# The Dictionnaire de musique is printed as a public technical vocabulary for a trade

Date: 1768

## The fact

In 1768 Rousseau’s Dictionnaire de musique appeared, a completed reference book for a skilled urban trade. It is industrial-cultural policy by a private author, not a ministry.

## Context

A music dictionary is knowledge infrastructure for performers and copyists. High confidence on the imprint.

[Jean-Jacques Rousseau](/people/jean-jacques-rousseau) is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.

## Evidence and sources

Official library, encyclopedia, or public-domain edition pages and an independent publisher independently describe this instrument.

Official or archival record: Gallica — Rousseau printed works (https://gallica.bnf.fr/; Bibliothèque nationale de France).

## Significance

A 1768 music dictionary is not Émile and not a conservatoire statute.

A 1768 music dictionary is not Émile and not a conservatoire statute.

## What is established and what is not

Established as a dated public record of this instrument.

What would change the picture: a contradictory original with a different date or name, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.
