Abstract
A global definition of the Schouten bracket is given, and a global proof of its connection to Poisson structures on manifolds. Some properties are derived, in particular naturality. Then all natural bilinear concomitants of multi vector fields with the same degree behavior as the Schouten Nijenhuis bracket are determined: only constant multiples of the Schouten-Nijenhuis bracket appear.

Keywords: Schouten-Nijenhuis bracket, Schouten bracket

Notes
The methods of proof were later explained in the book: Kolar, Ivan; Michor, Peter W.; Slovak, Jan Natural operations in differential geometry. (English) Berlin: Springer-Verlag. vi, 434 p. (1993). The results are cited but not proved.
