Rigor is the art and practice of remaining fixed on a method or a way of doing things. In politics, it means staying on message. In art, it means adhering to the core principles of that art. In science it means disciplined adherence to scientific method, without taking shortcuts. In team sports, it means executing the game plan.
The essence of genius is the ability to contribute to the whole by departing from established methods: to see what no one else has seen and act on it. Yet it is the genius’ mastery of the discipline that allows her to see beyond it. For example, Einstein understood the prevailing theories in physics of his time but was able to see beyond, transcend and transform them. A person becomes a genius by rigorously mastering the discipline first.

Music: Composers, artists, and major works
Johann Sebastian Bach is widely regarded as history’s most rigorous composer. No one composed so tightly, and yet so freely and creatively as he did. Virtually all of his major works illustrate this point. I choose his orchestral suites and his French and English suites for keyboard to illustrate it here. French Suites, bwv 812-817, performed by:
- Christophe Rousset
- Bob van Asperen
- Pieter-Jan Belder
- Blandine Rannou
- Christopher Hogwood
- Glenn Gould (piano)
- Tatiana Nikolaeva (piano)
- Andras Schiff (piano)
English Suites, bwv 806-811, performed by:
