TUBA

The largest instrument of the brass section, the tuba produces a deep and booming sound. It also produces the lowest notes in the brass family. It has 3 valves and looks a little like the horn, except that its bell points upwards instead of outwards.

SOUND PRODUCTION
Tubas are used most of the time to strengthen the bass line, playing the lowest part of the horns or trombones an octave lower. It has a gruff and coarse tone, and rarely plays a tune except for comic or grotesque effects.

RANGE
It is played in bass clef. It is a non-transposing instrument. The most commonly used are the tubas in F and B flat.
