Musically, we achieve excitement and impact when establishing chords. In the use of a Triad, 3 notes can, in unison, provide a more impactful outcome. Rather than 3 notes across 3 movements that yield singular results, the Triad(chord) is a way of making a composite with low effort.
Similarly, examine the pulley and the lever. Nudging levers to activate a pull rather than pulling to produce is inefficient.
Our work is better served if always think of the low resistance, high impact levers….
