I will demonstrate how to use the B half-whole diminished scale, an octatonic scale created by alternating half and whole steps, to create outside sonorities over the B7 chord while resolving back to F# minor. In jazz, over the B7 chord, we have a variety of altered tones including the root, flat nine, sharp nine, major third, sharp eleven, and flat five, which create tension before resolving back to the F sharp minor chord.
