César Franck : Panis angelicus (version with organ accopmpaniment)

César Franck's Panis Angelicus is characterized by an unusually gentle combination of piano or organ accompaniment and vocals, in which the harmony subtly modulates between minor and major keys without interrupting the meditative mood. Particularly noteworthy is the slight rhythmic flexibility in the singing, which allows the singer to adapt the phrasing to the text content, creating an intimate, almost chamber music-like effect.

From the "Messe solennelle" in F sharp minor.
