pagination within wp_query / wordpress - wordpress

Question

I have written this code for a custom loop in Wordpress, but I cannot seem to get pagination working.
<?php //Template Name: Acapellas ?>
<?php get_header(); ?>
<?php if (is_user_logged_in()) { ?>
<div id="main-content">
<div class="container">
<div class="row">
<div class="col-md-3">
<?php get_sidebar('primary-left'); ?>
</div>
<div class="col-md-9">
<div class="post-<?php the_ID(); ?> post-content">
<h1>Acapellas</h1>
<?php $loop = new WP_Query( array( 'post_type' => 'acapella', 'posts_per_page' => 100 ) ); ?>
<ul class="acapellas row">
<?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; ?>
<?php while ( $loop->have_posts() ) : $loop->the_post(); ?>
<li class="post-<?php the_ID(); ?> col-md-6">
<div class="wrap">
<h2><?php the_title() ?></h2>
<?php the_content(); ?>
<span class="download left"><?php get_attachment_icons($echo=true); ?></span>
<span class="list-date right">First added: <?php the_time('F jS, Y') ?></span><br>
<?php
global $post;
$post_type = get_post_type(get_the_ID());
$post_type_taxonomies = get_object_taxonomies($post_type);
if (!empty($post_type_taxonomies)) {
echo '<ul class="details">';
foreach ($post_type_taxonomies as $taxonomy) {
$terms = get_the_term_list(get_the_ID(), $taxonomy, '', '</li><li>', '');
if ($terms) {
echo '<li>' . $terms . '</li>';
}
}
echo '</ul>';
}
?>
</div>
</li>
<?php endwhile; ?>
</ul>
</div>
</div>
</div>
</div>
</div>
<?php
} else {
wp_redirect( 'http://www.voclr.it/signup' ); exit;
}
?>
<?php get_footer(); ?>

Move your $paged variable outside the loop and include it as a parameter of WP_Query
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$loop = new WP_Query( array(
'post_type' => 'acapella',
'posts_per_page' => 100,
'paged' => $paged,
));
