Dave Bonta's "Sensate" is a tiny scene of closeness between two people at the start of a day. The speaker describes a partner's morning touch as "an admirable strum," which makes her hand sound like it's playing an instrument, and the speaker is both the instrument and the admiring listener. The word "admirable" is a little formal, which gives the line a warm, slightly playful tone, as if the speaker is quietly impressed.
The second stanza shifts to something shared. "Ear to ear" suggests the two are pressed close, heads together, and they "perfect / the next letter." It's hard to say exactly what that means. It might be a letter written together, or a letter of the alphabet traced or spoken between them. Either way, the image points to a private, patient way of communicating. The title, "Sensate," fits: the poem lives in touch and hearing. The mood is calm, intimate, and gently delighted.
