Theory time! "Quartal Locrian" is a synthetic scale consisting of a half step followed by two whole steps followed by a half step and two whole steps again, repeating ad infinitum so that the scale is non-repeating with respect to actual "pitch quartiles" across the gamut although bound by the strict pattern already mentioned. Potentially allows for wacky quartal harmony, but the composer or improviser is obligated to play pitches that exist in the scale at the octave written, rather than transposing to octave equivalents (aside from tasteful "chromaticism" where warranted). 

From "bottom" to "top", pitches are F - G♭ - A♭ - B♭ - C♭ (or B♮) - D♭ - E♭ - F♭ (or E♮) - G♭ - A♭ - B♭♭ (or A♮) - C♭ (or B♮) - D♭ - D - E - F♯ - G - A - B - C - D - E - F - G - A - B♭ - C - D - E♭ - F - G - A♭ - B♭ - C - D♭ - E♭ - F 

Thanks to Evan Bennet (https://www.youtube.com/user/AnAmericanComposer) for introducing me to this peculiar scale and for the beautiful notation serving as a thumbnail.
