International Tuba Day is observed on May 05, 2023. International Tuba Day was created to recognize tubists in musical organizations around the world who have to go through the hassle of handling a tuba.
The tuba is the largest and lowest-pitched brass instrument. Sound is produced by vibrating or "buzzing" the lips into a large cupped mouthpiece. It is one of the most recent additions to the modern symphony orchestra, first appearing in the mid-19th century, when it largely replaced the ophicleide.
A person who plays the tuba is known as a tubaist or tubist. In the United Kingdom a person who plays the tuba in an orchestra is known simply as a tuba player; in a brass band or military band they are known as a bass player. (With material from: Wikipedia)
