{{Main|Wagner tuba}}
The Wagner tuba is a rare brass instrument that is essentially a horn modified to have a larger bell throat and a vertical bell. Despite its name and its somewhat tuba-shaped appearance, it is generally not considered part of the [[tuba]] family, because the instrument's relatively narrow bore causes it to play more like a horn. Invented for [[Richard Wagner]] specifically for his work ''[[Der Ring des Nibelungen]]'', it has since been written for by various other composers, including [[Bruckner]], [[Stravinsky]] and [[Richard Strauss]]. It uses a horn mouthpiece and is available as a single tuba in B{{music|flat}} or F, or, more recently, as a double tuba similar to the double horn. It is usually played in a range similar to that of the [[euphonium]], but its possible range is the same as that of the horn, extending from low F{{music|sharp}}, below the bass clef staff to high C above the treble staff when read in F. The low pedal tones are substantially easier to play on the Wagner tuba than on the horn. Wagner viewed the regular horn as a woodwind rather than a brass instrument, evidenced by his placing of the horn parts in his orchestral scores in the woodwind group and not in their usual place above the trumpets in the brass section.
