The Victory of Strength over Power
Edi Bilimoria – the U.K.
What is the subtle distinction between strength and power? In science we use the term energy rather than strength, energy being what one delivers, and power being the rate at which it is delivered. So for example, even a weak system that expends its energy at a high rate would be powerful. One case in point would be a cat expending a sudden burst of energy springing on a mouse. By contrast a high energy system expending energy slowly would be considered less powerful; for example a bulldog slowly lumbering towards his meal.
In the psychological realm, music beautifully illustrates the difference between power and energy – let’s now use the term strength. This is because music and life mirror one another. In his 2006 Reith lectures, the legendary pianist and conductor Daniel Barenboim explained how music expresses the ineffable dimension of life; and the hidden side of life is reflected in music. Barenboim also illustrated the difference between power and strength in a graphic way. Using the example of an orchestra, if the most dominant section – the brass (trumpets, trombones, etc.) – blare away unconcerned about the other instruments, the resulting orchestral sound would have brutal power, but no strength. Conversely when each instrument listens to its neighbours, harmonizing and blending (not subduing) its contribution to the greater orchestral whole, the sound would have real strength and for that matter, a power based on strength.
