The E♭ tuba is a brass instrument known for its deep, rich sound. It is commonly used in orchestras, concert bands, and brass ensembles. The E♭ tuba is pitched in E♭, meaning it sounds a major sixth lower than written. This instrument typically has a large, coiled shape and is played by buzzing the lips into a mouthpiece. E♭ tubas come in various sizes and designs, including upright and bell-front models. They are often made of brass and can be finished in silver or lacquer. Notable composers, such as Gustav Mahler and John Williams, have written music that features the tuba prominently.
