Toni Mazzotti is a Brazilian multimedia artist and music theorist dedicated to studying new paradigms in rhythm and tuning. He has made an important contribution to popularizing 432 Hz as the most natural central reference point for the human voice and hearing.

Since 2000, he has studied music theory, history, technology, and related sciences. He proposes an enhancement of traditional theory by associating specific frequencies with musical notes, drawing connections between geometry, mathematics, cosmology, and music. A framework he calls Absolute Harmony.

In 2026, Toni presented his tuning proposal, which decompresses the spiral of fifths across the 12 octaves of the rhythmic and melodic spectrum. (Coming soon).

In 2018, he released the documentary 432 Activists on YouTube. In 2021, he documented Robert Edward Grant’s Precise Temperament Tuning.

He is the son of renowned Brazilian musicians who pioneered the independent vinyl scene in the country (see Ana Mazzotti). He was a DJ and a pioneer of the electronic music scene in Ceará, a music technology columnist for newspapers, and a radio station podcast host (see Cenacara.DJ).

Since 2010, he has been an activist for the decriminalization of shamanic substances, having helped include Brazil in the clinical trials that paved the way for the legalization of psychedelic therapy with this video.

Until 2018, his main work was helping brands, media, artists, and activists bring ideas to life through multimedia communication. Over the years, he has gained extensive experience in musical composition, soundtracks, sound design, mixing, mastering, video editing, animation, design, and scriptwriting. (see pieces broadcasted).
