Grammar of Music
Music
Learn, practise and discuss music theory in English or Portuguese: an encyclopedia, interactive tools, ear training, courses with spaced repetition and a tutor that explains every answer.
Tech lead, software engineer and trained conductor.
I’m Filipe Fonseca, a tech lead at SuperSim in São Paulo, Brazil. I trained and worked as a conductor at the University of São Paulo before moving into software, and today I build music software of my own: Grammar of Music, Virtual Choir and Sheet Music Stores.
Virtual Choir Creator
Music · 2020
Each singer records their part at home over a guide track; the app synchronises the takes and renders the whole choir as a single grid video.
Sheet Music Stores
Music · 2021
Find a piece and compare its sheet music editions, arrangements and prices across the stores that sell it.
Wayfinder
Productivity · 2026
A life-planning companion: values, mission, vision, goals and habits across eight areas of life, revisited in daily, weekly, quarterly and annual sessions.
