Written and sounding range of THE E flat tuba?

The written range of the E-flat tuba typically spans from the low E-flat (one octave below the bass clef staff) to about G or A (two octaves above the staff), although skilled players can extend this range further. In terms of sounding range, the E-flat tuba sounds a whole step lower than written, meaning its concert pitch range is from D-flat to B-flat. This instrument's rich, warm tone makes it a valuable asset in orchestras, concert bands, and brass ensembles.
