords?

The diminished seventh chord is often used in place of a dominant 7th chord. In the key of A Major the V chord, E dominant 7th (which is made up the notes E, G♯, B, and D) can be replaced with a G♯ diminished seventh chord (G♯, B, D, F).
