Why it sounds like that
Raise the seventh of C♯ natural minor from B to B♯. The step pattern becomes W, H, W, W, H, 1½, H. The 1½-step between A and B♯ creates the scale's signature tension. Compare with C♯ natural minor to hear the change.
When to use it
Use C♯ harmonic minor over C♯ minor progressions that include G♯ major, like C♯m–G♯–C♯m. It fits classical and neoclassical lines. Try it with C♯ minor and A♭ major.
