Thank you very much for all your replies.
When I look at and listen to the songs again, I find this one to be the simplest one with very repetitive bass/left-hand:
Some of my long-term goals in piano is being able to play the following pieces (as many notes as possible at any giving time, from what I can see, some combination seems to be impossible with just two hands):
Or as when someone actually plays it:
This is a nice version of He's A Pirate I also want to learn as one of my long-term goals with piano:
As you can see, I have a very strange, nostalgic and almost childish taste of music played on the piano!
I will now reply to each one to show my appreciation.oldlearner: Thank you very much for providing those resources! I found most of these in PDFs now. Will print them out before I receive my digital piano so I have them.
My parents have an untuned acoustic piano and I will also leave my keyboard there so hopefully my unemployed father will have something better to do which is also good for his age (54) by playing piano and learning simple notes. My mom used to sing in church and can sing correctly so she will also love that I learn reading&playing notes since she has a huge stack of church songs and melodies in note form.
Bartók - Mikrokosmos Book I, seems pretty basic which is great for me who can only see one note at a time as of now. From what I remember from years ago, you are suppose to be able to read one bar at a time after enough practice or was it one row with bars? (how do you do it?)
Johannes Rövenstrunck - Miniatures op.1, seems also pretty basic which is great for me. My biggest challenge (I think) will be when I have to read&play more than one notes at a time (e.g. an accord on left-hand and maybe two different notes in right-hand).
H. Berens - 50 Piano Pieces for Beginners, op.7, seems to escalate pretty quickly in terms of how many notes played at a given time and per bar. So, I assume this would be like a step up from the two other ones? (although I found several books from Bartók).
Would be interesting to hear what piano teachers think of these piano beginner books. Thank you very much for your reply!
adodd81802: Thank you very much for your reply. I think we have an misunderstanding here. I don't go to the gym to necessarily exercise muscles for piano playing (but I don't exercise my underarms so I should start doing that!), I do it for my whole body, for general health purposes mainly.
It is nonetheless an interesting comparison, particularly when we think about the rest part when going to the gym. You can exercise/train too much and do more hurt to yourself than good, and I wonder if this is also the case with piano playing? At the gym I do exercise my back and shoulders and I always concentrate to have an open, shoulders rolled back, and straight posture, just for the sake being.

What are your opinions and experiences regarding piano practice and resting? Do you think one can train/exercise too much on the piano? I will look up those softwares and see whether I can benefit from them to make them worthwhile to afford them.
I do not exactly know what you mean with (I do not know so much of the music lingo yet, I have just played and listened mostly these years) 1-2-3 beat. Do you mean that you count 1,2,3 as one bar?
I have never heard of the word "trill" and when I translate it I see that it seems to mean "a note that alternates rapidly with another note a semitone above it". Does that mean like one white key plus another white key with its sharp/black key above it?
Thank you very much once again for your reply!
listesso_tempo: How do I understand "not being able to focus on both hands at the same time" with "playing with both hands slowly"? Is that learning style false in other words? Is the optimal way to play first left-hand, then left-hand and then both slowly until you just nail it?
Your first provided YouTube video with real notes is just way too complicated for me right now. However, for future reference, is it a good finger dexterity exercise? Does it include jumps exercises?
I'm afraid that I do not understand what you mean (yet) with M1: 1-2-3... M2: 1-2-3 and so on. I do not know all the music lingo and way of communicating with other pianists yet, and I apologize for that.
Your second provided YouTube video appears to be a fugue, which I remember from music class in elementary school, and that seems to really exercise even one's separate fingers for each hand. What I wonder is how this, very abstract sounding music according to me, would translate when wanting to improve one's general piano abilities? Would it help with dexterity, jumps and so forth?
Just like my comparison with the gym; would it exercise certain "piano muscles" (not body muscles, but piano skills) or would it just make you better at that particular piano piece and not really benefit otherwise from it? I do not intend to learn classical pieces, so that is why I ask this.
Thank you very much for your reply!
