Long story up ahead...
When I was about 7, I started private lessons with a distant relative in Singapore. When I saw my uncle playing all the different pieces when I was older, I just was captured by the beauty of the music so my uncle brought me to a music store with my mom and we bought a couple of those books. When I took those book to my teacher and told her I wanted to learn a couple of pieces by J.S Bach, Handel, Haydn, Debussy...and so on. She was just like "these pieces are too hard for you and you can't learn them"....I got so upset that I never asked her to let me learn anything in particular ever again. At that point I was already Grade 5 ABRSM. The only major composers' pieces I ever played was Handel, Mozart, Beethoven, Clementi, Kulah...that's about it.
On the other hand when I moved to canada about 3& a half years ago, I carried on with a famous concert pianist and teacher, she even auditioned me as she had other students she could take. I played Fur Elise for her and she was simply enchanted by my playing, musical sense and talent so she took me as her student. At that time 2 of my cousins were under her. After I started, she reworked my entire technique except appegios which she declared excellent. I carried on with ABRSM and then decided to switch after a year. When I started grade 10 RCM, she pulled out the syllubus book and she looked at me and asked me which composers I liked...I just shrugged my shoulders the only composer I mentioned was Mozart, I told her what my previous teacher had said and she was appalled. However now, i'm perfectly happy. I've learnt many other composer's works by now...still yet to learn a few of them like Liszt.
If any of you have the same kind of teacher as I did in singapore, I would advice you to go and find a new one.
