FORGET West 47th Street — and the only Jazz in Lindsey Christian’s dull indie soap opera is an aspiring funk singer by that name (Monique Cameron) who lives in a diamond-shaped part of the District of Columbia.

Much to the alarm of her younger dancer sister Leah (Erica Chamblee) — and the disapproval of their father (Clifton Powell) — Jazz is looking for success in all the wrong places.

Wood Harris of “The Wire” gives the only polished performance in “Jazz in the Diamond District,” which employs such devices as a dying parent and pregnancy to dismayingly cliched effect.

Running time: 79 minutes. Rated R (profanity, drugs, rape). At the Quad, 13th Street between Fifth and Sixth avenues.
