The 49th annual TubaChristmas 2023 took place at the Sculpture Park outside of the Denver Center of the Performing Arts in Denver on Dec. 17, 2023. Hundreds of tubas, euphoniums and other low-register brass instruments helped to spread holiday cheer under sunny skies and warm temperatures. The event was part of the TubaChristmas 2023, a nationwide series of free concerts performed by local, volunteer musicians who play tubas, euphoniums, sousaphones, baritones and other brass instruments.
