Tumbum livre

The umbum is characterized by a large gravity concentration in a spherical form that connects the ends of the instrument. Gravity is the universal constant in the interaction between mouth and mouth or mouth and ear.

Phonosophia is an offshoot project of the Earth Anatomical Theater. Phonosophia draws relations between the voice and transmission. These objects and drawings depart from the three aspects of the Earth Anatomical Theater: gravity (Earth), ear and voice (anatomy and physiology) and brass instruments and drums (theater).
