I am 26 years old and am learning the piano on my own. I haven't started to learn sheet music yet. The way I practice is by looking at videos of other people teaching how to play piano songs.
At first, I found it difficult to play with both hands, however gradually over time, this is becoming easier.
My current problem is that I notice my rhythm / rests isn't good, the songs I learn from video, I find it difficult to play in rhythm. I can't think myself of a technique I can use, but I assume it would involve counting in my head, while I'm playing.
And also I find it sometimes hard to find out how long to keep a note pressed, since in the videos it isn't really clear sometimes, I usually start counting how long they press them, to get an idea.
What can I do to get better at rhythm and also is this way of learning Piano bad? I do plan to get lessons at end of this year, but I thought I practice on my own for now.
