We are considering starting our son on the "Harmony Road Piano Course". He is 4 years old and seems to be very interested in music (we play often at home).

I noticed that a lot of children here who take lessons don't do it seriously and the standards are often very low, compared to what I am used to (I am from Russia).
So, if I want my son to have lessons, I would only want them to be serious, so that he actually learns propertly.

My question is, what are your thoughts on this Harmony Road course? This is the one used by our local music school.

Thank you very much!
