4 Bonanni, Filippo, Gabinetto armonico (Rome, 1722), 106 ‘Un'altro modo si usa nel suonare il Salterio, il suono di cui riesce non meno suave, percotendosi le corde con due bachetti lunghe circa un palmo, e sottili, nel modo indicato nella figura, che raperesenta [sic] una povera fanciulla Tedesca, la quale nel tempo in cui scnvo si vede per le contrade di Roma; onde molti sono allettati ad apprendere l'arti di sonarlo, mentre è ugualmente facile, e dilettevole. Frequente è l'uso di tal'Istromento nella Germania’ Strangely enough, Vivaldi must have had considerable experience of a version of the same instrument in Venice, since the Pietà acquired a salterio in 1706 and another in 1709Google Scholar

20 Giordano, 37, ff. 2-21. At some later point Vivaldi revised the instrumentation of this concerto, eliminating the clarinets and redistributing their material among the other parts; at the same time the lute disappeared from the instrumentation of the second movement. The revisions are indicated directly on the score. Unfortunately, the edition of RV 556 in the Opere strumentali series published by Ricordi (vol. liv) does not adopt either the original or the revised version consistently, so that an unsatisfactory hybrid version results.Google Scholar

21 Everett, , ‘The Manchester Concerto Partbooks’, 359-61 The repertory in Manchester to which the clarinet concertos belong, termed ‘F’ by Everett, contains an aria from Vivaldi's opera Farnace and features a copyist who also worked on the manuscript of Vivaldi's Nisi dominus, RV 608 (Foà 40, ff. 251-98).

26 In statements concerning paper-types and rastrography I have been fortunate to have access to information derived from Paul Everett's continuing research into the manuscript sources of Vivaldi's music Some of this information has been shared during our parallel activity as editors of Vivaldi solo motets for the Nuova edizione critica published by the Istituto italiano Antonio Vivaldi, while many other findings have been very generously communicated in private correspondence Naturally, I alone bear responsibility for any inaccuracies in these statements.Google Scholar

27 The second aria of Cur sagittas, which may be an afterthought or late addition, employs the same paper but a different rastrum spanning 185 2 mm This paper-rastrum combination is also found in the Turin autograph scores of the concertos RV 232 and 386.Google Scholar

29 It is likely that the original version of the Magnificat in G minor for undivided ensemble and without oboes - i.e the version termed by Ryom RV 610b - was composed for the Pietà during the period 1713-17 Certainly, the manuscript of a Vivaldi Magnificat once owned by Zelenka, who acquired it almost certainly during his Venetian sojourn of 1716-17, is listed in the Dresden musician's Inventarium (Dresden, Sächsische Landesbibliothek, Bibl Arch. III Hb 787^d) as ‘Magnificat a 4 C A T B Viol 2, Viola e Basso Contin.’ (no 48 under the rubric ‘Psalmi varn’); unfortunately, the manuscript itself did not apparently pass to the Katholische Hofkirche after Zelenka's death and is now lost (my acknowledgments to Wolfgang Reich for this information) By 1739, the year when the amended version RV 611 was sold to the Pietà, the work would probably have faded from memory, enabling RV 611 to be accepted into the repertory as a new composition It must be questioned whether the version RV 610 (for undivided ensemble but with oboes) ever existed As Ryom has pointed out (Les Manuscrits de Vivaldi, 429), there is no evidence in the autograph score that the instructions (‘P C’, etc) for assigning movements to the respective cori were later additionsGoogle Scholar

33 Settings from Italy of the Gloria, unlike those of the Kyrie and the Credo, seem almost always to have adopted the major mode during the eighteenth century, no doubt with the intention of reflecting the mood of the words A combination of a G minor Kyrie with a B♭ major Gloria would make an exact counterpart to Bach's B minor Kyrie and D major GloriaGoogle Scholar
