B♯ Arabian at a glance

Its 1, 3, ♭5 and ♭7 spell a dominant seventh flat five, which is the chord jazz players use it over. Its signature is the flat fifth, reached by a half step from the fourth and followed by whole steps up to the octave.

What makes B♯ Arabian different
The Arabian scale as used here (1, 2, 3, 4, ♭5, ♭6, ♭7) is also called major Locrian: a major lower half under Locrian's upper half. It differs from the Hindu scale only in the fifth, which is lowered. Six of its seven notes form a whole-tone scale and the fourth is the only note outside it, so it sounds like whole-tone with one foothold. Its only half steps are 3 to 4 and 4 to ♭5, both packed into the middle of the scale. On B♯, B♯ Arabian has F♯ where B♯ Hindu has F𝄪; every other note is shared with B♯ Hindu (B♯ C𝄪 D𝄪 E♯ F𝄪 G♯ A♯).
