8 k' e0 l) m# c9 T& t- M+ `3 gThe 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.6 [# H/ T, l9 R% ? d# z
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.
