I would like to share "Let's pray together" and "let's rejoice together" with you guys. First of all, it's "Let's pray together", a hymn with a great deal of emotion. I played with a 16-beat rhythm. Take a good look at my left hand.
It's too strong to play in the lower note, too light to play in the higher note. So, the left hand moves back and forth at octave intervals. You can adjust the weight in this way.
Also, compare the verse 1 and verse 2 that developed the verse 1.
