[399] M. Volbach has noticed in the overture to the Choice of Hercules, second movement: piano, mezzo forte, un poco più forte, forte, mezzo piano, all in fourteen bars. In the chorus in Acis and Galatea, “Mourn, all ye muses,” one reads forte, piano, pp.—The introduction of Zadock the Priest shows a colossal crescendo; the introductory movement to the final chorus in Deborah, a very broad diminuendo.

[401] Carle Mennicke notices the same sign for decrescendo ((>) on a long note in the Overture to Rameau’s Acanthe et Céphise (1751).
[402] Geminiani says of the forte and the piano: “They are absolutely necessary to give expression to the melody; for all good music being the imitation of a fine discourse, these two ornaments have for their aim the varied inflections of the speaking voice.” Telemann writes: “Song is the foundation of music, in every way. What the instruments play ought to be exactly after the principles of expression in singing.”
And M. Volbach shows that these principles governed music then in Germany with all kinds of musicians, even with the trompettist Altenburg, whose School for the Trumpet was based on the principle that instrumental performance ought to be similar to vocal rendering.

[404] Fritz Volbach reckons for the Concerto Grosso, 8 first violins, 8 seconds, 6 violas, 4 to 6 cellos, 4 basses—and for the Ripienists, 6 first violins, 6 seconds, 4 violas, 3 or 4 celli, and 3 basses.
These numbers are much greater than that of Handel’s own performances. The programmes of a performance of the Messiah at the Foundling Hospital, May 3, 1759, a little after Handel’s death, give only 56 executants, of which 33 were instrumentalists and 23 singers. The orchestra was divided into 12 violins, 3 violas, 3 cellos, 4 oboes, 4 bassoons, 2 trumpets, 2 horns and drums (see Musical Times, May, 1902).
[405] “Leichtigkeit der Bewegung und Beweglichkeit des Ausdrucks,” as Volbach tells us (suppleness of time and fluidity of expression); these are the essential qualities which alone will revive the true rendering of Handel’s works.
[406] 12 Grand Concertos for stringed instruments and clavier (Vol. XXX of the Complete Edition), written from September 29 to October 20, 1739, between the little Ode to St. Cecilia and L’Allegro. They appeared in April, 1740. Another volume, of which we will speak later, is known under the name of Oboe Concertos, and contains six Concerti Grossi (Vol. XXI of the Complete Edition). Max Seiffert has published a well-edited practical edition of these concertos (Breitkopf).
