Learning to play piano is not really that difficult. There are many piano teachers who give piano classes on hourly basis or for a fixed number of classes every month. If you love playing piano, then there are advanced classes too, that you can take of. There are many advantages of these piano schools.
To start with one gets the technique right if they learn from a professional piano instructor who is certified as will be the case for music schools. Right technique is always important, for example the position of the palm and the wrist and the fingers etc. A good instructor can also help students to get over the one hand habit they have and develop the weaker fingers too. This is most essential for playing piano.
Another important thing that piano students learn is to follow notations from piano sheets. Piano lessons will help students be able to play piano by looking at the notations instead of looking at the keys. For a good pianist, this is going to be an important step and if one starts to learn that way right from start it will make things easier later. Understanding the notations and to be able to read them is important for any musician, especially if one wants to play classic tunes on their own without the need to remember them or have someone by their side.
Graceful fingers and a steady palm along with smooth reading of notations are required for one to be able to play piano and this is what most music schools strive to get their students up to. The piano instructors hence need to be good themselves to demonstrate the right approach and also have the ability to communicate well with the students.
