Parse error: syntax error, unexpected '$triad' (T_VARIABLE)

I'm writing my first Object Oriented script and I'm getting the following error

Parse error: syntax error, unexpected '$triad' (T_VARIABLE) in /var/www/html/unademy/public_html/chord-speller/result.php on line 4

Here is my code

result.php

<?php
  include 'MajorTriad.php'

  $triad = new MajorTriad('C');
  echo $triad->getRoot();
