Schola Cantorum

Paradisi Portae

Paradisi Portae, a distinguished vocal group, was founded in Zaragoza in the spring of 2016. The ensemble’s primary mission is to disseminate a rich heritage spanning over a thousand years of tradition, focusing on Gregorian chant and the earliest polyphonies. Through concerts, collaborations, and recordings, 


The group brings this ancient music to life. Their style is deeply rooted in the principles of Gregorian semiology, meticulously researching original sources and providing contextually accurate interpretations that extend to the performance of Renaissance vocal repertoire.


Notable Performances and Collaborations

Paradisi Portae has performed extensively across Spain, earning acclaim for their participation in prestigious events such as:


Ciclo de Canto Gregoriano de Cuenca

Jornadas de Canto Gregoriano “Ciudad de Ávila”

Festival Camino de Santiago in Jaca

Festival Músiques Religioses del Món in Valencia

Clássica Casalarreina

En clave de Aragón


Among their recent notable projects are collaborations with Novum Organum, reviving the representation of the “Misteri dels Tres Reis d’Orient” at Santa María del Pi in Barcelona last Christmas. They also participated in “Juana”, a multidisciplinary show alongside La Ribot and OCAZEnigma.


Future Projects

Paradisi Portae’s upcoming endeavors include exploring the international polyphony of Ars Nova and the recovery of conventual and monastic repertoire from Aragón. These projects continue their commitment to preserving and revitalizing ancient musical traditions through scholarly research and captivating performances.

Alberto Cebolla Royo

Born in Zaragoza, Alberto Cebolla Royo began his musical training at the Escolanía de Infantes del Pilar. He holds a Superior Degree in Musicology from the Conservatorio Superior de Aragón and has furthered his studies in Gregorian chant through courses offered by the Italian section of AISCGre, learning from esteemed professors such as N. Albarosa, G. Conti, and J.B. Göschl

His training also includes instruction from J.C. Asensio, G. Baroffio, and M. Gozzi in other related fields.

Alberto has performed as a cantor with the Schola Gregoriana Domus Aurea under the direction of L. Prensa and collaborated with P. Calahorra on various medieval Aragonese repertoire research projects at the Institución «Fernando el Católico»

Since 2007, he has been a member of the editorial board of the journal Nassarre. His research focuses on the study of liturgical-musical books and the practice of Gregorian and plainchant, with a deep knowledge of medieval Aragonese repertoire and sources. He has lectured and taught courses on these subjects both nationally and internationally.

After working in the Department of Musicology at the Conservatorio Superior de Música de Castilla y León (Salamanca) since 2010, he became a professor of Musicology at the Real Conservatorio Superior de Música de Madrid in September 2023, where he teaches Gregorian chant and musical paleography

In 2016, he founded the Schola Cantorum Paradisi Portae in Zaragoza, a group dedicated primarily to monodic liturgical repertoire and early polyphonies.

Until very recently, the now less common Gregorian chant was heard in our cities and towns (cathedrals, parish churches, monasteries, and convents), becoming a repertoire that accompanied the annual cycle (Christmas, Holy Week, Easter, Corpus Christi, etc.) and the celebrations of the saints’ feast days. 

The Schola Cantorum Paradisi Portae, through a studied interpretation of some of the most significant pieces of this repertoire, offers the opportunity to recall these melodies for those who once knew them and invites those unfamiliar with them to delight in music that has been carefully created and performed for centuries for the liturgy.

The program presented today delves into the versatility of liturgical monody and the origin of the earliest polyphonies. It includes:

Syllabic chants, such as sequences and hymns.

The delicate adornments of antiphons and responsories.

The more developed and significant pieces of the Proper (introits, graduals, and offertories), which were occasionally embellished both textually and musically with tropes and polyphony, much like the Ordinary pieces (Kyrie).

In summary, this program features recited monodies and more melismatic chants with alternations of soloists, and the initial vertical musical construction, demonstrating the diversity of Gregorian chant: plurality for variety.

An unexpected visit from a unique character will give us the opportunity to delve into the significant liturgy of Christmas Day, beautifully adorned with music from ancient times. 

We will witness the progression of the day’s offices, starting from the nocturnal Matins and concluding with the Second Vespers at the end of the day. From the first piece we will hear, Ave Maria, the angelic salutation par excellence, we will experience a selection of the most significant Gregorian chant pieces for the day:

The perfect measure of simple recitation.

The precise dramatization of texts through their melodies.

The exuberant joy highlighted with extensive melismatic vocalizations.

The embellishment of embellishments with the musical comments of tropes.

The culmination of the day, a grand liturgical-musical expression of the day’s celebration, will be the antiphon for the Magnificat, Hodie Christus natus est (Today Christ is born).

ANTIFONA AD MAGNIFICAT. Hodie Christus natus est (Modus I)

It was the Franciscans who, in the 14th century, began to systematize in Jerusalem a practice that likely dates back to the time of Emperor Constantine (4th century): the custom of commemorating the Stations of Christ carrying the Cross on the way to his crucifixion, walking the Via Dolorosa from the Gate of St. Stephen to the Church of the Holy Sepulchre. 

Due to the difficulty of making a pilgrimage to Jerusalem, and in order to gain the corresponding indulgence for performing this path, by the 17th century, the construction of Calvaries on the outskirts of towns became popular. These often included chapels as stations and were generally marked by small numbered images in the aisles of churches.

Traditionally, the transition from one station to another during the Via Crucis prayer has been accompanied by music. Since there is no stipulated repertoire for this purpose, tradition has dictated the most appropriate chants, such as the popular sequence Stabat Mater, or in more exceptional cases, compositions created to fill this musical void, like organ and choral pieces by renowned musicians such as Franz Liszt’s Via Crucis in 1876. 

Driven by the customary practice of choosing musical pieces whose text corresponds to or recalls the proclamation of the stations, the Schola Cantorum Paradisi Portae has selected a series of Gregorian repertoire works that cite the event of the corresponding station, mention the characters of the Passion, or serve as meditations or reflections to bring us closer to the significance of each stop.

Each musical piece is preceded by the reading of a recently composed sonnet to immerse us in its atmosphere and invite intimate reflection. The sonnets were written by the Valladolid cantor Marcos Castrillo.

The Via Crucis presented here was the result of several processes. The first, upon accepting the commission, was to decide the format: an act so deeply rooted in customs demanded formal parity. Given that the most common form of praying the Via Crucis consists of fourteen stations, what better than the strophic structure of fourteen verses par excellence? This is why the sonnet was chosen as the formal support: fourteen poems of fourteen verses for fourteen stations. The second process was seeking inspiration, and two sources were chosen: one literary and one visual. The literary source was the magnificent Via Crucis that Gerardo Diego wrote in décimas, with some hidden quotes; the visual sources were the processional steps of the Valladolid Holy Week by Gregorio Fernández and Juan de Juni, whose scenes are referenced in the stations.
