At the beginning of the school year, when I ask my choir to sing fortissimo, they give me a stack of one hundred $1 bills. Rich, substantial, powerful. And when they decrescendo to pianissimo, they simply take away ninety-nine of the bills. Weak, unsupported, lifeless.
Now I ask them to keep the fortissimo as twenty singles, but to make the pianissimo a $100 bill. The stack has less height (volume) but retains the same fiscal power (vocal energy). The end result is a vital, engaged sound across the dynamic spectrum.
