There are indeed several ways to help you learn to play the piano. You are no longer limited to employing the services of a piano teacher. Just like so many other things, the internet can give you some real options as well.
I personally think that getting a piano teacher is still the best way to go, because they tailor everything they teach to you and they can and do give you instant feedback on how well you are playing and not only show you how to fix mistakes but how to improve on what is already good. For some, the biggest obstacle for having a piano teacher can be the cost. While it can cost quite a bit to have piano lessons, remember that you are paying for their time. It is also important to state that I think the vast majority of piano teachers charge really reasonable rates. I get it though, the cost of a piano teacher can be prohibitive.
As I said before, there are other options these days. There are various websites where you can pay a monthly fee and they provide you with all sorts of instructional videos, to help you learn to play the piano. From the ones I have looked at, the prices that these websites charge seem to be quite reasonably priced. This tends to be my impression from the few I have taken a close look at. The quality seems to be reasonable as well.
If this is the route you would rather take, then in assessing for yourself which one to chose, do a little research. The things I would look out for is how long they have been around – if they have only been around a short time, they may not be very good. I would also look at how many members they have – some of these websites have thousands of members. You could also look at reviews – look at independent ones rather than the rave reviews they are likely to have attached to their website.
There is another source available and this one is free! It is You Tube, which you can learn how to do just about anything. The real down side of this one is that you would probably end up spending a great deal of time searching for exactly what you want.It might not be the most time efficient option, but it could be a good budget friendly option.
These days there is plenty of choice for all budgets for people who would like to learn to play the piano or need a little refresher.
