Low and Lowest
Nov 22, 2014
The musical instrument in the 1928 photo above is a contrabass tuba, considerably larger and lower-pitched than a regular tuba. It is designed to be strapped onto a musician in a marching band and played in its strapped-on position, without need for lifting or rearranging.
The extremely rare instrument in the photo below from Greenwich, England, is a sub-contrabass tuba, which emits sounds an octave lower than those produced by the contrabass tuba. It is probably not intended for use in a marching band.
