One book:
Robert Sternberg - Handbook of Creativity
'Cheez' has summed it up well with his comments regarding teaching children. Yes, sometimes it can seem a little forced, but, if given complete freedom, would the child want to learn anything that we could consider abstract? e.g. would it naturally want to learn how to read?
Bad tuition is also a major issue. But the quantity of tuition, i feel, is also important, and an issue that has been overlooked here. I had a lesson every day from the age of 3 to the age of 16 (well, maybe not christmas day
), and i feel it has made a great difference.
I have a pupil just now who i teach every day (well, 5 days a week) - she is 6 and 1/2, and has just gained a distinction in grade 5 (ABRSM). (She has been getting lessons for 3 years now). I'd say this approach makes a difference - i see it with pupils i have who get a lesson once a week. The gulf becomes huge, even after a few months.
(Or, in another way - if the child had a reading lesson once a week, how good would the child be at reading by the age of 18? So it is with music.)
But i do understand that the cost of such an approach is a huge issue. I only have 2 pupils i teach in this way, and the rest i see once a week. However, i'd rather only have 4 pupils who i saw every day. My energies (and the pupils) would be better spent this way.
I'd say in order to develop fully in the individual, music needs to stop being considered 'extra-curricular' and needs to be something that is integral to the daily life of the individual.
It would be interesting to hear some thoughts on this.
