In the late 18th century two instrument makers began developing clarinets in the bass register at roughly the same time and independently of one another.
In Paris in 1772 Gilles Lot created a clarinet with several keys and a compass of more than three octaves, which he called a ”basse-tube”.
And in the Dresden workshop of Heinrich Grenser in 1793 a bass clarinet (”Klarinettenbass”) was produced with nine keys and a range down to a written Bb3 (which meant that the lowest sounding note was either Ab4 or Ab3). This instrument and a second bass clarinet from 1795, both pitched to Bb, have survived to the present day. Like the bass chalumeau they have the form of a bassoon. The tubing is very thick, similar to the bassoon’s wing joint, which made it possible to drill the tone holes in the wall at an angle so that they were easily reachable.
At the beginning of the 19th century many workshops were producing a variety of different models with colorful names: in Paris in 1807 Dumas made a bass clarinet that he called a ”basse guerrière”, which, to judge by the name, was intended for military bands. This instrument was later improved by Louis Auguste Buffet. Then in 1812 came the so-called ”basse-orgue” made by François Sautermeister in Lyon; in 1828 it was followed by the bass clarinet of G. Streitwolf in Göttingen; and in 1838 C. Catterini in Padua and P. Maino in Milan came up with the ”glicibarifono”.
The man credited with pioneering the modern straight form of the bass clarinet is Adolphe Sax (1814–1894), who created a version with 22 keys and an entirely straight tube in the 1830s. He also added a reflector which was designed to conduct the vibrations from the downward-pointing bell into the auditorium.
