Content is key if you want internet following
now the question, as it has been asked above, is why you want following? Sure you'll get followers for tutorials (maybe one of the easiest, quickest way to gain internet following), but do you want to be known as "the tutorial guy"? or do you want to promote your music?
Patience is also key, patience and quality content, if you post good music, share it also on other social networks, eventually, you'll get a following for that music. But I don't think "luring" followers with "free beats" and a couple of tutorials will benefit your music's exposure by that much, or your credibility.
There are tons of musician's YT channels out there, if you want people to follow you for your music, you got to manage to make the best music you can, hope it's good enough so people will respond to it positively and want to share it with their friends too.
