It is one word, and it has changed
the concept of music education:

Colourstrings
Colourstrings has an excellent reputation worldwide for providing quality music education
for children, in an intuitive and enjoyable way,
from music kindergarten to conservatoire level.
There is a huge demand for 
Colourstrings-trained teachers for instrumental teaching and music kindergarten in state schools, public schools and in private teaching.
So many teachers tell us that when applying
for a job, a frequently asked question is,
“Do you have any Colourstrings training?”
