Bass tuba - Sound characteristics
Round, smooth, calm, velvety, hearty, robust, unobtrusive, ponderous, sustaining, gentle, soft, soothing.
D1 – F2
Although the pedal tones speak thanks to the slightly wider bore they are difficult to play and sound very ponderous. For this reason they are only scored pianissimo together with other instruments. The overall effect of the low notes is soft and unobtrusive. The tone is not penetrating, but nevertheless projects very well.
F#2 – F3
Very full-sounding in soft legato phrases. It is the notes within this compass that are used most often.
F#3 – G4
A very loud and powerful tone is possible at this level which can hold its own in tutti passages.
