As a younger Christian and also now, I have always loved the Book of Psalms. Despite reading and singing it for years, there are many uncharted areas of discovery for me in this lifetime from this divinely inspired book. It was such a precious discovery for myself and our family to begin to sing the Psalms. We sing them in family worship and our congregation includes two metrical Psalms in each worship service.
The tunes are most often designed for congregational singing. I have four metrical Psalm books on my shelf. Sing Psalms (published by the Free Church of Scotland), The Psalms for Singing (Reformed Presbyterian Church in Ireland), Trinity Psalter (PCA in the USA) and The Book of Psalms for Worship (Reformed Presbyterian Church in the USA).
The one we use mainly is Sing Psalms. It is a huge joy to sing Psalms also for personal devotions and to think the church have done so for 3000 years. This does not exclude the singing of hymns with great biblical content. I hope that you can discover the joy of singing metrical Psalms.
Colossians 3:16-17 "Let the word of Christ dwell in you richly, teaching and admonishing one another in all wisdom, singing psalms and hymns and spiritual songs, with thankfulness in your hearts to God. And whatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him".
