Concerto Contest


2024 Winner

Keahi Donahue, cello


Keahi Donahue, winner of the Walter and Virginia Charles Concerto Contest, is a junior at Nederland Middle-Senior High School. He started playing piano at age five and especially enjoyed Chopin’s Waltzes. When he was eight, he tried the cello and loved it immediately. At age 13, he decided to focus on cello and quit the piano.

Keahi joined the Greater Boulder Youth Orchestras in 2018 and was principal cellist of its Sinfonia ensemble from 2018-2019, of the Philharmonic from 2019-2020, and of the Symphony since 2021. For a few years, he was a member of the Twintet quartet with his twin sister and twin friends. The quartet busked regularly and was an opener for the Nedfest music festival in 2018. He has studied with Christine Mallery of the Greeley Chamber Orchestra and is now a student of Dr. Charles Lee of the Boulder Philharmonic.

He has performed in masterclasses by András Fejér of the Takács Quartet, Matt Zalkind and Alice Yoo of the Lamont School of Music at the University of Denver, and David Requiro and Meta Weiss of the University of Colorado Boulder. He particularly enjoys romantic era concertos and chamber music and has performed quartets by Haydn, Mendelssohn, Beethoven, and Shostakovich.

He participated in the Colorado Music Festival chamber intensive and GBYO’s chamber music program with Matt Dane. Last year, he won the GBYO Symphony’s Concerto Competition and performed the finale of Haydn’s C major cello concerto in Macky Auditorium. He also sings in his school musical and honors choir, and will travel with the choir to perform in Carnegie Hall in March.

Apart from music, Keahi enjoys research in physics, science conferences, backcountry skiing, Chinese science fiction, alpine ski racing, calculus, Asian food, and travel. He also recently published a research paper with his NOAA mentor on solar flare prediction.


The Greeley Chamber Orchestra organized the Walter and Virginia Charles Concerto Contest in 1982 for high school musicians from northern Colorado (Boulder, Larimer, Morgan, and Weld counties) to promote and publicly recognize outstanding musicianship in our youth. The late Virginia Charles made a generous donation to the orchestra in honor of her late husband, Walter Charles. The concerto contest, created with Virginia's approval, was named after Walter at her request. All cash prizes given to the winners of the contest have come from Mrs. Charles' original and subsequent gifts. Virginia Charles passed away in 1986 and the name of the contest was changed at that time to honor both of these patrons of youth and music.

Walter Charles was the founder and conductor of the Colorado Philharmonic, now known as the National Repertory Orchestra. Virginia, a musician herself, was also instrumental in the success of that fine orchestra as well as assisting Walter in managing "Music Magic," a varied and dynamic program designed to expose young people to music. Together, Virginia and Walter fostered and promoted the musical careers of countless young people and this concerto contest continues that legacy.
