The Execution Gap

About Thomas Hornig — Professor, Author

About the Author

Thomas William Hornig has taught at the Lebanese National Higher Conservatory of Music since 1994, where he is professor of saxophone and principal saxophonist. He is the author of The Execution Gap (second edition, 2026), a study of the distance between what law mandates and what institutions actually deliver — and of how legal personhood decides whose rights attach.

The book is built on a documented case: his own three decades inside Lebanon’s public sector, the primary records of which are published on this site. Alongside the book he developed the Personhood Attachment Index, a diagnostic for measuring how firmly rights attach to a person, and the Personhood Prism app, which applies it. He also builds practice software for wind players, including The Whole Horn. He lives and works in Beirut.

The Book

The execution gap is the structural distance between what the law mandates and what institutions actually deliver. It is not a malfunction. It is the mechanism. The second edition (2026) sets out the framework, the diagnostic, and the case record behind it.

Career and Contributions

Hornig joined the Lebanese National Higher Conservatory of Music as a saxophone professor in 1994 and has taught there for more than three decades, building its saxophone program and performing as principal saxophonist. His experience navigating the intersection of labor law, foreign-worker rights, and institutional power led him to develop the execution gap framework.

Three Theoretical Contributions

His book The Execution Gap (second edition, 2026) presents three theoretical contributions:

  • The Personhood Master Key Theory (PMKT) — legal personhood as the master variable controlling rights distribution
  • The Personhood Attachment Index (PAI) — a quantitative diagnostic for measuring rights attachment
  • The EA-30-60-90 Framework — a severity classification system for execution gaps

The Throat-First Saxophone Method

In music education, Hornig developed the Throat-First method, a saxophone pedagogy that starts from throat position and voicing rather than from embouchure alone. Informed by MRI studies of the vocal tract, it uses the E-Position voicing technique and the Two-Subsystem Tongue Model to teach control of the vocal tract during play. Its exercises run through his practice software for wind players, including The Whole Horn.
