Beautiful as ‘Orfeo’ is—and the best proof of its enduring beauty is that, after nearly a hundred and fifty years of change and development, it has lost none of its power to charm—we must not be blind to the fact that it is a strange combination of strength and weakness. Strickly speaking, Gluck was by no means a first-rate musician, and in 1762 he had not mastered his new gospel of sincerity and truth so fully as to disguise the poverty of his technical equipment. Much of the orchestral part of the work is weak and thin. Berlioz even went so far as to describe the overture as une niaiserie incroyable, and the vocal part sometimes shows the influence of the empty formulas from which Gluck was trying to escape. Throughout the opera there are unmistakable traces of Rameau’s influence, indeed it is plain that Gluck frankly took Rameau’s ‘Castor et Pollux’ as his model when he sat down to compose ‘Orfeo.’ The plot of the earlier work, the rescue of Pollux by Castor from the infernal regions, has of course much in common with that of ‘Orfeo’ and it is obvious that Gluck took many hints from Rameau’s musical treatment of the various scenes which the two works have in common.
In spite, however, of occasional weaknesses, ‘Orfeo’ is a work of consummate loveliness. Compared to the tortured complexity of our modern operas, it stands in its dignified simplicity like the Parthenon beside the bewildering beauty of a Gothic cathedral; and its truth and grandeur are perhaps the more conspicuous because allied to one of those classic stories which even in Gluck’s time had become almost synonymous with emptiness and formality.
