Welcome to the

Greater Boulder Youth Orchestras

Challenging Rewarding Fun!

a unique interactive fundraiser


Join in as composer Paul Fowler works with GBYO students and YOU (the audience) to create and perform a piece of music before your very eyes and ears. This unique event will be captivating for everyone, creating a truly memorable experience for all involved.

And this piece will be performed only once, ever!

About the composer:
Sourcing materials parsed from the world’s spiritual traditions and natural beauty, Paul Fowler’s music will “work on you from the inside out” (Philadelphia Inquirer). Fowler draws from his experience as a vocalist, improvising pianist and electronic musician to integrate old and new into “emotionally intense” (Washington Post) works which are “radiant, ghostly and shimmering” (New York Times).

World famous violinist


The Greater Boulder Youth Orchestras and Boulder Phil proudly presented a November 2018 residency with Midori, world-renowned violinist and educator.

GBYO students had the extraordinary opportunity to rehearse and perform with Midori. She worked with each ensemble in GBYO! The residency culminated with her performances of the third movement of Mendelssohn's Violin Concerto with the GBYO Symphony, and the Largo movement of the Bach Double Violin Concerto with the GBYO Wind Ensemble. Midori also performed with the Boulder Philharmonic and engaged the Boulder community with many activities during her residency.

Cicero's Dream, a new work by composer Daniel Kellogg, received its world premiere by GBYO on November 5, 2018.

Midori’s Orchestra Residencies Program is a special project that aims to strengthen the ties of the American youth orchestra to its local adult orchestra, as well as bolster relationships with performers, staff, and the community.

GBYO Appoint Symphony Conductor

Gary Lewis

We are pleased to announce the appointment of esteemed conductor Gary Lewis as Symphony Conductor beginning Fall 2018.

Professor Lewis, Chair of Conducting Studies and Director of Orchestral Studies at the University of Colorado Boulder, played an important role in the creation of the Greater Boulder Youth Orchestras in 2010 and was the founding Artistic Director.

A highly sought after educator and clinician, Mr. Lewis has conducted many All-State Orchestras, the Honor Orchestra of America, and the American String Teachers Association National High School Honor Orchestra. In addition to his work at CU, he is the Music Director of the Midland­ Odessa (TX) Symphony Orchestra, and Principal Guest Conductor of the Boulder Philharmonic.

The coming year will be highlighted by the rare opportunity to participate in a week-long residency with acclaimed violinist and pedagogue Midori. The week will conclude with a performance with Midori on November 5th at Macky Auditorium. Midori will also perform with the Boulder Philharmonic and engage the Boulder community with many activities during her residency. A new work by composer Daniel Kellogg will receive its world premiere by GBYO on the culminating concert.

Audition for GBYO!

Benefits of joining GBYO include:
  • Rehearsals. More than two dozen rehearsals throughout the school year conducted by professionals, during which students learn the finer points and collaborative nature of preparing ensemble music for performance.
  • New friends. Join like-minded excellent young musicians from across Colorado, encompassing approximately 45 different schools.
  • Outstanding conductors. Motivating, challenging, award winning, knowledgeable, in demand, inspiring… GBYO conductors are awesome! Young musicians typically have the opportunity to work with such conductors once or twice a year at a brief festival like All State. GBYO musicians work with these conductors each week!
  • Mentors. Outstanding professional musicians and graduate students work with GBYO students weekly. Read more.
  • Performances in a large ensemble. GBYO has three orchestras and a wind ensemble.
  • Performing works by master composers. Past performances have included works by Tchaikovsky, Beethoven, Bach, Gershwin, Copland, and so many more.
  • Performing world premieres. GBYO ensembles have premiered several new works.
  • Performing in concert halls like Macky Auditorium (or maybe even the Kennedy Center!).
  • Chamber music. Hone your skills in musicianship, leadership, and teamwork.
  • Community. Connect with many people from throughout Colorado. Perform in the community, outside of the concert hall.
  • Mini retreat. Each ensemble gets together for a special afternoon beyond the usual rehearsal time.
  • Collaborations. GBYO collaborates with oustanding professional groups like the Boulder Philharmonic and Colorado Music Festival.
  • Guest musicians. Musicians from professional orchestras like Colorado Ballet, Boulder Bach Festival, and universities often work with GBYO ensembles.
  • Masterclass opportunities. GBYO musicians have performed in masterclasses with musicians like Maureen Murchie, Takacs String Quartet, Brook Ferguson, Augustin Hadelich, Vadim Repin, and more.
  • Life skills. Participation in instrumental music results in profound and lasting positive change in behavior, as evidenced in much scientific research: music students have an easier time staying focused, learning new languages, and thinking abstractly, and have higher level cognitive processes. GBYO rehearsals fully engage students; the skills learned in practicing and preparing carry over to school and all areas of life, and our members use these skills to boost achievement.
  • Opportunities. GBYO students are better prepared for other prestigious opportunities, and have participated in programs like All State Orchestra, Interlochen, and Tanglewood. GBYO graduates have gone on to study music at leading institutions like Juilliard, University of Michigan, and Eastman.
