The Boulder Phil and the City of Boulder Open Space & Mountain Parks (OSMP) have created an ongoing collaboration to connect community members with the natural world through music. This partnership includes guided musical hikes designed to complement specific works to be performed by the Boulder Phil. The hikes are free and open to the public.

Viola with High Altitude
Sat. Sept. 29, 9 a.m.–noon

Join Matt Diekman, violist from the Boulder Phil, for an easy hike along one of Boulder’s spectacular trails. Matt will guide the conversation through Western music’s connection of the natural world, and specifically to how stringed instruments are constructed and the mechanics of how they work (very much related to natural materials and awareness of the environment). We will listen to Matt play his viola in one of OSMP’s naturally-formed stone amphitheaters! The location will be provided with reservations. details

Reservations open Sept. 1. Please reserve spaces here: 


Meet the Planets!
Oct. 5, 11 & 12, 7:15–10 PM

The Boulder Phil’s Infinite Space concerts (Oct. 13 & 14) showcase Gustav Holst’s glorious work The Planets. Take a pre-concert tour of the solar system through a large telescope with City of Boulder Open Space naturalist Dave Sutherland while sampling excerpts from this stirring music. After seeing the moons of Jupiter, the rings of Saturn, the polar caps of Mars, and distant Uranus and Neptune, you will be fully prepared to enjoy the concert like an expert! Meet at Boulder Valley Ranch trailhead. Follow this link for a map: details

PLEASE NOTE: Telescope viewing is weather-dependent: if there is a 50% cloud cover or more at the time the program starts, it will be canceled and may be rescheduled for another night at short notice. You can find the latest updates at


The Secret of Wind and Birds
Oct. 28 & Nov. 3 from 8:30–11 AM

On Nov. 4, the Boulder Phil will play composer Tan Dun’s intriguing work Passacaglia: Secret of Wind and Birds. Throughout the piece, the orchestra emulates the sounds of the wind, ocean and bird songs in surprising ways (and audience members’ smartphones also get involved)! Join City of Boulder Open Space and Mountain Parks naturalist Dave Sutherland for a pre-concert hike to explore this imaginative music, as well as other composers who have captured the essence of wind, water and birds. Meet at the East Boulder Community Center.  details


The Music of Landscapes 
Feb. TBA

Rich with meaning and memories, our favorite landscapes speak to us in many ways: joy, beauty, nostalgia, awe, even dissonance. How do composers capture the essence of the land in music? Join OSMP naturalist Dave Sutherland for a beautiful hike to sample music that invokes our sense of place, including works by home-grown composer Kristin Kuster, whose composition Dune Acres will be featured at the Boulder Phil concert on March 2. How would you express your memories of your favorite landscapes through music?
