I am reviewing as part of the Simply Positive Review team. I offer my opinion based on my limited experience. It is only one in a world of opinions and yours to use or ignore.
I would like to go sit by this fountain with you, as you have communicated so well how it is a reflection of mood, and how it enhances emotional expression.
What I like:
I like the words at the end of each stanza: "symphony, sympathy, and harmony."
I like thinking of the water as a source of music. I also like that it ends with a feeling of harmony.
Problems and suggestions:
Third line, first stanza: Music blends (not blend)
Fourth line first stanza: I would consider dropping "a" and saying "in joyful symphony" to improve rhythm.
second stanza, fourth line: I found the words "it's own" disconcerting. They don't enhance my understanding, and, they break the rhythm.
last stanza, last line: read aloud and consider dropping "in." Again, I find this an interruption that doesn't enhance meaning.
I am not a professional writer and don't know if I'm right, but one of my editing rules is read aloud, slowly, then fast to discover bumps and disruptions.
Then I ask myself if the disruption enhances meaning. If not, I find another way to say it. Another way of saying it is eliminate all unnecessary words and keep a clean rhythm. Perhaps you are already following these rules. Your writing is excellent.
I hope you found this helpful. If not, please let me know.
Thank you for sharing.
