Mompou, who spent six years in his native Spain after the outbreak of World War I, composed this piece between 1917 and 1919. It consists of the following five mystical and highly effective pieces. It was dedicated to his mentor, Lacroix. All the pieces are written with extremely simple notation, largely devoid of bar lines. Filled with inspiration and highly original, it received high praise from Parisian critics. Other works from the same period include Suburban and Children's Scenes. The standard performance time is approximately 10 minutes.

1. Energic / No.1 "Energic": Powerful chords across a wide range resonate like bells, shaking the atmosphere. It requires the piano instrument to be properly sounded. In the Lento section, there is a contrasting stillness, within which a song is quietly sung. In the final section, it would be effective to layer sounds, mindful of overtones.

2. Obscur / No.2 "Obscur": A funeral-procession-like melody, beginning with a single note, gradually approaches accompanied by chords. In the next section, written on three staves, the atmosphere completely changes. In the high register, metallic sounds ring brilliantly, while in the middle register, a striking melody is dramatically sung. The bass supports these in the low register, resonating as if pushing upwards. Despite their simple appearance, these create highly effective sonorities. The initial melody reappears, and the piece concludes by fading away.

3. Profond - Lent / No.3 "Profond - Lent": Amidst a melody subtly shifting by major and minor seconds, an E-flat note is struck consistently. These need to be sounded within independent movements. In the middle section, ornamental notes marked "as if a slight breeze blows" are added, imparting a fleeting yet beautiful light to the monotonous rhythm.

4. Misterios / No.4 "Misterios": The most dramatic and mystical piece within Cants màgics. A C note in the left hand, struck independently of the right hand's movement, sounds mysteriously, yet gradually as if foreshadowing something. The subsequent ascending and descending sixteenth-note figures immediately draw the listener into a vortex of fantastical sounds. In the Tranquil Trist section, it feels as if one is hearing distant bells within a remote consciousness.

5. Calma / No.5 "Calma": Chords layered over sustained long notes cause the sound to spread like ripples. The middle section, in contrast, has movement. The piece concludes as the sound of bells gradually recedes into the distance and fades away.
