- (mathematics) Of or relating to the work, or theory developed from the work, of German mathematician Bernhard Riemann, especially to Riemannian manifolds and Riemannian geometry.

- Similarly, \hat A(M) is represented by the closed differential form
- \hat A(M) = \sqrt{\operatorname{det}}\left (\frac{R/2}{\sinh(R/2)} \right )
- where R is the Riemannian curvature of the metric g, regarded as an \textstyle\operatorname{End}(TM)-valued two form, and \sqrt{\operatorname{det}} is the Pfaffian, which is an invariant polynomial defined on the Lie algebra of skew symmetric matrices in even dimensions.

- As the preferred metrics applied to symplectic forms are Kähler metrics one could ask for the Riemannian structure which would make the cone with the metric \overline g = dt^2 + t^2g together with the symplectic form \omega into a Kähler manifold. Then \overline g and \omega define a complex structure \overline \Phi. Alternatively, one could ask for a Riemannian metric g on M which would define a Kähler metric h on \mathcal Z via a Riemannian submersion.

- (music) Relating to the musical theories of German theorist Hugo Riemann, particularly his theory of harmony, which is characterised by a system of "harmonic dualism".

- And not only theory: most central European composers of this century were schooled in Riemannian doctrine of one type or another.

- Or take, for example, the rehabilitation by late-twentieth-century North American theorists of Riemannian Tonnetze as a means to navigate the voice-leading intricacies of much chromatic and post-chromatic music.

- The paper connects two notions originating from different branches of the recent mathematical music theory: the neo-Riemannian Tonnetz and the property of well-formedness from the theory of the generated scales.
