Three sentences are enough for Nathaniel S. Rounds to turn a musician into a signal tower. The poem looks like a small block of prose, with no rhyme and no regular beat, and that plainness suits it. It begins like a museum label and ends as a question about the human body.
The scene is simple. An old player strikes a hammered dulcimer, "precursor to the piano," and he knows exactly what the instrument will give back. But the title, "Semaphore," makes us read the scene as a message. Semaphore sends meaning across a distance through the movement of arms, and the poem suggests that playing works the same way. The player's arms and hammers become the signalling limbs, and the music is the message passed along. The central idea arrives in the final question: are the vibrations in the steel strings really so different from the blood travelling "from heart to hand"? Both are channels, and both carry a signal from one place to another.
The poem sets this up with careful word choice. "Ever-incessant" is almost a joke on itself, since "ever" and "incessant" say the same thing twice. The phrase is itself repetitive, like hammer blows landing again and again. Then comes "ancient practitioner." "Practitioner" is a doctor's word, not a musician's, and it quietly brings medicine into the room before blood is mentioned. "Ancient" can describe an old man, an old craft, or both, and the poem doesn't choose. The player seems to stand for a long line of people who have done this work.
The second sentence moves from the outside of the scene to the inside. "He knows which vibrations can be elicited" sounds like someone questioning a patient or drawing out a confession. Music is not simply produced here. It is coaxed from the instrument, which implies the instrument already holds it. Then the strings undergo a "reflexive bending." A reflex is an involuntary reaction of nerve and muscle, so the poem lends steel a nervous system. By the time the question arrives, the comparison between metal and flesh has already been prepared. The reader has been half-persuaded without noticing.
The sound of the language supports this. The "s" and "st" sounds in "bending of steel strings" hiss and ring like a plucked wire. The question ends on "heart to hand," two words joined by alliteration and by the route they mark. The phrase compresses the whole act of playing: feeling travels to the hand, the hand strikes, and the string answers. The sentence structure follows the same path, from a statement about an instrument, to a statement about knowledge, to a question about the body. We begin by watching and end by looking inward.
The tone is also worth noticing. The first sentence is cool and informative, almost encyclopedic, with its dash-enclosed aside about the piano. That distance makes the final question feel more intimate. A reader expecting a lesson in instrument history is asked, in effect, to put a hand on their own pulse. The question also isn't a real inquiry. "Do they differ much?" quietly expects the answer "not very." The poem lets the reader reach that conclusion rather than stating it.
The supplied text prints "thej" where "they" is clearly meant, which looks like a slip in transcription. The sentence reads naturally as "Do they differ much," so I have treated it that way.
What makes the poem worth reading is how much it does in so little space. It treats performance as communication, not display. The player is a relay, passing a signal through his own body into wire and out into the air. It also erases the usual boundary between machine and person. The strings seem alive, and the blood seems to behave like a mechanism, a set of channels carrying a charge. Neither is made lesser by the comparison. If anything, both become more mysterious.
A poem this short could easily be thin, but its images keep opening further. A semaphore operator, a doctor, a dulcimer player and a beating heart all end up in the same picture, and the last question leaves the reader to decide where the instrument stops and the body begins.
