Not all the right notes are hit in “Grand Piano,” but for an elegantly schizoid B movie, it’s more B-sharp than B-flat. “Grand Piano.” Rated R for language. Running time: 1 hour, 20 minutes.

The melody abruptly halts on the leading tone of B-sharp while the left hand gets stuck in another barren pattern—this one incorporating the notes D, A, and C-sharp.

Movie review: Elijah Wood portrays a pianist literally under the gun in Eugenio Mira's 'Grand Piano,' an oddball thriller with interesting camera work.
