Very intelligent post, 'ElecTrika-MixTek'. Thanks for this.
American Prayer was experimental though. I love it but it didnt cross my mind as I was more consciously focusing on the song like songs. But I get your point and will not get astray from the idea.
Any more of details on the point a) music can be written for lyrics? I mean How? Like as you mentioned 'An American Prayer', it almost puts a light bulb on my head. If my poetries cant be sung, how about recitations, I mean. But American Prayer werent as flat as recitation, there was an element of musical sing-songness to them. How do I figure that out?
Firstly let's start with your poems. Assuming they are in English can you post two verses and a possible hook or catchy chorus element please.
Certainly we can talk in general terms but for your case we must be specific.
Generally though, we must first observe the genre, style, the meter, and the rhymes as well as the percussive effects of your poetry.
From there we select a suitable form such as the ballad, or the folksong, or the rock anthem and so on... as would be relevant.
Thereafter we must select the instruments and most suitable tones and effects to complement the words and then begin the musical construction of
1. Tempo and rhythm section.
2. Key centre and fundamental melodies.
3. Free variation of melodic ideas on the tonality of the song
4. Decisions about the strongest musical implementation of the lyrics based on musical taste.
5. editing and rounding out of the song with respect to verse and chorus structure, delivery of theme and ending of he song.
