Hi DespeRuth, Pianoforte and Star,
Tks so much for your replies and advice. It's been more than 1 year since my posting of the enquiry. Seldom login into SIngapore Expat since then as I have been trying hard to prepare my Grade 8 Practical Exam.
It's really a painful experience to manage my time for the full-time job, family and piano practice. Thank God that I have passed the practical exam and would like to share my joy with you.
I have looked up for recent info in Yamaha and Christofori Music school as suggested, only to find that Yamaha has no longer held the cert of piano teaching course for two years; while Christofori only offers training for full-time teachers.
I am now trying to look out for similar courses and meanwhile I'm preparing the Grade 8 Theory Exam. Good luck to me and just let me know if you have further advices for me.
Wish you all a Merry Christmas!
