G2 Ciao
Gruppo Due · Massimiliano Audretsch

A conceptual display typeface by Massimiliano Audretsch in which cuts are named after vocal intonation properties rather than conventional weights, derived from a historical sketch by W. A. Dwiggins.
About
G2 Ciao grew from research into the visual representation of spoken intonation, with its name an acronym for the Italian phrase meaning 'perceiving intonation with your eyes'. Its letterforms trace back to a Dwiggins sketch likely intended as a technical draft for a typewriter head, built from precisely drawn outlines connected only by hairlines, with no repeating pattern between letters. The eighteen variants carry names such as Silent, Sharp, Strong and Swift, mapping auditory qualities onto typographic form rather than traditional weight or style distinctions.
Classification
The typeface defies conventional classification; its cuts are named after vocal intonation properties rather than weights, and its letterforms are derived from disconnected outlined elements joined by hairlines, placing it firmly in the experimental display category.
