“the sum of the parts is greater than the whole” if a group of individually talented people work together successfully “that teamwork will produce an overall better result than if each person” was trying to do their own thing. That’s a overtly mathematical explanation for a successful band. But with a successful band, you got your math and then you got your chemistry. The end result is an unpredictable outcome of the collision between math and chemistry…with a whole bunch of emotion in between. And when it works out, it’s a miracle.
