How to write a love song and not really mean it

Can you perform with just a notion of technique and without a sense of sincerity? Working with purity: either just passion or just technique… as a comparative structure to inquire into the question. Is it better to have feeling or a technical sense of the work? We can find examples of great performances of both. Sometimes as we learn more effective techniques in creation, we might get more of a reaction but we can feel more about the technique than the content. Authorial intent: can we know the intention? Do we need to? The audience’s reception: that’s the counterpart to intent of the author. And then the idea of expression. And communication.
