4 Pausch, Die Herkunft Gregor Joseph Werners, 42: ‘Freilich taucht Werner nicht in der Liste der Melkner Stiftsorganisten auf . . . . Vielleicht hat Werner nur die Vakanz von fünf Monaten (29. November 1715–1. Mai 1716) nach dem Tod des ebenfalls aus Ybbs stammenden Mathias Hochedlinger oder zwischen 1720 und 1721 überbrückt, vielleicht war eine Art Substitut. Gegen ein längeres Wirken im Stift spricht eine Absenz unter den Melker Hauskomponisten.’ (It must be admitted that Werner does not appear on the list of organists at Melk Abbey . . . . Perhaps Werner only filled a vacancy for five months (29 November 1715–1 May 1716) after the death of Mathias Hochedlinger, also from Ybbs, or acted as a kind of replacement between 1720 and 1721. The fact that his name does not make an appearance amongst those who were local Melk composers argues against any more lengthy period of activity in the monastery.)

5 The possibility of Werner's having studied with Fux was first mentioned by Pohl in Joseph Haydn, volume 1, 209. However, Pohl based his hypothesis on not very convincing grounds: the fact that Werner had outstanding contrapuntal skills, and that his legacy includes a copy of Fux's Missa Canonica written in Werner's hand. All the later authors who adopted the hypothesis of Werner studying with Fux usually referred to the work of Pohl. More than a hundred years later, Pausch (Die Herkunft Gregor Joseph Werners, 21–23) described a copy of Fux's Gradus ad Parnasum (today in private hands) that belonged to Werner in which the latter entered at the end some important biographical information, including the year and place of his birth. However, studying with Fux is not mentioned there. Thus the best claim that can be made at present is that Werner educated himself using the famous textbook by Fux. In his copy of Gradus ad Parnassum Werner made a number of corrections to and even significant adaptations of Fux's music examples; this provides evidence of intensive use of that textbook, but nothing more than that.

In the Acta Musicalia of the Esterházy family we find a bill concerning the purchase by Werner of instruments and sheet music for the court in Eisenstadt even prior to the move there. Among the musical items obtained by Werner there was, alongside works by Caldara, Paumann, Reinhardt and others, one composition by Fux: the Motetto de Apostolis. See Pratl, Joseph and Scheck, Herbert, Regesten der Esterházyschen Acta musicalia und Acta theatralia in Budapest (Tutzing: Schneider 2004), 25CrossRefGoogle Scholar. However, all of this is insufficient to confirm that Werner had been a pupil of Fux, as postulated by Hubert Dopf in ‘Die Messenkompositionen Gregor Joseph Werners’ (PhD dissertation, Universität Innsbruck, 1956), 4. The state of our knowledge about contacts between Werner and Fux is reported here on the basis of Petermayr, Klaus, ‘Die Beziehungen von Johann Joseph Fux zum Fürstenhaus Esterházy’, in Fux-Forschung: Standpunkte und Perspektiven.

17 On the list of pro mense payments from Flemming's funds in the month of March 1719, immediately after the musician [Peter] Rummel – a violinist in Flemming's ensemble and later violinist at the Dresden Hof-Kapelle – there is a record of ‘Castellan Werner’ with the renumeration of 20 thalers. However, it is difficult to decide whether this Werner ‘Castellan’ and Werner ‘Bassiste’ are the same person. See LAH: shelfmark F. 1280/1 1109, fol. 5.

25 The RISM database records only three compositions signed by the surname Carl alone: Ave regina (H-PH Mus. Jes.117 – copy from 1773), Miserere (SK-KRE 36) and Vesperae de Apostolis (A-Ed G22). In Dokumente zur Esterházyschen Hofmusik (Regensburg: Gustav Bosse, 1981, 296) Ulrich Tank also identifies an Anton Carl (c1717–1784), musician and composer active in the Esterházy ensemble in Eisenstadt. The relationship between Leopold and Anton Carl will need to be established in the future. However, in this context one also has to consider the possibility that the ‘joint’ Werner and Carl composition, Vesperae de Apostolis from the collection in Budapest, may have been the work of Anton Carl from Eisenstadt, and not Leopold Carl from Pressburg.

It should also be added at this point that the list of musicians belonging to the court ensemble of the emperor's widow Eleonora in Vienna for the years 1717–1720 included a violinist called Ambrosius Carl. See Eybl, Martin, ‘Die Kapelle der Kaiserinwitwe Elisabeth Christine (1741–1750) I: Besetzung, Stellung am landesfürstlichen Hof und Hauptkopisten’, Studien zur Musikwissenschaft 45 (1996), 54Google Scholar. The question about whether this musician had a family connection with Carl from the Flemming ensemble remains to be investigated.
