"Machines" is organized in seventeen lines with three, four, or five feet per line. The rhyme scheme is nearly ababcdcd &c, excepting the longish ninth line which does not fit, but does divide the poem into eight lines above and eight lines below it.
If the opening tercet were left off, the poem would be a kind of sonnet, which causes one to wonder why the sonnet form was not chosen. As is, the poem is a kind of sonnet with a three-line introduction, opening with "Dearest," as though it were a letter to a loved one. Perhaps the "dearest" is a loved-one of the speaker, perhaps it refers to the "dear reader."
The poem uses the conceit of comparing an elaborate dance accompanied by a harpsichord to a racing bicyclist riding a twelve-speed bicycle. In each case, there is a machine and human "players" (two in the case of the harpsichord--one playing the instrument, and another dancing). As elegant as the machines--instrument and bicycle--are, it is the cyclist who steers and the harpsichordist who plays.
