The speaker describes hearing words that carry no love and no real sound, only a light brushing against the ear. They are pleasant noise, "meaningless, playful sounds," yet someone has used them to preach about "incredible beauty." The gap between what is said and what is felt gives the opening its quiet disappointment. Beauty is being promised, but the speaker doesn't believe it.
The second half widens the view. Nothing is the way it used to be, and even the speaker's memory of the past no longer holds firm. Everything keeps changing, "at every new time." The last line turns to the reader: "Do you understand it, you are finally ready!" It could be read as a gentle challenge or a bit of ironic encouragement, as if accepting that nothing stays fixed is the readiness the speaker means. The mood is reflective and a little wistful, with a calm, resigned tone rather than anger. The title, "Timeless Tones," sits oddly against all this change, which may be the point: the sounds feel timeless, but they have lost their meaning.
