The Last Verista

The presence of birds in so many of these works was no accident. For Messiaen, birdsong provided intimation of the music of heaven, unclouded by human egotism. He and Ms. Loriod would often go off in search of these natural singers, with Messiaen notating their melodies in the field and later incorporating them into his music.

Loriod and Messiaen

In Ms. Loriod he found a musician who could provide avian qualities of agility and spectacle. “I have,” he once said, “an extraordinary, marvelous, inspired interpreter whose brilliant technique and playing — in turn powerful, light, moving and colored — suit my works exactly.”

It delighted him that her name was homophonous with that of a singing bird: the loriot, or golden oriole, which duly has its place in “Catalogue d’Oiseaux.”

“If Messiaen did not have a Loriod, a pianist wife like her, Messiaen probably would not be Messiaen,” said Mr. Muraro, who is a specialist in the composer’s music.

Ms. Loriod’s performances, in gowns of vibrant color, were exciting to watch, and even more so to hear. In her extraordinary range of timbre, achieved not only by touch but also by the split-second timing of attack and pedaling, she brought to the music the rainbow brilliance it needed. In her sense of rhythm as pulsation, especially in fast music, she gave it the energy it craved.

To some extent those qualities were written into the music under her influence. Messiaen became, from the time he met her, a more assertive and more public composer, and he paid far more attention to the piano.

Yvonne Loriod was born in Houilles, a town six miles northwest of Paris, on Jan. 20, 1924. She had piano lessons from childhood, as did her sister Jeanne, four and a half years younger. Jeanne Loriod, who died in 2001, became a leading exponent of the electronic instrument the ondes martenot.

Yvonne Loriod’s first teacher, Madame Sivade, who was also her godmother, had Yvonne giving monthly recitals as a young girl. By 14 she knew the whole of Bach’s “Well-Tempered Clavier” and all 32 Beethoven sonatas.

She went on to study at the Paris Conservatoire, where she met Messiaen when he arrived in 1942 to take a class in harmony. Along with Pierre Boulez and other classmates, she became a member of Messiaen’s intimate group, with whom he would discuss his music, modern music generally and the music of other continents.

His awareness of Ms. Loriod’s pianistic prowess came soon: in 1943 he wrote “Visions de l’Amen” for the two of them to play on two pianos. That was followed by “Trois Petites Liturgies de la Présence Divine” (“Three Little Liturgies of the Divine Presence,” 1943-44), for women’s choir and small orchestra with solo piano, and “Vingt Regards” (1944). “Visions” was presented by Messiaen and Ms. Loriod in May 1943, when Paris was still occupied; the two other works were performed in early 1945.

After this triptych of sacred concert works, Messiaen produced, from 1945 to 1949, what he called his Tristan Trilogy, on the theme of cosmic love. It was a glorious outburst of love music, and though Ms. Loriod performed in only two of the pieces — the song cycle “Harawi,” evoking Peru, and “Turangalîla” — it seems clear she inspired all three. (The third piece was “Cinq Rechants,” or “Five Refrains,” for small chorus.)

Ms. Loriod had become the focus for musical feelings that the composer had directed toward his first wife, Claire Delbos, in the 1930s but who by the 1940s was suffering a long physical decline.

In the 1950s, all the music Messiaen wrote for Ms. Loriod was bird-inspired: the concerto “Réveil des Oiseaux” (“Awakening of the Birds”), “Oiseaux Exotiques” and the “Catalogue.”

Ms. Delbos died in 1959, and two years later Ms. Loriod and Messiaen were married. A tour of Japan was their honeymoon, remembered by Messiaen in his “Sept Haïkaï” (“Seven Haiku”), for piano and small orchestra. (Ms. Loriod also traced her expertise in Japanese cuisine to that trip.)

In 1962, Ms. Loriod performed all the Mozart concertos at the Conservatoire, whose faculty she joined in 1967. From this point on she concentrated on her pupils — among them Michel Béroff, Pierre-Laurent Aimard and Mr. Muraro — and her husband. Ms. Loriod and Messiaen traveled the world together and welcomed students to their apartment in Paris.

Messiaen’s flow of music for her continued, from big solo parts in the concert-length concerto “Des Canyons aux Étoiles …” (“From the Canyons to the Stars,” 1971-75) to a part in the unfinished “Concert à Quatre” (“Concerto for Four”).

Ms. Loriod recorded everything her husband wrote for her, in many cases more than once, and these recordings will remain an essential part of the Messiaen legacy. Invaluable, too, was the work she did after his death, in 1992, in editing his writings, not least his 4,000-page treatise on rhythm.

Ms. Loriod is survived by a sister, Jacqueline, and a stepson, Pascal Messiaen. Ms. Loriod moved to the Saint-Denis retirement home, in a leafy area, after her cerebral hemorrhage three years ago. There she could hear birds sing, Mr. Muraro said. In recent months, however, she had remained shut inside. “It’s spring and the birds are just beginning to sing now,” he said, but Ms. Loriod did not get to hear them.
