I make an attempt to rhyme all my songs.
Ditto Queue's post. I use that bit of software also and several other sources for rhyming, being hard copy books.
So far, I've not written a song that doesn't rhyme.
When I read the lryics of a song that doesn't rhyme, I feel like I'm being dangled on a string, just above the water.
Something is missing to me when a song doesn't rhyme. Something doesn't fit.
Rhyming tends to close the gaps, bringing focus on a particular thing. Like Chris said, forms a relationship in some cases.
I don't know the correct names of the types of rhyming, but they are something like;
'Exact'. A sample would be,
Could, would.
And 'Associative'.
An example would be,
can, understand.
I try to use both kinds as it adds some new avenues and rounds off some of the rough edges.
There are a few songs I've heard that don't rhyme each line, and have succeeded.
The only one that comes to mind right now is,
'Gentle On My Mind' by John Hartford. Most people relate to Glen Campbell as the recording artist.
Here it is for those not familar with it's structure and rhyming patteren, or lack of.
It's knowin' that your door is always open and your path is free to walk.
That makes me tends leave my sleeping bag rolled up and stashed behind your couch.
And it's knowin' I'm not shackled by forgotten words and bonds and the ink stains that have dried up on some line.
That keep you in the backroads by the rivers of the memory that
keeps you ever gentle on my mind.
It's not clinging to the rocks and ivy planted on their columns now that bind me.
Or something that somebody said because the thought we fit together walking.
And it's knowing that the world will not be cursing or forgiving when I walk along some railroad track and find.
That your moving on my backroads by the rivers of my memory and for hours your just gentle on my mind.
Though the wheat fields and the clothes lines and junkyards and the highways come between us.
And some other woman crying to her mother 'cause she turned and I was gone.
I still might run in silence, tears of joy might stain my face and the summer sun might burn me till I'm blind.
But not to where I can not see you walkin' on the backroads by the rivers flowing gentle on my mind.
I dip my cup of soup back from a gurgling crackling cauldron in some train yard.
My beards a roughening coal pile and my dirty hat pulled low across my face.
With cupped hands around the tin can I pretend I hold you to my breast and find.
That your waving from the backroads by the rivers of my memory ever smiling ever gentle on my mind.
Two words in each verse.
In my opinion the lyrics are so well defined and able to project the images as the song is sung, that I don't even notice the lack of rhyming.
But the two rhyming words in each verse does bind the verse together, making a comfortable closing.
Another reason it may work with a minimum of rhyming is the structure of the song.
AAAA.
In reference to my above statement about feeling like I'm being left dangling because the lack of rhyming lyrics as I read the them:
In all fairness, I must say that Gentle On My Mind is the only full non-rhyming song I know of that I have not read it's lyrics prior to hearing the song.
Possibly hearing the song first has a bearing on my opinion. I'm not sure.
I've heard other non-rhyming songs after I've read them, and I tend to focus, to my dismay, on the structure, lead and lack of rythmatic rhyming of the song in it's relationship with the music.
Anyway, I rhyme mine because I feel I lack the talent of writers like John Hartford. But I'm gonna try one some day.
