Eduardo Sabat Garibaldi was a chemist and the inventor of an instrument he called the dinarra, a microtonal guitar, whose name is a portmanteu blending "dynamics" with "guitar". In his 1994 book "Principles of Dynamic Range" he discusses the theory and practice of the instrument. The 7-limit garibaldi temperament is named for him, but the 1/9-schisma tuning he advocated made his dinarra tuning optimized more for pontiac, with a tuning close to that of 171edo, so that it would actually possess numerous tetrads of pontiac temperament.

He was president of the Inventors' Association of Uruguay.
