Exclude all tagged posts from WP_Query loop

Question

Does anyone know how to exclude all tagged posts from WP_Query loop?

I can do it with 'tag__not_in' for specific tag IDs – see below:

<?php $loop = new WP_Query( array( 'post_type' => 'poetry', 'posts_per_page' => -1, 'orderby' => 'date', 'order' => 'ASC', 'tag__not_in' => array(8, 9) ) ); ?>

But I was wanting to eliminate all tagged posts without updating the tag IDs in the 'tag__not_in'.

Cheers,

Damian

Use the tax_query parameter with the taxonomy set as post_tag. See the following previous answer:
