Dave Bonta's "Frontier" is short and strange, and it leaves a lot to the reader. It begins with an odd image: when people settle a sea, they call it a great plain. That suggests a habit of renaming the unfamiliar so it feels solid and ownable. The frontier of the title seems to be that edge where one world is mapped onto another.
The speaker then turns to music "beyond anything / of our never-satisfied life," which suggests a longing for something that ordinary restless wanting can't reach. The last stanzas read like an invitation, perhaps to a loved one or to everyone: let's spend tomorrow together, alone, with no poor people around to "experiment" on. That final phrase is sharp. It hints at a world where the powerless get treated as test subjects.
The mood is dreamy but uneasy. The speaker yearns for peace and beauty, yet the poem seems aware of the cruelty that can hide inside progress and settlement.
