*MathAcrossCampus* is a quarterly
colloquium series at the University of Washington to showcase
applications of mathematics, with a special
emphasis on the growing role of discrete methods in math applications. The
goal
of this seminar is to expose theoreticians to applied work, to create a
community of mathematicians and users of
mathematics at UW, and to
serve as a guide to students and researchers looking for projects and
jobs in math-related areas by offering exposure to
ongoing math applications in the Seattle area.

The two subjects of math and music are connected in myriad ways, from the rhythm of notes to the frequencies of the pitches. At the advanced level, both mathematical theories and music theories help us understand the other subject. In this talk, we first explore what mathematics tells us about musical instruments, the basic tools of musical practice. In the second half, we flip sides, looking at music theory and how the structure of chords gives us another way to understand topological structures (circles, Möbius strips and higher dimensional tori), some of the basic tools of mathematical practice. Thus the first "movement" connects mathematical theory to musical practice, and the second "movement" connects musical theory to mathematical practice. Throughout, examples played on the violin will illustrate all of these beautiful and surprising connections.

The organizers of MathAcrossCampus are Rekha Thomas, Ioana Dumitriu, and Christopher Hoffman.

MathAcrossCampus is also made possible by the efforts of UW Mathematics graduate students Clayton Barnes, Gerandy Brito Montes de Oca, Christopher Fowler, Matthew Junge, Hon Leung Lee, Harishchandra Ramadas, and Richard Robinson.
