i got the foundation of the song but now i want some ideas on how to make it sound and feel good on bass, maybe even some reharmonizing and such the likes
Getting the Foundation is more than half the battle in my opinion.
What I would do, is I listen to the words, and pray and meditate on those words, before you even pick up the bass. Then listen to the song, humming the line as unto the Lord, improvising with my voice as unto the Lord. Then, I would pick up my bass, and let it flow to my fingers. Moving Forward is one of those songs, that most believers could identify with at some point in their life. Feel the emotions of the song, sing the words unto God. Let the emotions it evokes, propel you to creatively make a joyful noise unto God.
Trust me it works.
