Greetings, SwordsMaster.

I felt the piece was a little unfocussed, with no real clue as to the source of the protagonist's anger. Was he angry at his recent choice, the peace of the townsfolk, his war experience or all these? I don't get a sense of who the narrator is, or why I should care about him.

I liked the use of the guitar as a metaphor for elusive harmony, just out of his reach - which made me think perhaps it was an unquiet soul that frustrated him. Does he desire the farmer's life, a wife, a hearth, a routine? If so, why is he so angry with the townsfolk?

The style seems to indicate your aim to produce a seventeenth century feel, so there are some inappropriate words (like dad) which reduce the impact. Also, some of your sentences are very unwieldy and difficult to read because they contain too many clauses. The third sentence (begins 'The opportunity...') is a prime example - the paragraph is characterised by short, staccato sentences which one uses to build tension, except for that third sentence where the clauses bunch together and lose the attention and rhythm.

There are some nice touches, such as the hint about the musketeer life, and the longing for the girl he had seen. My personal preference is not to objectify women quite so much as this sentence does -
the dark skin on the neck, and open back, the lean, agile body under the dress and the long legs
and I would use 'her' rather than 'the' to personalise his desire a little - but then maybe you are communicating his brutishness, his inability to really think about a woman as anything but an object. I don't know enough about him to judge - yet.

There are some spelling errors that would benefit from a proof-read.

I get the feeling this is the opening for a longer story, and there may be much to tell. I liked the atmosphere, and the hint of tensions to come. I liked the music image, and wonder what it might portend. If you can make this opening more punchy and focussed, reveal more of the man's character and his distress, it should turn into a fascinating story of a soul-sick musketeer.
