A collection consisting of three short pieces. It is influenced by the Catalan Renaissance (also known as Renaixença, referring to the literary and artistic revival movement in Catalonia) that emerged in the early 1900s. The collection's title is derived from a prayer book circulated around the late Middle Ages, but its style exhibits the romantic tendencies favored by Granados. All three pieces are given programmatic titles. The themes of "Nightingale" in the second piece and "Suffering" in the third piece also appear in the piano suite Goyescas (the "Nightingale" theme is envisioned in "Quejas, o la Maja y el Ruiseñor", and "Suffering" in "El Amor y la Muerte"). It is also thought that the development of Act 1, Scene 3 of the opera Goyescas, which would later be adapted from the suite, is already present in this collection of short pieces. The score was published in 1912 and premiered in Barcelona on March 23, 1913. The approximate performance time is 7 minutes.

1. En el jardín (In the Garden)

F major. 3/4 time. Andante.

Characterized by few large leaps and smooth, arching motives. Similar to other piano pieces composed during the same period, its style is influenced by Chopin and Schumann.

2. En invierno (La muerte del ruiseñor) (In Winter (The Death of the Nightingale))

E minor. 4/4 time, 2/4 time. Un poco ad libitum.

This piece, in ternary form, maintains an ominous and solemn character throughout. The syncopated rhythm in the left hand repeats as if ticking away time. A descending motive, marked "The Death of the Nightingale", is played ad libitum, and the piece concludes as if fading away.

The "Nightingale" was a favored motif of Granados, and in this respect, a connection can be observed with "Quejas, o la Maja y el Ruiseñor", one of the pieces in the piano suite Goyescas.

3. Al suplicio (In Torment)

4/4 time. Lento.

Unlike the melodic lines seen in the first piece, this piece is constructed from chords and their arpeggios. This expresses the sound of bells tolling to mourn the nightingale that died in the previous piece.

Therefore, this piece is also considered to be related to "El Amor y la Muerte" within the piano suite Goyescas.
