lessons, you will want to make sure that you are able to find the perfect teacher. When you choose the right piano teacher, your children will be more inclined to stick with the lessons and enjoy learning to play piano.
Just because someone can play the piano doesn’t mean that they are going to be able to successfully teach piano. When choosing your teacher, make sure that the teacher is going to be able to communicate well with the piano student, communication is going to be a very important factor with piano lessons just as it is with so many other things. You also want to make sure that the piano teacher is the motivating type, you need to be sure that the teacher will be able to keep the student interested in the piano at all times. The piano teacher should also be able to teach the student about the fundamental building blocks of music such as harmony and theory.
To help narrow down your search for a quality teacher, you might ask if the student can experience a sample lesson or two. This will allow the student to spend a session or two with the teacher to see if the student understands the teachers way of teaching. It will also allow the student to see if there is a good communication level between herself and the teacher. This will be a good point at which the student can find out the teacher teachers expectations of him.
Check the references of the piano teacher that you are considering. You should have no problem asking the students that have studied piano under the teacher what their review of the teacher is. You might ask if the teacher is patient, is a good communicator and if she teaches at a level that a beginning student will be able to benefit from. You can even ask point blank if they enjoy taking piano lessons from the teacher, do they look forward to their next lesson or do they dread having to go to their next lesson.
Interview the teacher that you are considering, this will help you learn which books she chooses to teach from as well as the method that she teaches piano. You can also get insight to her expectations on practice and recitals during an interview. 
One of the qualities to look for in a piano teacher is that she enjoys giving lessons. You want to make sure that she is going to find as much enjoyment in giving the lessons that the student will find in taking the lessons.
You might choose to attend one of the recitals that the music teacher is giving to help you see first hand just how the teachers conducts herself.
