THE CHANT IN SILOS

Some of the Gregorian Chant records that impress more emotively are those realized by the monks of Silos who sing them as part of their religious daily offices; its harmony and sweetness flood every corner of the old Abbey. Undoubtedly, his light and calm tone adds a peculiar dye that is helped by the rounded vowels and soft consonants of his Hispanic pronunciation.

The monks of the Silos Abbey have contributed to fill the catalogue of Gregorian Chant records with intense and soft works.

Particularly captivating are the final phrases that often seem to fade away in nothing as if they were absorbed by the stones walls that surround the choir. This is inherent to the music that often is moving away at the end of every phrase, and to the Latin words always accentuated in the penultimate syllable, giving to the chant a feeling of extensive sadness in every phrase.

In the Gregorian collection of Silos, the chant is virile, exact and studied and inevitably attractive. The embellishment and lengthening in the notes, together with the obliged and nasal licuescentia, produce at once a great sensation of peace, this spiritual peace for which every man looks in his interior, damaged for the developing of the daily life.

The popularity of these humble and simple monks has exceeded our borders going around the world; when everything returns to his riverbed and the imposition of the fashion makes him to sink into oblivion, the Gregorian Chant will continue there, since it has done for centuries, to be served as spiritual refuge, independent of our religious tendencies because, as Rvd. Father Abbot Dom. Clemente Serna says, "the spirituality is not scolded by the credence".
