Original Wikitext content:

**Gene Ward Smith** (b. 1947) is a mathematician, music theorist, and composer.

In mathematics, he has worked in the areas of [[http://en.wikipedia.org/wiki/Galois_theory|Galois theory]] and [[http://en.wikipedia.org/wiki/Monstrous_moonshine|Moonshine theory]].

In music theory, he introduced [[http://en.wikipedia.org/wiki/Exterior_algebra|wedge products]] as a way of classifying [[regular temperaments]].  In this system, a temperament is specified by means of a [[Wedgies and Multivals|wedgie]], which may technically be identified as a point on a [[http://en.wikipedia.org/wiki/Grassmannian|Grassmannian]].  He has long drawn attention to the relationship between [[Equal Temperaments|equal divisions of the octave]] and the [[http://en.wikipedia.org/wiki/Riemann_zeta_function|Riemann zeta function]].<ref>Rusin, Dave. "Why 12 tones per octave?" http://www.math.niu.edu/~rusin/uses-math/music/12</ref><ref>OEIS. Increasingly large peaks of the Riemann zeta function on the critical line http://oeis.org/A117536</ref><ref>OEIS. Increasingly large integrals of the Z function between zeros http://oeis.org/A117538</ref> He [[http://www.webcitation.org/67ZUSajSK|early on]] identified and emphasized free abelian groups of finite rank and their homomorphisms, and it was from that perspective that he contributed to the creation of the [[http://x31eq.com/paradigm.html|regular mapping paradigm]].

Gene was among the first to consider extending the [[http://en.wikipedia.org/wiki/Tonnetz|Tonnetz]] of Hugo Riemann beyond the 5-limit and hence into higher dimensional [[http://en.wikipedia.org/wiki/Lattice_%28group%29|lattices]].  In three dimensions, the hexagonal lattice of [[Harmonic Limit|5-limit harmony]] extends to a lattice of type A3 ~ D3.  He is also the first to write music in a number of exotic intonation systems.  See [[Microtonal Music by Gene Ward Smith]].
