Rheuben Allen Clarinet Tuning Ring Set fits both B-Flat and A clarinets. Great to prevent the air from spinning between the barrel and clarinet when pulled out.
Rheuben Allen Clarinet Tuning Ring Set includes 2-1/2mm, 2-1mm, 2-2mm set of 6 tuning rings
Set of 3 tuning rings: 1/2mm, 1mm, 2mm
These rings are made of hard rubber so they will vibrate with the clarinet. There has always been a theory that when you pull out a clarinet barrel and there is space between the clarinet and barrel, then the throat tones will ply flat because of the air spinning around the empty space.
The clarinet is a family of woodwind instruments that have a single reed mouthpiece, a straight cylindrical tube with an approximately cylindrical bore, and a flaring bell. A person who plays any type of clarinet is called a clarinets or clarinettist.
The word clarinet may have entered the English language via the French clarinette (the feminine diminutive of Old French clarin or clarion), or from Provencial clarin, “oboe”. It “is plainly a diminutive of clarino, the Italian for trumpet”, and the Italian clarinetto is the source of the name in many other languages. According to Johann Gottfried Walther, writing in 1732, the reason for the name is that “it sounded from far off not unlike a trumpet”. The English form clarinet is found as early as 1733, and the now-archaic clarionet appears from 1784 until the early years of the 20th century.
There are some different types of clarinets of differing sizes and pitches. The unmodified word clarinet usually refers to the B♭ soprano clarinet, by far the most common type, which has a large range of nearly four octaves. The clarinet family is the largest woodwind family, with more than a dozen types, ranging from the (extremely rare) BBB♭ octo-contrabass to the A♭ piccolo clarinet. Of these, many are rare or obsolete (there is only one BBB♭ octo-contrabass clarinet in existence, for example), and music written for them is usually played on more common versions of the instrument.
Johann Christoph Denner invented the clarinet in Germany around the turn of the 18th century by adding a register key to the earlier chalumeau. Over time, additional key work and airtight pads were added to improve tone and playability.
