When listing a pair of names (like Laverne and Shirley) or a duo of terms connected by "and" (such as "peanut butter and jelly"), is there a reason why one word order would sound better than the reverse? For example, why would "Kenan and Kel" sound better than "Kel and Kenan"?
Is there any evidence of a convention, tradition or unconscious practice that dictates naming conventions (perhaps similar to how there is a specific order to adjectives depending on what type of description they are)?
Obviously there is the factor of which is more familiar (We've always heard it as "Hall and Oates", so naturally it sounds better that way), but is there a rhythm to which might "roll off the tongue" better?
NOTES ON EDITS
- I've removed references to my own specific case, because it is ultimately irrelevant. Suggestions have been helpful to me personally, but don't help me understand the concept any better.
- I've removed the word "rule" from my question (the "r" word is practically blasphemous in the English language).
