I was trying to find a transition between two verses and what I was coming up with was pretty boring and frankly, not fitting right. So I played the arrangement up to that point and stopped as soon as the verse was over. I closed my eyes and started singing in my head what would sound good. I was able to come up with a beautiful sound the first time I tried this.
I’ve definitely heard music in my head before but this time it helped to stop at a part I was stuck on and try to get my brain instead of my fingers to figure it out.
