Remember, you can check the document Paschale Solemnitatis on this site, among many on the internet.
The end of Holy Week is a disruption for a number of good Catholics. The regular Mass schedule is interrupted for three days. But there is an alternative:
40. It is recommended that there be a communal celebration of the Office of Readings and Morning Prayer on Good Friday and Holy Saturday. It is fitting that the bishop should celebrate the Office in the cathedral, with as far as possible the participation of the clergy and people. (Cf. Ceremonial of Bishops, 296; GILH 210)
My parishes have not done the Office of Readings. Morning Prayer is important, I think. People do come for it, though not in the numbers seen at daily Mass. Does your diocesan bishop follow this directive of presiding at the Office in the cathedral parish? If I were a cathedral musician, this would be a priority, I think.
This Office, formerly called “Tenebrae”, held a special place in the devotion of the faithful, as they meditated upon the passion, death and burial of the Lord, while awaiting the announcement of the Resurrection.
Night Prayer is also a good choice for Thursday and Friday. But we’ll get there soon enough.
