Journal article (peer-reviewed)abstract
- Identification of unknown organs by Arp Schnitger. Furthermore places of some of those organs are identified or delimitated that were known to have been built by Schnitger according to historical information, but of which the exact whereabout was or is not known. == Information about Schnitger's temperament practice is presented and discussed: An examination report from 1740, written by two organists of Magdeburg (cathedral and St. Ulrich's) shows that not only Schnitger organs were tuned in quarter-comma meantone. They state that this temperament was "unfortunately" the common temperament "here and elsewhere on all large organs". == Translated from German by Ibo Ortgies and by James F. Wallmann. == Peer-reviewed, revised and amended version of articles: – Ibo Ortgies: "Unbekanntes über Schnitger-Orgeln [...]", part 1 and 2 in "Ars Organi", 2016 – Ibo Ortgies: "Nieuws over Schnitger [...]", part 1 and 2, in "Het orgel", 2016 ==== Organs mentioned :== – Schnitger's organ to England, a neglected reference – The organ in the church of the Swedish garrison in Stade, built or repaired by Schnitger – A (house?) organ for a "cantor" in Groningen (possibly an organ for a Mr. "Canter") – A positive organ for Huis Enum (in Eenum, prov. of Groningen) – The organ in "Ensum" (probably Irnsum, prov. of Friesland) ==== Organs in the Duchy of Lauenburg:== – Gülzow, probably Schnitger's organ for "Jonkheer Poteck" – Gudow, rather likely a Schnitger organ – Büchen-Dorf, possibly a Schnitger organ or by another organ builder active in Hamburg between 1695 and 1722 – Niendorf an der Stecknitz, possibly a Schnitger organ or by another organ builder from the Schnitger tradition in the region between Hamburg and Lübeck around 1700 ==== – The organ for the Duke of Sønderborg and Nordborg (Denmark, island of Alsen) – The organ for "Hagelberg" (possibly Havelberg, either Cathedral or city church St. Laurentius) – One to three unknown Schnitger organs for protestant churches in Moscow – Identification of the "Ober-Inspector" in Stade who owned a Schnitger house organ – The organ in "Zelling": Possibly the organ in Rellingen (near Hamburg) ==== Furthermore a document from Magdeburg is presented which demonstrates that in 1740 standard meantone temperament (with eight pure thirds) was regarded as the common temperament in "all large organs" (not only in Magdeburg) by two acclaimed and professional organists.

Bach-Style Keyboard Tuning
- 2006
-
In: Early Music. - 0306-1078. ; xxxiv:4
-
Journal article (other academic/artistic)abstract
- The chain of reasoning in Bradley Lehman's article in Early music, xxxiii (2005), pp.3–23, 211–31, is full of weak links. The notion that Bach followed a mathematical rule when tuning is contrary to relevant documentary evidence that he did not go in for ‘theoretical treatments’ and that ‘mathematizing would never have led to success in ensuring the execution of an unobjectionable temperament’. An expert and musicianly tuner would indeed temper alike the 5ths C–G–D–A–E, but would not feel obliged (as Lehman imagines) to temper some 5ths exactly twice as much as others. The premise that a mathematically rigid tuning-scheme is hidden cryptically in a decorative scroll on the title-page of WTC I is daft, and Lehman's belief that there is only one musically feasible way to interpret this alleged evidence is disproved by the existence of several other such ways besides his (which was based on misreading a serif as a letter). Lehman misrepresents Sorge's account of a certain theoretical scheme from after Bach's death (which he regards as evidence applicable to Bach). No tuning-theorist close to Bach approved of tempering E–G# as much as Lehman does. Lehman's idea that Bach's secret tuning is uniquely beautiful for music by Frescobaldi et al. is outlandish. His one-size-fits-all approach obscures some relevant facts about church-organ tuning in those days. If Bach advised some organ builders about tuning, Zacharias Hildebrandt would be the most likely one, but the meaning of the statement by Bach's son-in-law that Hildebrandt ‘followed Neidhardt’, while clearly ruling out Lehman's scheme, is unclear in some other ways since some of Neidhardt's ideas about tempered tuning changed over the years.

Other publication (other academic/artistic)abstract
- These place marks for (Google Earth) contain the places of organs, that Arp Schnitger (1648–1719) – built new, – enlarged (marked EW), – rebuilt (UB), or – repaired (Rep.; only more substantial repairs). The countries (according to modern borders) in/for which Schnitger organs have built or whereto they were sold, given as a gift ... include Germany, Netherlands, Denmark, Poland, UK (England), Russia, Spain, Portugal, Brazil Schnitger's output is here grouped by decades 1674–1679 1680–1689 1690–1699 1700–1709 1710–1719 In case of instruments which were destroyed (not seldom also the churches were destroyed) the original location was tried to be traced back as precisely as possible. Otherwise the place mark leads to the church in which they have been or are still today. Those of his instruments, which have later been placed in other churches in other towns, are marked as in the following case: The organ, nowadays in Grasberg (near Bremen), was originally built for the church of the Waisenhaus (orphanage) in Hamburg: You'll find the place mark in Hamburg (indicating whereto the organ was moved): Hamburg, Waisenhaus, 1684 (--> Grasberg) In Grasberg you'll find the clue for the origin of the organ. Grasberg (<-- Hamburg-Waisenhaus 1694) House organs (like in Stade or Hamburg, for example) were placed in the middle of the town (in Hamburg for example they are in the lake "Alster")
