The Sequence Quartet is a euphonium quartet founded in August 2020 at the Indiana University Jacobs School of Music. Its current members include Josh Bishop, Caleb Harris, Jack Lorens, and Andrew Sallee. The quartet plays a wide variety of works including original euphonium quartet music, wind band transcriptions, and orchestral transcriptions. With multiple composers and arrangers in the ensemble, the group is also committed to creating new works for the ensemble and pushing the boundaries of what the instrument can do. Since its founding, the quartet has completed a regional tour and has been invited as guest performers at numerous Tuba/Euphonium conferences including the 2023 International Euphonium Tuba Festival and the 2023 International Tuba/Euphonium Conference. The quartet is committed to educating future generations of low brass students while also introducing the euphonium to a broader audience.
