The Sequence is a poem that,
On various solemn days of the Liturgical Year,
"Is sung before Alleluia" (OGMR 64).
The word (from sequentia = to continue)
Seems to indicate that this composition
Born from singing on vowel
Which applied to the last syllable of the Alleluia.
The sequence of Pentecost,
Veni Sancte Spiritus,
The day on which the Fiftieth Paschal is closed,
Is a text, composed in Latin,
With which the Church of Roman Rite
Asks for the assistance of the Paraclete Spirit.
Attributed to Stephen Langton (1150-1228),
Archbishop of Canterbury,
Is, along with the Veni Creator,
One of the main hymns to Saint Pneuma.
There are, at present, others:
The paschal sequence: Victimae paschali laudes;
That eucharist Lauda Sion Salvatorem;
And, the Marian sequence Stabat mater.
Outside the days of Easter and Pentecost
Are not mandatory (cf OGMR 40).
This was called "golden sequence"
And its translation reads as follows:
