Our Mission
Our mission is to encourage lifelong choral singing, by creating a space where singers of all ages and backgrounds can collaborate, grow, and perform together. Colorado Treble Festival participants receive music to three treble choral pieces in advance. On Festival day, we will gather for a day-long workshop of these songs, followed by a collaborative concert.
At CTF 2025, we hope to exceed our 2024 registration of 100 singers!
Open Invitation
This festival is open to all high school, college, and adult treble-voiced singers. Younger experienced choral singers are welcomed on a case-by-case basis - contact Safonia below for more information. Under the direction and guidance of Christa Fredrickson, MM, participants will collaborate with Safonia and other talented local treble choirs in a full day of singing and collaborative concert.
Workshop
Our morning and afternoon workshop will focus on improving choral techniques and perfecting three festival collaboration pieces. You'll have the opportunity to bond with like-minded treble singers and take your skills to the next level.
