Those of you who play and play well certainly have my admiration. Unfortunately, I do not. My formulative years were spent working as a soda jerk or throwing a paper route instead of taking piano lessons. I was orphaned at an early age.
The arranger allows me as a songwriter to at least show my target audience (performers looking for cover songs) to understand how my song(s) sound when "performed" by an old geezer... LOL!
Like Kingfrog and Mason, I use every possible weapon the arranger brings to the table to "tweak" my songs in selecting the most effective "voices/instruments" for each song. (Many would disagree!)
Thank goodness I don't have to perform live. After 731 songs, I have trouble remembering the lyrics for even the most recent song... Lol!
