Octave in liturgy ... Octave of the Assumption

Hagiography can some times be like a treasure trove ... to find an abundance of richness


The octave isn't just found in music, it's also found in liturgy

There are many octaves in liturgy, but the only ones still in practice (that i know of) are:
Octave of Easter - https://en.wikipedia.org/wiki/Octave_of_Easter
Octave of Christmas - https://en.wikipedia.org/wiki/Octave_of_the_Nativity




I started studying octaves in liturgy when i came across the octave of the assumption; there were two notable feast days and one notable rosary recitation during this octave period ...

(1) first day:  assumption - https://en.wikipedia.org/wiki/Assumption_of_Mary

(4,5) midweek:  immaculate heart of mary rosary - https://en.wikipedia.org/wiki/Immaculate_Heart_of_Mary

(8) last day:  queenship - https://en.wikipedia.org/wiki/Queen_of_Heaven

my personal feeling about it, is that it pertains to octave musical language and the eight day concept in Catholicism ...

eight notes in a musical octave is some what different than the eight echio in a musical system because of the octave species is a special music system within the entire music system

From the Catholic Catechism:

( http://www.vatican.va/archive/ccc_css/archive/catechism/p3s2c1a3.htm )

CCC 2174  Jesus rose from the dead "on the first day of the week."¹⁰⁴ Because it is the "first day," the day of Christ's Resurrection recalls the first creation. Because it is the "eighth day" following the sabbath,¹⁰⁵ it symbolizes the new creation ushered in by Christ's Resurrection. For Christians it has become the first of all days, the first of all feasts, the Lord's Day (he kuriake hemera, dies dominica) Sunday:

We all gather on the day of the sun, for it is the first day [after the Jewish sabbath, but also the first day] when God, separating matter from darkness, made the world; and on this same day Jesus Christ our Savior rose from the dead.¹⁰⁶
