Fig. 7.29 Tenor sackbut (Anton Schnitzer II, Nürnberg, 1594). EU (2695)
Fig. 7.30 Tenorbass
trombone in 9-ft B with
thumb valve for F (Herbert
Gronitz, Hamburg, mid-late
1950s). EU (4115)
Fig. 7.31 Wagner tuba in
9-ft B (Alexander, Mainz,
early 1930s). EU (2515)
they give an effect of depth comparable to that given by the contrabassoon which is
pitched an octave lower but has weak low-frequency spectral components.
The instruments with least expansion of bore are the slide trombones. The
sackbut with its very narrow bore, high value of B, and small bell flare has a low
transfer function: it requires a significantly higher acoustic pressure amplitude in the
mouthpiece than the wide-bore modern trombone to produce a given performance
