Pergolesi's “Stabat Mater”

“"Stabat Mater" de Pergolèse”

Published 1840

Overview

A review written for the Paris Gazette musicale of Alexis Lvov’s arrangement of Pergolesi’s Stabat Mater for full orchestra and chorus. Wagner defends the careful modernisation of old masterpieces, taking Mozart’s arrangement of Handel’s Messiah as the model, and praises Lvov’s restraint while pointing out a few passages where he went astray.

Reviving Old Masterpieces

Wagner begins by praising musicians who study the masterpieces of the past, and stresses that Lvov, the composer of the Russian national anthem, did not claim to improve Pergolesi but to bring his work back into the modern repertoire. At a time when music has taken such divergent paths, he argues, it is a noble duty to return to its sources, and performing old works, adapted if necessary to modern taste, is far more useful than feeble imitations of their style, which tend to copy outdated forms. Admirers of the old school, he warns, often value its imperfect techniques as highly as its great ideas.

Mozart’s Messiah as the Model

Religious music reached its structural peak with Mozart, Wagner says, and he wishes that older works had been passed down in similar form. Mozart’s arrangement of Handel’s Messiah proves how much an old masterpiece can gain in colour without losing its essence. He grants that a huge cathedral performance with hundreds of singers would show Handel’s full historical energy, but notes that Handel himself improvised organ accompaniments, likely for effects Mozart later gave to the improved wind instruments. Anyone undertaking such work should follow Mozart’s example rather than use the full resources of the modern orchestra, which would only travesty the old music.

Lvov’s Orchestration

Lvov, Wagner finds, followed Mozart’s discreet model, adding only trombones, trumpets, drums, clarinets and bassoons, mostly using the clarinets and bassoons, as in Mozart’s Requiem. The hardest task was filling out Pergolesi’s string writing, often in only two or three parts, without spoiling it, and Lvov did this with great tact, his winds bringing out the original melody, as in the “Quae moerebat.” Wagner questions giving the violin part to winds at the start, where the bass then sounds too heavy, and regrets Lvov’s one needless change, an alteration of Pergolesi’s beautiful bass at the start of the second strophe.

The Added Choruses

The boldest step was adding choruses to a work written for two solo voices, soprano and contralto. Strictly, Wagner says, it would have been better to respect the original, but since the solo parts are kept intact and the choruses are handled with skill and understanding, recalling Palestrina’s double choirs, he cannot seriously object. He would have omitted the choral accompaniment and final cadence in the “Fac ut portem,” which sound too much like modern opera. He closes by praising Lvov’s talent and courage in a task that requires the arranger to efface himself completely so that the genius he honours may shine.
