"Liszt's instincts led him to perceive that the Catholic service, which makes a strong appeal to the senses, as well as to the emotions, was eminently suited to musical illustration. He thought his chance lay in the fact that the function assigned to music in the ceremonial is mainly decorative, and that it would be possible to develop still further its emotional side. The Church employs music to enforce and embellish the Word. But the expansion of music is always controlled and in some sense limited by the Word--for the prescribed words are not subject to change. Liszt, however, came to interpret the Catholic ritual in a histrionic spirit, and tried to make his music reproduce the words not only as _ancilla theologica et ecclesiastica_, but also as _ancilla dramaturgica_. The influence of Wagner's operatic method, as it appears in Tannhäuser, Lohengrin, and Das Rheingold, is abundantly evident; but the result of this influence is more curious than convincing. By the application of Wagner's system of Leitmotive to the text of the mass, Liszt succeeded in establishing some similarity between different movements, and so approached uniformity of diction. It will be seen, for example, that his way of identifying the motive of the Gloria with that of the Resurrexit and that of the Hosanna, or the motive of the Sanctus and the Christie Eleison with that of the Benedictus, and also his way of repeating the principal preceding motives in the 'Dona nobis pacem,' especially the restatement, at its close, of the powerful motive of the Credo, has given to the work a musical unity which is not always in very clear accordance with the text.
"In the Hungarian Coronation Mass (Ungarische Krönungsmesse, 1866-7) Liszt aimed at characteristic national colour, and tried to attain it by persistently putting forward some of the melodic formulæ common to music of the Hungarian type which occurs in the national Rakoczy March and in numberless popular tunes--or an emphatic melisma known to everybody through the famous Rhapsodies. From beginning to end the popular Hungarian element is represented by devices of this kind in a manner which is always ingenious and well suited to the requirements of a national audience.
