The usual definition of a twisted Poisson algebra involving a 3-form does not seem to refer to a Poisson algebra that is then twisted, i.e. twisting either the commutative product or the Lie bracket. Have I missed where such a discussion occurs?
added tag sg.symplectic-geometry, and changed tag poissonalgebra to poisson-geometry
