It was encouraged by the Boehm system built for flutes by Theobald Boehm. Klosé was so impressed by Boehm's invention that he named his own system for clarinets
the Boehm system, even supposing it is alternative from the only used on flutes. This new system was slow to realize focus but continually became the ordinary, and today the Boehm system is used around the globe on the earth except Germany and Austria. These foreign locations still use an instantaneous descendant of the Mueller clarinet called the Oehler system clarinet. Also, some modern Dixieland avid gamers proceed to use Albert system clarinets. Before about 1800, because of the loss
of hermetic pads see History, useful woodwinds may have just some keys to handle accidentals notes exterior their diatonic home scales. The low chalumeau register of the clarinet spans a 12th an octave plus an ideal fifth, so the clarinet needs keys/holes to deliver all nineteen notes during this range. This involves more keywork than on contraptions that "overblow" at the octave—oboes, flutes, bassoons, and saxophones, as an example, which need only twelve notes before overblowing. Clarinets with few keys cannot therefore easily play chromatically, proscribing such a instrument to some closely associated keys. For instance, an eighteenth century clarinet in C may be played in F, C, and G and their relative minors with good intonation, but with creative issue and poorer intonation as the major moved clear of this range. In contrast, for octave overblowing gadgets, an device in C with few keys could a lot more with ease be played in any key.
