not that hard, but it takes a decent amount of practice unless youre really talented
lots of work
or you could only play the black keys and make life easier
not that hard i never play on anything and i just started summer 2018 and already can do something
from my own experience, i started learning a few months ago, and I never had played before, and I´m learning Bohemian Rhapsody really fast and easily so...
If you have will to learn, then sure you can learn.
Maybe start learning some basic musics with simple chords, chords in general.
The tone system is very easy to pick up on a piano compared to a string instrument.
Example. All 7 church tone scales are built into the design of the piano. Pick any white key, and play the next 7 white key. Knowing this, you can fairly easily transpose the tones to another key.
If you want to learn it, learn it!
I myself am 19 years old as well, and started to learn piano only a year ago as well, unless you're like 60 years old age won't matter that much.
And sure, if you actually want to learn and you're not crazy talented, you'll have to be a bit patient and put in the hours, but believe me, with a bit of work and pleasure you can get very far, even just as a hobby pianist without a lot of talent.
I recently read a book about playing music as a hobby, by this journalist that died in the 90s who was really pasionate about music, and he states that with half an hour or an hour of work a day, you can really become a good musician, and believe me, it's true.
Don't listen to these guys who say that it is not that hard. If you want a decent lvl of piano playing, you have to sacrifice a lot of time and have a ot of talent also
Yes it is hard and you need a piano teacher for it.
