The liner notes to the first Liszt opera album (CDA66371/2) point out that Liszt's contribution to this genre was long viewed with skepticism. This criticism, however, seems petty when one considers the artistic depth of his operatic piano works. It is emphasized that Liszt's compositions demonstrate diverse approaches to the original sources and span many years of his career. His most extensive work, on Meyerbeer's opera Le Prophète, is highlighted, reflecting various aspects of the opera in detailed illustrations.
The second collection comprises paraphrases, medleys, and variations that reveal thematic connections. The "Ad nos" Fantasy and Fugue, an original piece by Liszt, is described in detail and placed in relation to Meyerbeer's music. Furthermore, his works on Donizetti's operas and his Wagner transcriptions are considered high points of his output.
Liszt was deeply committed to promoting Hungarian music, which is evident in his passion for a distinctive Hungarian musical culture. This dedication is reflected in his compositions, including Mosonyi's "Hungarian Opera" with themes from La Belle Hélène. His significant recognition of Hungarian composers and his dedication to national musical education are undisputed.
