The Phrygiolocrian scale is an eight-tone scale (an octatonic scale) that can be built using the following steps between notes: ½, 1, 1, ½, ½, ½, 1, 1.
One example of the scale is B, C, D, E, F, F#, G, A. This example is shown below in traditional notation and in guitar tablature notation.
This scale is called "Phrygiolocrian" as it is a mixture of the Phrygian scale (B, C, D, E, F#, G, A in the example above) and the Locrian scale (B, C, D, E, F, G, A in the example above).
This scale is the third mode of the Mixionian scale (the bebop dominant scale) or the seventh mode of the Mixodorian scale (the bebop Dorian scale) (or the sixth mode if we ignore the passing tone F#; the mode of the bebop dominant scale starting on F# is sometimes called the seventh mode whereas the mode starting on F is the flat seventh mode and so sometimes the bebop dominant scale is described as having seven modes even though it is an eight-tone scale).
