The tubas are a member of the brass family. The invention of tubas, around 1837, stems from the invention of the piston, which revolutionized the instruments of the brass family. Today it is manufactured in C, F Eb and Bb.

These are the most serious of the brass family, whose range varies depending on the size (length of the tube) and capacities of each tuba and musician. The tone varies depending on the overall geometry, including the proportion of conical or cylindrical tubes over the total length.

To change the pitch sounds, we act on various parameters: lips muscles, quantity and speed of air expelled, all in coordination with fingering different combinations. The use of 3, 4, 5 or 6 valves, or a rotary pallet system (from 3 to 6), can change the length of the tube. Notes are most often written in bass clef for bass tuba and double bass, and in treble clef for the tenor tuba euphonium or saxhorn (type of tuba).
