9 f1 N6 V2 [, ^The Wagner tuba, conceived by Richard Wagner for his Ring of the Nibelung, is made in two sizes, Bb (tenor instrument) and F (bass instrument). In the symphony orchestra two of each instrument have always been used. Because they have a horn mouthpiece they are played by hornists.% |' I2 }$ |' b# ]
Playing technique and position underscore the fact that the instrument is molded entirely on the French horn; the four valves are operated with the left hand, and not, as on all other tubas, with the right. Unlike the horn, however, the bell faces upward.9 _ `( ~) s( l1 k
2 {" y+ w- C4 ^& X9 lAlthough the instrument’s conical tubing (which is less pronounced than the bass tuba’s) means that it belongs to the bugle-horn family, its playing technique and sound characteristics place it among the horns.
