The Locrian mode starts on the seventh scale degree. It is the least used mode, in fact you’ll find very few examples of its use. In fact I can’t really remember ever using myself.
In the Key of C : C D E F G A B C the seventh scale degree is B so we have an B Locrian in this Key.
B Locrian: B C D E F G A B The intervals are therefore S T T S T T T
If we compare to B Major : B C# D# E F# G# A# B we can see that the Locrian mode has a b2, b3, b5, b6 and b7 compared to the corresponding major scale. The b5 is quite unusual; the locrian mode only really fits over diminished chords and doesn’t really have any chordal harmony. It has a tense, unresolved sound.

Although the Locrian mode isn’t used much in its own right, chords built on it serve as an interesting alternative to the V chord in a perfect cadence. The tension created by its diminished 5th is resolved when moving to the I chord or to the relative minor at VI. In the key of C, the diminished fifth of B and F in Bm7 b5 is exactly the same as the one in G7. So the Bm7 b5 can resolve up to C or down to Am.

I love it. Actually,I use it a lot in my composition. The other scale I love is the pent atomic scale.
