From Donard de Cogan
Although there is perfect pitch in our family, my son did not inherit it.
However, as a chorister in Norwich Cathedral he was taught a very simple trick
to overcome this problem.
Choristers were trained to locate their vocal “break”—the transition
point from a note sounded in the chest to what is called a “head note”. Once
this was mastered, the boys could either identify sounds relative to this or
could accurately pitch a printed note by singing from their break.
