[432] One may add to these monumental pieces the _Sinfonie diverse_ (pp. 140-143 of Vol. XLVIII) and the Concerto in F major in the form of an Overture and Suite (pp. 68-100, _ibid._), but particularly the _3 Concerti für grosses Orchester_ and the _2 Concerti a due cori_ of Vol. XLVII. The _Concerti für grosses Orchester_ have been, so to speak, the sketch books for the Water Music and for the Firework Music. The first Concerto dates from about 1715, and furnished two movements for the Water Music. It is written for two horns, two oboes, bassoon, two violins, violas and bass. The second Concerto in F major (for four horns, two oboes, bassoons, two violins, violas, cellos, basses and organ); and the third Concerto in D major (for two trumpets, four horns, drums, two oboes, bassoons, two violins, violas, cellos, organ) contains already nearly all the Firework Music with a less important orchestra, but with the Organ in addition. The two Concertos for two horns (_Concerti a due cori_) were made from the important choruses of the Oratorios transcribed for double orchestra--ten orchestral parts for the first group, twelve for the second (four horns, eight oboes, bassoons, etc.). Thus the appearance of God in _Esther_: "Jehovah crowned in glory bright," and the connected chorus: "He comes to end our woes." There are there colossal dialogues between the two orchestras. [433] The autograph MS., published in XLVII of the Complete Edition, contains: 2 parts for trumpets with 3 trumpets to a part (_i.e._ 6 trumpets); 3 _Prinzipali_ (low trumpets); 3 drums; 3 parts for horns with 3 to a part (_i.e._ 9 Horns); 3 parts for oboes with 12 for the first part, 8 for the second and 4 for the third (_i.e._ 24 oboes); 2 parts for bassoons with 8 for the first and 4 for the second (_i.e._ 12 bassoons). Total, 70 wind instruments. There were about 100 players for the performance on April 27, 1749. Later on, Handel reproduced the work for concert use by adding the string orchestra to it. [434] Written for 9 horns in three sections, 24 oboes in two sections, and 12 bassoons. [435] It would not be difficult to add other analogous works by Handel and Beethoven. There exists a fine repertoire of popular classical music for open-air _fêtes_. But, nevertheless, it is completely disregarded.
