How to beat the hymn at 90 beats?

Hymns are mostly four or four beats, and the fourth beat is the main tone. For example, the Lord is my strength: the Lord is my strength, my strength, and the Lord is the strength in trouble. The beginning is the fourth beat: the Lord is. Then the fourth beat: me. The third and fourth beat: the Lord is here. That is to say, when beating the beat, the stress is on the fourth beat: beating; Drop, drop, drop, hit; Put it down, put it down, put it down, fight.
