Four short lines, hardly a verb among them: Dave Bonta's "Music lesson" reads less like a story than like a dictionary entry written by someone who has stopped being literal. The title promises instruction, and the poem delivers it in the most compressed form possible, a definition. The colon after "Music" works like an equals sign. Music is the first clock, and then, after a pause, it is a bridge in the night. The poem gives two metaphors and leaves the reader to work out how they fit together.
The first metaphor makes a bold historical claim. Before there were mechanical clocks, there was rhythm: a pulse, a footfall, a beat repeated until it became a way of measuring time. The poem doesn't say how this happened, and it doesn't need to. The idea is that music is where time was first felt and counted, long before it was kept by machines. The phrase "before time had discourse / with arms" turns the clock into a character. Time is imagined as something that originally had no body and only later acquired one, the hands of the clock face. The word "arms" is the poem's quiet pun. Clock hands are sometimes called arms, but arms also belong to drummers, dancers and conductors, the people who gave time a shape by moving. The word may carry a darker echo too, since arms can be weapons, though that is an inference and the poem doesn't push it. What matters is that "arms" can be both mechanical and human.
"Discourse" is the most surprising word in the poem. It is a stiff, scholarly word, the language of lectures and formal argument, and setting it beside "arms" is faintly comic, as if time were a professor gesturing as he talks. It also comes from a Latin word meaning to run back and forth, which suits the sweep of a clock's hand. Even if we don't know that, the sound of the word, with its long, grave vowel in the middle, slows the line down.
The line breaks do a lot of the work in a poem with no rhyme and no regular meter. The third line, "with arms.", is the shortest, only two syllables. After the long, slightly breathless second line, it lands like a single beat, and the reader feels the pause before the next line begins. The break after "discourse" also leaves the word hanging for a moment before the arms arrive to complete it. Rhythm and sound are quietly present too. The long "i" of "time" returns in "night," so the first idea and the last are linked by sound across the gap. The hard "k" in "clock" is the poem's tick, and it appears only once, as if the clock were being invented as we read.
The final line changes the poem's logic. Up to now we have been in the world of time, and suddenly we are in the world of space: "A bridge in the night." It is a separate sentence with no verb and no explanation. Bridges connect two sides, so music might link the past to the present, one person to another, or the listener to something just out of reach. Night supplies the darkness and uncertainty: a bridge matters most when you can't see the far bank. There is a musical pun here as well, since the "bridge" is the section of a song that carries you from one part to another. Music, the line suggests, gets us across when the lights are off.
The two metaphors also complement each other. A clock measures time while a bridge crosses it, and between them they describe music as both the thing that counts and the thing that carries. There is a quiet irony in the title as well. A music lesson is usually about counting, tempo and metronomes, yet the poem insists that the pulse came first and the machines are a late imitation.
What makes the poem worth reading is how much it asks of so few words. It takes an everyday object, the clock, and makes us see it as a descendant of something older and warmer. It trusts the reader to hear the pun on "arms," to feel the pause after "arms," and to make the leap into the dark of the last line. The poem teaches by suggestion, which is probably the best kind of lesson.
