Camryn Lafargue
Double Bass
Camryn began orchestra in 5th grade (2013) with the violin, which she studied through 8th grade (2017). In 7th grade she added double bass and quickly realized that that was
where her passion was and as she continued to high school and had to choose, bass was her choice.
Through middle school and high school, Camryn participated successfully in many competitions, auditions, and camps, such as UNT Bass Camp and Summer Strings, UTA Summer Strings, and ISB (International Society of Bassists) Young Musicians Program. She also participated in the Bass and Cello Conservatory and was selected to be a member of the Flower Mound Symphony community orchestra. She was principal of the varsity orchestra at Flower Mound High School all four years. Throughout high school, Camryn had the opportunity to be involved in the world class UNT double bass program, studying with graduate student Cody Williams and highly esteemed professors Gudrun Raschen and Jeff Bradetich, as well as many renowned double bass professors from other universities, such as Jack Unzicker (UTA), Brian Perry (Dallas Symphony / SMU), and
Tyler Shepherd (UTA).
In her high school sophomore year (2018-19), she volunteered teaching private lessons to economically challenged students at a local middle school. The following summer she began officially teaching private lesson students, one of which was first chair at middle school all-region. She also had the opportunity to teach in a group setting with the Bass and Cello Conservatory. Since the Fall of 2021, Camryn has been studying Music Education with a double bass concentration and minor in Music Theory at the University of North Texas. She will graduate in 2026 and plans on getting a Masters in Double Bass Performance. She is excited to continue inspiring young musicians the way others have inspired her.
Outside of teaching, Camryn enjoys spending time with family, playing video games like Final Fantasy and Baulder’s Gate 3, and petting any animals that will let her! She also loves writing/arranging music since she is minoring in Music Theory!
