(Occasionally spelt “Lochrian” by awkward people)
The modern Locrian is interesting. It exists more as a theoretical entity, but derived just the same as the other modes. It’s very seldom used in music, as there’s not much in it that listeners want to hear, but it does exist and can be applied nonetheless. Moreover, if you’re going to learn the modes, you may as well learn all the modes.
Locrian is the 7th mode in the Major Scale, and most closely resembles the minor formula, so that will be our starting point.
B Natural Minor
R 2 m3 4 5 m6 m7
B C# D E F# G A
In the Locrian mode we flatten the 2 and the 5, (we usually call that a diminished fifth)
B Locrian Mode
R b2 m3 4 b5 m6 m7
B C D E F G A
The oddness of this mode is largely down to the lack of the natural 5th, which can make resolutions just plain difficult. Below is the tab for B Locrian.
As mentioned in the video, entire songs in Locrian are very rare and often unpleasant. The only example I’ve come across of a good-sounding song in the Locrian Mode is John Kirkpatrick’s Dust To Dust.
The Locrian Etude is currently being written, so in the mean time enjoy this 1, 4, 5 progression.
