This is my personal e-mail adress, I only ask my daughter sometimes to translate my letters to Japanese, so that it is easier for You to understand. For Your questions my answers are the following:
1. Only students who already have learned solfeggio (music theory) in advance can be taught officially in a music school.
2. As the child does not frequent any school yet, he cannot be taught officially in a music school.
3. All official students at the music school have to frequent solfeggio lesson 45 minutes 2 times a week besides the violin lessons, which last 30 minutes (2 times a week).
4. The solfeggio lessons are held in groups and in Hungarian language.
5. I have talked to the headteacher; Your son Ko can take a private exam at the end of the schoolyear in violin so he receives a certificate about his violin studies.
6. One private lesson (30 minutes) costs 3000 HUF.
7. As I am not teaching Your son in his native language, I would ask for 3 months term of probation to see if we can work well together.
Tuesday I'm attending Ko at the music school at 14:00.
I would be delighted to see Akane at the concert of my students at 25th May, 15:00 at the music school.
Thank You for asking Your questions, I am looking forward to meeting Ko soon.
Yours sincerely:
