From Preface of Trinity Hymnal Baptist Edition, "Of the original 730 hymns, nos. 117 and 350-355 have been changed, and different tunes substituted for no. 281 and 579. Forty-four new hymns (nos. 731-774) have been added, including a Psalter Supplement with a selection from each Psalm mot significantly represented before. The Psalter responsive readings have been omitted. Also, the London Baptist Confession of Faith of 1689 has been substituted in place of the Westminster Confession of Faith and Shorter Catechism."
When marking this "book" as Read, of course I don't mean to imply that I've read all of the lyrics of every hymn contained in this hymnal. However, this is the hymnal that my church sings from, where I have been a member for about 25 years. Not only that, but my husband is the pianist and is the one mainly responsible for choosing the weekly selections, so I am very familiar with its contents. I think it is really sad that in so many churches, hymns have fallen by the wayside, being replaced with praise songs and trite, repetitive ditties.
If you want hymns that contain solid doctrine, this is the hymnal for you. There are many classics and tunes that will be very familiar to those who have been in evangelical churches for any amount of time, but some not so much, and some, to be honest, are not easy or "catchy" tunes. But the purpose of singing hymns is primarily to worship and praise our God, to extol His person, word, and works, and to instruct us in his truths. Some of the most well-known hymn writers are found here: John Newton, Isaac Watts, Charles & John Wesley, Martin Luther, William Cowper, Fanny Crosby, Frances Havergal, and Augustus Toplady.
If you can get hold of a copy of this hymnal, I encourage you to take the time to read the lyrics of these wonderful hymns. Like most hymnals, it's organized by topic, and an index of hymns by subject and occasion is at the end. Even if you are not musical or cannot figure out the tunes, you will find the words to be edifying to your soul and instructive to your heart and mind as you reflect on the God that these hymns speak of.
