My daughter joined the course for about 3 months. They talked 'drmfs..' not "cdefgab". It is not only a piano course. It is train the listening and singing but not to train to see stave. I think to learn 1 year and then have personal training on piano at the same time in the year 2.
My son has attended course for 9 months. Overall it is a good basic music course for children however it will give parents pressure if your child could not keep up with the teachers' speed of teaching.
The big disadvantage is that they dont have make up class for students if they miss the class (no matter what reasons they only provide make up class if the teacher is not available!) the course fee is pretty expensive so I prefer private piano lesson for my son. He has been attending the piano class taught by a piano teacher since Jan now he can read the notes in C & G majors and play by both hands some simple songs, more importantly he enjoys it very much playing piano!!!
