This passage describes a liturgical book containing musical settings of certain Christian prayers known as 'Divine Office' or 'Office of Hours'. The book is titled 'The Divine Office Hymnal', and it features English translations from Latin text used in Catholic tradition.

Key points about the hymnal include:

1. Each song has two versions: one set to Gregorian chant melodies, which are part of a long-standing musical tradition within Christianity; another version uses more modernized metrical (or metered) music instead.

a. The idea behind this dual approach is likely due partly because there may be preferences among worshippers for different types or styles when it comes down how they want their worship services conducted.

2. This particular hymnal represents the fruit of years' worth of work by many individuals who contributed towards making sure all liturgical requirements were met properly before its eventual release into public hands - specifically focusing on bringing about a new translation that better reflects modern understandings while still remaining faithful to established practices passed down through generations past.

3. The General Instruction for the Liturgy of Hours (GILH) is cited as an authority supporting these efforts; it notes that when praying together during office hours, 'the Church unites itself with 'a' hymn... sung in heaven throughout all ages' - highlighting its importance within religious tradition and practice.

4. The new Divine Office Hymnal will be available for purchase this summer, marking a significant milestone as it represents the first opportunity for individuals to acquire physical copies of these newly translated prayer texts since their initial release earlier last year.
