How to accompany a hymn

The Enyou song in your example is in the key of E, (of course, it can be raised or lowered) 1=4/4, and the notation is 5.565 3 1 | 1-60 | ... If you want to accompany with your left hand, you can usually take the first three chords of a triad 5- 7 and the second 57-. You can also take arpeggios, that is, turn your fingers with your left hand. Because this hymn is used to praise the Lord and cooperate with the choir, you can use the main rotation to match the simplest chord. Don't be too fancy. The use of chords is regular. Look at it. Look for it with your piano. If you have any questions, please contact me at 1 132 1658.
