At
loud dynamics, the Bb trumpet can reach written
F6
and
F#6
F3
is performable on some trumpets by using movable tuning slides.
There
is normally no difference in range between a Bb trumpet and a piccolo
trumpet, but some 4-valve piccolo trumpets do have an additional
major 3rd range
below
the
treble staff (i.e. down to Db3).
