Our writing equipment takes part in the forming of our thoughts.
— Friedrich Nietzsche
Musical performance is, in every case, a bodying forth of energy. Though it might rely on electrical or electronic means, it is, at bottom, a physical act. We do it with our hands, our limbs, our voices — at some point or other, we bring the sound into existence.
Though taken out of context (he was talking about working on a typewriter as opposed to writing everything out longhand), I think Nietzsche’s remark describes the condition under which music is played.
For example, I play a drum kit, not hand percussion or any other percussion instruments. I have at my usual disposal a snare drum, a kick drum, two rack toms, a hi-hat, two crash cymbals, and two ride cymbals. I strike these items with sticks, except for the hi-hat and kick, which are pedal-driven (or both struck and pedal-driven in the hi-hat’s case).
All the noises I make are derived from a combination of my body and the preceding array. Therefore, I can, within the limits of my mind, strength, and dexterity, strike any combination of these items simultaneously or in succession, in any order, at any volume. On the other hand, I can refrain from striking any or all of them as I see fit. The subsequent fitness results from my choices.
Those choices are guided by the energy at my disposal, from my personal fitness, the sounds of my drum kit, and the fitness and sounds of my collaborators. Collectively, the energy will be, by definition, greater than its contributing parts. If we are to remain humble and effective in the face of music, we must keep this result in mind at all times: no single collaborative expression is more important than any other.
