In 1812, Iwan Müller, a Baltic German neighborhood born clarinetist and inventor, developed a new sort of pad that was coated in leather or fish bladder. It was hermetic and let makers augment the variety of pad coated holes. Müller designed a new form of clarinet with seven finger holes and 13 keys. This allowed the instrument to play in any key with near equal ease. Over the procedure the 19th century
makers made many improvements to Müller's clarinet, reminiscent of the Albert system and the Baermann system, all maintaining an analogous basic design. Modern contraptions may even have cork or synthetic pads. The final development in the trendy design of the clarinet utilized in many of the world today was introduced by Hyacinthe Klosé in 1839. He devised a unique association of keys and finger holes, which
permit easier fingering. It was inspired 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, though it is various from the only used on flutes. This new system was slow to realize recognition but step by step became the commonplace, and today the Boehm system is used in all places on the earth except Germany and Austria.
