This psalm collection is arranged according to liturgical year, with the three-year temporal cycle being followed by solemnities, feasts of the Lord, and national holidays presented in chronological order, everything as it appears in the Oramos Cantando / We Pray in Song hymnal. Most of the musical settings of the 144 pairs of English and Spanish psalm refrains in this collection were composed in 2003 either by Tony Alonso, Ronald Krisman, or John Schiavone. In most cases, each pair of refrains share the same melody; occasionally they are counter-melodies to each other, allowing for both languages to be sung simultaneously. Some refrains were further edited; a few were replaced with new refrains composed by Michel Guimont, Kelly Dobbs Mickus, and Ronald Krisman. The psalm tones of Canadian composer Michel Guimont, which enjoy a wide popularity in North America, are used exclusively in this collection.
The Lectionary psalms use USCCB-approved refrains in both English and Spanish and verses from The Revised Grail Psalms and the salterio of Spain's Conferencia Episcopal Española (CEE). These bilingual lectionary psalms have been included in the Sacred Song missalette program of The Liturgical Press since 2004.
While this collection may be used as a bilingual Lectionary psalter with any musical resource found in the pew, it is specifically linked to GIA's hymnal Oramos Cantando / We Pray in Song.
