Join the SJO on a sonic exploration of Sounds from a Quantum Future, inspired by the research of Dr. Steven Rayan and featuring music by Jeff Presslaff

About This Concert

In a one-of-a-kind initiative, the Saskatoon Jazz Orchestra (SJO) brings to you "The Hyperbolic Band: Sounds from a Quantum Future". This unique concert is the brainchild of University of Saskatchewan Mathematics Professor Dr. Steven Rayan, seasoned composer Jeff Presslaff, and SJO Artistic Director Dean McNeill.

Dr. Rayan and Dean McNeill spent several years deliberating on a challenging question: how to make advanced mathematical research accessible and exciting through music? To answer this, they turned to Jeff Presslaff, an experienced composer and a long-standing collaborator with the SJO.

Presslaff's approach is creative yet thoughtful. His compositions translate Dr. Rayan's research in hyperbolic geometry into music, crafting a unique and engaging experience.

The concert promises to be exceptional, not just in its musical interpretations of mathematics, but also in its choice of instruments. Alongside the regular SJO ensemble, we have invited a string quartet, an oboe, and a bassoon. These additions will lend a distinctive sound to the concert that is sure to captivate the audience.

"The Hyperbolic Band: Sounds from a Quantum Future" offers an evening of both intellectual and auditory engagement. We invite you to join us for a concert that explores the intriguing intersections of music and mathematics. It promises to be an engaging, stimulating, and enjoyable experience.
