Baroque / Classical bassoon after Anonymous / Rockobaur

Baroque / Classical bassoon after Anonymous / Rockobaur


Baroque Bassoon after an early, partly anonymous, original with Wing- joint stamped   Rockobaur,  before 1750-1760 Vienna, Austria.

The original instrument belongs to a private collection. It has amazing acoustical qualities. It is very good  playable with easy fingerings at a’= 415 Hz, but also at a’=430 Hz by using  a slightly shorter Wing-joint and Bocal.

Besides the wing joint which is stamped Rockobaur,  the  other parts of the  instrument  are unstamped.

It is very likely that the unstamped parts of the instrument, the Double bore (Boot-joint) , Long-joint and Bell (Bell-joint) are much older than the stamped Wing-joint and have  been made by a predecessor or teacher of M. Rockobaur.

This may also be the reason of the beautiful warm, baroque sound the instrument has.

M. Rockobaur was the court-musical instrumentmaker of the Esterhazy-court in Austria and delivered instruments to Haydns orchestra.

French baroque bassoon after Prudent Th.

French baroque bassoon after Prudent Th.

Soundtrack:  Danny Bond, Première Sonate for bassoon,E.Ozi

Paris c. 1770

About the Prudent Thierriot replica: My copy of the Prudent Thierriot bassoon is based on an instrument made in the second half of the 18th century in Paris, now in the collection of the Brussels Conservatory museum.
The instrument was the subject of a paper on Acoustics and Mathematics at Nijmegen University(Holland) by Jos de Lange, bassoonist with the Koninklijk Concertgebouw Orkest, Amsterdam.
De Lange found that this instrument is very suitable for baroque music because of the position of the formants (certain groups of harmonics with a relative higher sound pressure) in the sound spectrum of the instrument. The sound is, in fact, similar to that of instruments of the 1st half of the 18th century. The Prudent bassoon  has 5 keys.

Classical Bassoon after J.H. Grenser

Classical Bassoon after J.H. Grenser

Soundtrack: Alberto Grazzi, Mozart, Bassoonconcerto KV 191

Classical Bassoon after J.H. Grenser

Dresden 1764-1843
About the Heinrich Grenser replica: In 1981, Danny Bond and I began to develop a classical bassoon modeled after an instrument by Heinrich Grenser (Dresden, 1764-1813). This instrument belonged to the collection of the Gemeentemuseum at The Hague(Holland). Grenser was one of the best instrument makers of his time.
Our research from 1981-1983 led to the development of the first prototype. In 1995 we made an important improvement in the boot-joint bore which has improved the response of all the instruments I have made since then. My replicas are made of dark brown stained maple with brass keywork and fittings.
The instrument can be heard on recordings of the Mozart bassoon concerto by Danny Bond, Dennis Godburn and Alberto Grazzi.
The Grenser replica has 9 brass keys. pitch: a’=430 hz. The instrument is made of darkbrown stained curly maple.

Posted by admin


I started making bassoons in 1977, later collaborating with bassoonist, Mr. Danny Bond, to develop some models of 18th and early 19th century bassoons. Danny is one of the leading performers on historical bassoons and is principal bassoon of The Orchestra of the 18th Century, and The Philharmonia Baroque Orchestra in San Francisco.
With Mr. Bond I first made reconstructions of bassoons by Prudent Thierriot, Paris (c.1770,) Heinrich Grenser (Dresden c. 1810), and a contrabassoon after A. Eichentopf (Germany, 1714).  Many of these replicas found their way  to musicians all over the world.
Together with Mr. Marc Vallon and later also with Mr. Sergio Azzolini we did a project to reconstruct a German baroque bassoon from  the period of J.S. Bach.
Mr Vallon is principal bassoon of both the Amsterdam Baroque Orchestra and the Orchestre de Champs Elysiis. He also is professor early bassoon in the Paris CNSM.
In 1995, 1996 and 1997 Mr. Vallon and I visited the musical instrument collections of Prague, Leipzig, Neurenberg and Linz to examine the bassoons made by the german makers  I. Poerschman and  J.H. Eichentopf, both working in Leipzig during the first half of the 18th century.
This research resulted in a reconstruction of an Eichentopf bassoon that we finished in the summer of 1998. Many important bassoonists have ordered this instrument already.
After intensive research, together with Mr. Sergio Azzolini, we recently finished the first reconstruction of a four-keyed bassoon.
The instrument is  tuned to a=440 Hz., the Venetian pitch standard at the time of Vivaldi. The instrument possesses a special timbre that is perfectly suited to the language of Vivaldi’s music.
