Yes indeed, over 2-3 hours of learning the patterns. It is somewhat difficult to understand the rhythms while you dont have your own Piano yet. First of all you need a Piano so you may able to perform it, your hands are not yet learning on how to and when to press the keys in your own comfortable pace.
Watched this by the way, its pretty legit.
And Im also inspired to play this music. I think thats all for today!
