How Geoff Castellucci uses that range
Castellucci builds his sound on subharmonic and fry blends: near B0 he lets the folds beat at half rate, keeping the jaw loose so the pitch reads lower than the effort. His speaking-level mix carries to about E4 before he hands off to a bright, character-driven falsetto up to Bb5. Onsets are playful and percussive — he treats consonants as rhythm. The trap for imitators is muscling the low notes with pressed compression; his lows are quiet at the source and loud in the mic. Close-mic craft, relaxed larynx, exaggerated diction: that is the engine.
