thirtypence - totally agree.
I hate the way some teachers teach for the exam and don?t take time for a holistic approach to the tuition. Learning an instrument is different from learning an exam syllabus! I used to find it so frustrating when peris would lurch from one group of 3 pieces, exam, then next three pieces. Never any real exploration of genre, style, technique, musicality, etc etc etc to turn the child into a knowledgeable and able musician.
Some kids "know" x, y, z, scales are at grade 5+ and have no concept of the relationships between keys, how and why they are linked, chord progressions etc etc. Astonishing. Inability to sight read easily is a dead giveaway too. Same with aural tests. If they can?t "hear" the concepts in their heads and understand at a simple level, then the music is just robotic repetition and stops being "music" and creativity.
I think exams are a brilliant way to support and accent a learning curve BUT should act more like discreet scaffolding rather than the main building blocks of the progress. If your child is having lessons and they never step away from the syllabus and are never given any different pieces other than the syllabus pieces, I would talk to the teacher and question them about their teaching style.
