So continuing from the start of the stanza, what are these people doing? They’re talking. They’re having some kind of conversation. They’re communicating with one another. Usually when we talk we’re saying words out loud, we’re using our voices and speaking. But here it says people are talking without speaking, without making literal noises. Somehow people are communicating and having conversations without actually saying words out loud. . However, usually you hear sounds with your ears. But somehow these people are hearing even though there is no sound, and they’re hearing without listening. This means without paying particular attention to the meaning of what they’re hearing. Just because you hear a sound doesn’t mean that you’re paying attention to it. Like where there’s sounds going on in the background but you’re not really listening to them. You know that they’re there but you’re not really paying any attention. So, in the persona's dream he saw: people talking without speaking, people hearing without listening, and finally, people writing songs that voices never shared. If you write something, then you’re putting words on a page that represent, usually, sounds, so that people can read them later. You can write with a pen and paper or with your keyboard and a computer. So, writing songs is writing words for music. He says, people are writing songs that voices never share. We all have a voice , it’s what we use to speak or what you would use to sing songs. But, if voices are not sharing something then they’re not singing them, they’re not communicating them. Sharing literally means to show something to someone else or to allow them to participate in the experience with you. For instance, we can share words and have a conversation, we can share experiences and do some activity together, or we can share things like objects: food, music, songs. But, these voices are never sharing; it means not ever. It’s not happening. People are writing these songs but they’ll never be sung, they’ll never come to life in the form of music and sound. These 3 lines represent a society. As we are expected to follow and adhere to societal laws and the so-called 'norms', but we can see that the persona does not agree with this and wants to rebel against the rules.
