One of the greatest helps to memory is real rhyme. Some of the best hymns (old and not so old) were penned, even published, as poems before they were “set” to music. They were written between the rock of trial and the hard place on life’s trail.
By solemn contrast, too many modern “songs” where written on a piano bench, lack good rhyming, and therefore, minus their catchy tunes, are hard to remember.
