Aged 8, I was taken to the Ballet, because my Mum was a Dancer. The front row seats were meant to help me see the Dancers, but the Pit was all I saw. The Bassist played the whole concert right at me. This inspired me to become a Bassist, but seeing the whole orchestra, inspired me to become a Multi-Instrumentalist.
Motivation in learning has a great deal to do with feedback. Child will freely paint a picture and are encouraged to do so, from a young age. Few children Compose Music.
A painting gives instant feedback. The Artist can instantly see what they have created and Parents willingly mount the painting on the fridge door, with no assumption that it should be "perfect" - although I teach that "perfect" has more to do with wholeness than rightness. Could the same be said for the Composition of Music? Do we get the same feedback?
When we paint, we see what we have created. In Music, we are often too close to the Performance, to be able to hear what the audience hears.
