Why Was the Valve Invented?
To make brass instruments chromatic--the idea that the valve was invented as a "mere crook changing device" is a myth.
This article is based on materials published in The Horn Call 28, no. 3 (May, 1998), with related materials to be found published in the Historic Brass Society Journal 9 (1997).
A major point that has frequently been made in the existing literature on the early valved horn is the idea that the valve was invented only to make quick changes of crook--to eliminate the need for the loose crooks of the natural horn to change key--and that only later did hornists realize the chromatic possibilities of the valve. Many sources state this as a fact, and when I started my own research into the history and technique of valved and natural horns in the nineteenth century I thought that it should be very easy to find evidence to support this idea. But the evidence is just not there. Jeffrey Snedeker observed in his 1991 study of Meifred and early valved horn technique in France that "In view of the various comments and accounts surrounding Stölzel's invention and its initial use, it is clear that perhaps an argument as to Stölzel's original intent could be revived." I must second his statement. After examining the evidence I have been forced to conclude that the idea that the valve was invented as a mere crook changing device is a myth. The earliest sources are unanimous in stating that Stoelzel and Blühmel, the co-inventors of the valve, clearly intended to perfect the brass instruments by making them chromatic.
Heinrich Stoelzel (1777-1844), a member of the band of the Prince of Pless, invented a valve which he applied to the horn by July of 1814 [Heyde, part 1, 30]. See Figure One.

[NOTE: While the Stoelzel valve bears his name, it is not entirely clear what Stoelzel's original valve design was. Brass historian Reine Dahlqvist states that Stoelzel originally constructed a double piston "Vienna" valve (Dahlqvist, 133); this design is known with certainty to have been produced by C. F. Sattler of Leipzig by 1819 (ibid, 114--sources which still point to the Ulhmann 1830 patent of this design are out of date). Stoelzel himself had settled on the Stoelzel valve by 1818, but Blühmel's rival patent application of 1818 resulted in both men settling upon Blühmel's box valve (Heyde, ibid, 17-19). See below.]
Stoelzel reported his invention in the following letter, dated December 6, 1814, which was sent to Friedrich Wilhelm III, King of Prussia:
Most illustrious, most mighty King
From the above passage it is crystal clear that the original intention of Heinrich Stoelzel in inventing the valve was to make brass instruments fully chromatic. Note these passages again: "My horn can play all the notes from the lowest to the highest with the same purity and strength without having to stop the hand into the bell.... This device renders the many crooks superfluous and makes it possible for the artist to play all the notes .... I believe that I do not exaggerate in promising your Majesty that by means of these instruments music may be made which will astound the world."
The first published notice of the invention of the valved horn was a short article published in Allgemeine musikalische Zeitung on May 3, 1815, written by composer Gottlob Benedikt Bierey (1772-1840), music director of the theater in Breslau. Bierey had personally examined Stoelzel's horn and gave the invention a very favorable report.
Heinrich Stölzel, the chamber musician from Pless in Upper Silesia, in order to perfect the Waldhorn, has succeeded in attaching a simple mechanism to the instrument, thanks to which he has obtained all the notes of the chromatic scale in a range of almost three octaves, with a good, strong and pure tone. All the artificial notes--which, as is well known, were previously produced by stopping the bell with the right hand, and can now be produced merely with two levers, controlled by two fingers of the right hand--are identical in sound to the natural notes and thus preserve the character of the Waldhorn. Any Waldhorn-player will, with practice, be able to play on it. ...
According to Bierey, the notes which were previously performed stopped with the hand are now "identical in sound to the natural notes." Stoelzel expanded on the same thought as he began the process of applying for a patent on his invention. In a document dated December 29, 1815 Stoelzel stated that
I have, namely, invented a device for the horn, which enables the player, in all simplicity, to produce all notes from the lowest to the highest with the same strength, fullness, and purity, the majority of which were hitherto only obtainable by stopping the hand into the bell and then were only dull and unclear [trans. in Heyde, ibid, 15].
Leipzig music director, organist, and composer Friedrich Schneider (1786-1853) also examined Stoelzel's horn and reported on it in Allgemeine musikalische Zeitung in 1817. He too gave the invention a very positive review, vividly explaining how music would benefit from the invention.
Because of its full and strong, yet soft and attractive tone, the Waldhorn is an extremely beautiful instrument; but, as is well known, it has until now been far behind almost all other wind instruments in its development, being very restricted to its natural notes ....
Schneider states that with valves "it is not only possible but also easy to produce a pure and completely chromatic scale from the lowest to the highest notes with a perfectly even tone." So he too clearly saw the new valved horn as being a completely chromatic instrument, one capable of modulating and performing "passages which previously were absolutely impossible to play."
Figure Two. Blühmel's box valve applied to the tuning slide of the horn, as illustrated in Revue Musicale 2 (1827-28).
Friedrich Blühmel (fl. 1808-before 1845), a miner who played trumpet and horn in a band in Waldenburg, is also associated with the invention of the valve [NOTE: The older literature often describes Blühmel as an oboe player, which is in error]. Blühmel designed a valve independently from Stoelzel, his experiments with what were apparently rotary valves dating back to 1811/12 [Heyde, ibid, 22, 29]. [NOTE: Dahlqvist (122-23), however, believes that this was a tubular valve of some sort--Stoelzel or double piston "Vienna" valve]. While Stoelzel and Blühmel eventually agreed to apply for a common patent on the box valve, a design which Blühmel had developed in 1817/18 [Heyde, ibid, 22, 30] (see Figure Two), a document from Blühmel survives from his separate, rival, patent application of February, 1818, where he states why he wanted to add valves to brass instruments. Blühmel began by relating that the imperfections of the horn and trumpet, on which he had performed since 1808, had led him to experiment. He continued,
The numerous uses of the mechanical forces, which I had an opportunity of seeing during my presence in Upper Silesia, particularly the various air pipes used in the blast apparatus of the high and low furnaces which always led me back to the basic idea of executing an improvement on these instruments, I believe I could use to reach my goal and therefore sought the company of the keepers of the machines and other experts in order to comprehend the closing and opening of the wind pipes, whilst I started out with the idea of which way the air must pass through the tubes of the instrument, to lengthen or shorten according to certain dimensions, in order to make up the missing notes of the compass. ...
We can clearly see as well that Blühmel also wished to fill in "the missing notes of the compass" of the brass instruments--to make the brass instruments chromatic--and that he considered his idea "an improvement on these instruments."
Reviews of performances of the first known work for the valved horn are also notable. The Concertino for three natural horns and chromatic horn by hornist, composer, and conductor Georg Abraham Schneider (1770-1839), was premiered on December 14, 1818; a hornist named Pfaffe performed on the valved horn. This important early work was unfortunately unavailable to the author for study, and is very likely not extant today, but certainly something important can be deduced from the title--it has a part for the chromatic horn. If Stoelzel's invention were seen by the very first performers and composers who worked alongside Stoelzel in Berlin as being merely a crook changing horn of some sort, would the part request an instrument called the chromatic horn? [See the article on the topic of The First Works for the Valved Horn for more information on this work.] It is also very notable that other early works for the valved horn like Schubert's Nachtgesang im Walde (1827) and Auf dem Strom (1828) do not require the use of valves as crooking devices. [See the article on the topic of Schubert and the Lewy Brothers for more information on these works].
One other later document from Stoelzel also deserves a brief examination. He applied for the reinstatement of his ten year patent in August, 1827, and listed the following reasons for needing an extension of his patent.
... most brass players were used to playing on the old instruments and did not want to submit themselves to the drill necessary to learn to handle the new device that makes the instruments chromatic. Also it must be remembered that the pieces of music were not written for the perfected instruments and that first the composers had to get acquainted with the great advantages and possibilities of them, so as to be able to use them adequately.
Again, we see Stoelzel mentioning "the new device that makes the instruments chromatic," and that the old natural instruments had been "perfected."
Stoelzel and Blühmel wanted to make brass instruments chromatic. The idea that the valve was invented as a mere crook changing device is a myth. [NOTE: Much more information on the roots of this myth may be found in The Horn Call version of this article]. Repeating a false idea many times does not make it a fact, even if it does sound plausible. The evidence simply does not support the theory that valves were invented as mere crook changing devices. Only a few works dating from the mid nineteenth century are seen to actually use this technique [be watching for an online version of my article published in The Horn Call Annual no. 9, with sections on "Works By J. R. Lewy" and on "J. R. Lewy and Later Works of Wagner"--some information on this may now also be found in the section of Horn Folklore and "Urban Legends"], and it is abundantly clear that valves were originally seen by Stoelzel and Blühmel as a way to play chromatic passage work not before possible on the horn, and especially as a way to fill in the missing pitches of the natural horn without resorting to right-hand technique. They wanted to "perfect" the horn by making it possible to perform every chromatic note as a open pitch. Stoelzel did not simply wish to make the instrument more portable by eliminating the crooks, although the French were working on this concept in the form of the omnitonic horn [see the related article, What Was the Omnitonic Horn?]. And the earliest surviving works for the valved horn, like Schubert's Nachtgesang im Walde, show no evidence whatsoever that the valve was originally used to make crook changes [see also Schubert and the Lewy Brothers].
Why did Stoelzel invent the valve? In his own words he invented it to perfect the horn so that it could "play all the notes from the lowest to the highest with the same purity and strength without having to stop the hand into the bell."
