the lowest-pitced member of the orchestral brass instrument family. It is considered a low brass instrument along with the baritone and trombone. It often is the root of chords and plays the familiar "oompah" in marches. Is extremely underappreciated by composers and has a solo library vastly made up of pieces that were originally written for another instrument. Tubists, people that play the tuba, are often stereotyped as large hairy German men who like to drink and the majority of IM icons about the tuba are for girls who play the tuba, which is total BS to the male teen tuba player.
The tuba can be a very melodic instrument. No, really. Stop laughing.
