Prague Baroque v.2
Prague Baroque (1642-1673) - A South German Organ Model
While many virtual models of organs have one specific instrument as the template, we decided to take different approach this time. The advantage of presenting a "South German Organ Model" without a direct connection to certain specific instrument is that it is more clearly shown that all the organs of this family in the given period are quite similar to each other and have many common characteristics, in spite of their differences. These common characteristics of the south German organ building school are: an instrument with two short-octave manuals where the Rückpositiv is shaped to be the "smaller brother" of the Hauptwerk for dynamic and spatial contrast; limited pedal division of 18 tones; mild Principals with an expressive speech even on very low wind pressures; sparkling and light sound of numerous mixtures which often include a tierce rank; great variety of flute stops including the typical wooden Copulas -thinner Gedackts- with non-imitable "chiff"; predominant labial character of the instrument accentuated by total absence of reed stops (with the exception of occasional Fagot-like pedal stop with wooden resonators), early appearance of strings. Anyway, it is good to point out at least two instruments which are probably the most excellent examples of the South German organ building school, milestones marking the boundaries of the given period.
Prague is said to be "Mater urbium" (the Mother of towns). The large gothic church of Our Lady before Tyn in the very centre of the city was an eye-witness to all the key adventures of the Czech nation since these events usually took place at the neighboring Old-Town square. The sanctuary is known especially for its Hussite and Utraquist past. Today, many tourists visit the place to find the tomb of Tycho de Brahe. The church is famous also due to its 17th century organ. The instrument has to be called "Mater organorum". Indeed, the masterpiece of Johann Heinrich Mundt (1632-1691) finished in 1673 for the church of Our Lady before Tyn is generally considered to be the THE organ. It is the most typical representative of the Czech organ building. Also, it is one of the best preserved instruments from the 17th century in Europe. If you think of a historical Czech organ, it is the first instrument which comes immediately to your mind. The organ was excellently restored in 1998-2000 by Klais (Bonn) thanks to a massive support of the German foundation (Zukunftsfonds). I can say without any exaggeration that it is the dream of every Czech organist to be allowed to touch this instrument.
Detailed essays on the history of the organ and its restoration are available, based on the account of prof. Hans-Wolfgang Theobald (see the bibliography) who was the leading figure of the restoration process.
However, the greatest south German instruments offer even greater variety of stops, especially reeds. The most notable document of the early Baroque south German organ building is the monumental Johann Georg Freundt (1590-1667) instrument built for the Klosterneuburg abbey near Wien (finished in 1642). 3-manual instrument built for solistic organ playing on high feasts, while retaining most of the characteristics mentioned above including short bottom octaves and very limited pedal, offers reeds of all kinds: full-, half- and short-resonators. We were examining the Klosterneuburg organ and we wanted to record it for Hauptwerk. The organ itself is in perfect shape. It was restored in an exemplary manner by Kuhn (Männedorf, Switzerland) in 1990. However, the blower noise was extreme (I honestly think that it was the loudest blower noise I ever heard) so we gave up. Nevertheless, we at least took the inspiration how a south German reeds should sound and then we decided to add these timbres to the virtual model of our Prague organ model. Therefore, there is the extended version of the Prague Baroque sample set enriched with these Klosterneuburg-like reeds. Therefore, our virtual model cannot be said to imitate one specific organ, rather it tries to imitate the typical south German sound color.

Features and Screenshots
Version 2 enhancements
- Hauptwerk v.3.30 and higher supported.
- newly programmed release tails for the flue stops + some of them newly added for better blending and smoother transitions
- completely new creation of the reeds release tails,. courtesy of Al Morse. The integration of the Klosterneruburg reeds into the Prague church acoustics is thus achieved in greater detail. The extended version of the sample set is now coherent and balanced virtual organ.
- newly created artwork for the screen layout: larger screen resolution (1280x1024px) needed.
- Independent left and right stop jambs added for use with double touch screen.
- A number of voicing corrections.
We offer various temperament charts which are suitable for the Prague Baroque sample set. They are derived from the temperaments found at the Tyn and Klosterneuburg organs.
The temperament proposed by dr. Theobald for the Prague Tyn organ:
This temperament chart is called "Prague baroque after Theobald" in the Hauptwerk temperament directory. Although the authority of the author of this temperament is beyond question, I have serious doubts about its musicality. While seldom used keys as F#-major, C#-major, Ab-major and similar are very well in tune, more often used keys as A-major, E-major, Eb-major are very much out of tune. What is more important, this approach does not seem to match the historical remark of the 19th century maintainer of the organ which is mentioned in the historical essay on the Sonus Paradisi website. For this reason, I slightly modified the temperament, to achieve pleasant A-major, E-major, Eb-major keys while disturbing the F#-major, C#-major and Ab-major to certain extent. I am convinced that this temperament is more musically appropriate as well as historically possible. Both temperament charts (dr. Theobald's and mine) are included in the Prague Baroque sample set so you can judge yourself on the musicality of both versions.
However, the possibility to explore any possible temperament with high degree of precision in conditions that are virtual but still very close to the real situation, this is one of the features of Hauptwerk software which make it valuable tool for the acoustic research and it may be helpful when making decisions about the hypothetical temperaments of historical instruments when these are being restored today. When modifying the temperament, I lowered 4 tones (C, C#, G, G#) so that I arrived at this temperament:
This temperament scheme is called "Prague Baroque modified" in the Hauptwerk temperament directory.
Finally, I merged this experimentally modified temperament with that what we actually found on the organ (surprisingly enough, the real temperament of the organ was not fully in accordance with the proposed temperament by dr. Theobald even though he was the intellectual leader of the restoration). The resulting temperament used as the base of the tuning scheme for Hauptwerk is this:
This temperament chart is then called "Prague Baroque after Zurek" in your Hauptwerk temperaments directory.
The last temperament chart distributed with the Prague Baroque sample set is the Klosterneuburg one, which is taken from the book mentioned in the bibliography, being somewhat milder MeanTone temperament.
- Original version (dry or wet) manuals 45 keys (MIDI: 36-C to 84-C) short bottom octave, pedal - 18 keys, short bottom octave
- Extended version (dry of wet) manuals 54 keys (MIDI 36-C to 91-F), pedal 27-29 keys (MIDI: 36-C to 64-E, or 62-D)
The sample set is offered in two versions -
- Wet version: recorded from a distance of about 6 meters from the pipes using ORTF stereo technique (different location of mics for Positiv and Hauptwerk to achieve good balance and stereo effect), multiple attack and release samples,
- Dry: recorded close to pipes with minimum reverberation, suitable for use in reverberant ambients and /or for artificial reverb addition. By adding various kinds of reverb you may achieve the virtual placement of the instrument into various ambients and you may vary your virtual listening position. The recording is mono, panned virtually in Hauptwerk to achieve stereo effect similar to the real situation.
Dry Original, multisampling, 16 bit compressed: 1899MB.
Dry Extended, multisampling, 16 bit compressed: 2450MB.
Wet Original, multiple samples, full multiple releases, 16 bit compressed: 2482 MB.
Wet Extended, 16bit, compressed, full multiple releases, approx. 4.2GB, using single attack samples and 14bit compression, it is 2.76 GB.
- If you want to get most out of the samples, load it at least in 20-bits (possibly with the memory compression enabled). If you have to make compromises, it is always better to use the memory compression while loading in higher bit depth, rather than using the samples without the memory compression at lower bit depth! The higher the bit depth, the less noise (hiss) introduced by the audio engine in Hauptwerk!
