A♯ Locrian Mode

The A♯ Locrian Mode has a diminished quality due to its Minor Third C♯ and Diminished Fifth E. The Locrian Mode, like A♯ Locrian, is one of seven diatonic modes originally formed using just the natural notes (think just the white keys on a piano) but starting on a particular note, B in the case of the Locrian Mode, which creates a unique sequence of intervals. This mode can then be transposed to any key such as A♯ Locrian Mode in this example. A♯ Locrian Mode is classified as a heptatonic scale as it has seven notes, A♯, B, C♯, D♯, E, F♯, G♯. The A♯ Locrian Mode is also known as a diatonic scale which conforms to specific rules.
