Nora Orlandi, also known by the pseudonym Joan Christian (Voghera, June 28, 1933 – Rome, January 1, 2025), was a versatile and fundamental figure in Italian music, distinguishing herself as a singer, pianist, violinist, and composer.

Raised in a family of artists, she graduated in composition, harmony, and singing from the Conservatory of Genoa. Her career took off in 1951 in Rome when she was hired as a violinist in the RAI Orchestra under the direction of Pippo Barzizza, later collaborating with masters such as Lelio Luttazzi and Bruno Canfora. After a phase as a soloist characterized by a melodic style with jazz influences, she founded the Quartetto 2 + 2 in 1952. The definitive evolution came with the creation of I 4 + 4 di Nora Orlandi, an iconic vocal group that became a pillar of Italian record and television productions, also participating in films.

Nora Orlandi was one of the few women to establish herself as a soundtrack composer, excelling particularly in the Western genre. In 1966, she received the Critics' Prize for the soundtrack of Johnny Yuma. She also collaborated with Armando Trovajoli in writing lyrics and was the author of numerous successful advertising jingles.

In the 1980s, she disbanded the vocal group to dedicate herself to teaching. She wrote an influential Modern Singing Method and brought her experience to television as a teacher in the second edition of Amici di Maria De Filippi. She passed away in Rome on January 1, 2025, followed shortly after by her sister Paola, also a singer-songwriter.
