Changing Title Element within header.php

Hi all, I would like to change my Title Tag/HTML Title Element within my header.php file. Here’s the title section in my theme’s header.php:

‘<title>
<?php wp_title( ‘|’, true, ‘right’ ); ?>
</title>’

Would it work to input this code to change the title element?

‘<title>
<?php wp_title( ‘|’, true, ‘right’ ); ?>
<?php if(wp_title( ‘|’, true, ‘right’ ) { echo ‘ :’; } ?>
I want this text to be my Title Element
</title>’

Thanks for your help.
