8 – How to control placement of individual fields when theming content type node add / edit form in Twig?

I am trying to theme out the node add/edit form for a custom content type (ex. ‘album’). I have created a form_alter hook in my theme

function mytheme_form_alter(&$form, DrupalCoreFormFormStateInterface $form_state, $form_id) {

  switch ($form_id) {
    case "node_album_form":
      $form('#theme') = ('node_album_edit_form');

that correctly intercepts the node add/edit form and passes it to my theme hook which also finds the correct twig template.

function mytheme_theme() {
  return array(
    'node_album_form' => array(
    'template' => 'node_album_edit_form',
      'path' => Drupal::theme()->getActiveTheme()->getPath() . '/scss/templates/album',
      'render element' => 'form'

in my twig file, ‘node_album_edit_form.html.twig’, I can confirm that changes here alter only the album add/edit form and that I can remove elements, ex:

{{ form|without('advanced', 'footer', 'actions') }} 

What I cannot do but would like to is place the form fields where I want them, ex:

<div class='myfancydiv album-title-field'>{{ field_album_title }}</div>
<div class='myfancydiv album-artist-field'>{{ field_artist }}</div>

because I’m not using the right reference to the field. I’ve tried:

{{ field_album_title }}
{{ form.field_album_title }}
{{ album_title }}

to no effect. Anyone have a working example of this?
