How can I raise awareness of my YouTube channel?

Hi All,

I recently started making YouTube videos which I think people will find interesting and are not too different to other fairly successful videos which present data in a similar format.

I try to present information that hasn't already been shown. What have you found to be the quickest way to get people to notice what you are doing and build an audience?

Here is my channel: https://www.youtube.com/channel/UCOZ0DOFddLmpaHC0h...

I also created one which teaches little ones how to start playing things on a piano here: https://www.youtube.com/channel/UClJ65z2d4hC7S2DCp...

Thank you!
