French organ builders at this time were very interested in colour (meaning: different sounds). Many stops had names like Cornet, Tierce and Prestant. When all the stops of the Principal chorus played together it was called the "Plein jeux". This was like the medieval Blockwerk. All the reed chorus together was called "Grand jeux". This would have sounded very loud and was used for dialogues and fugues. Composers included Nicolas de Grigny (1672-1703), Louis Marchand (1669-1732), Louis Nicolas Clérambault (1676-1749), Louis Claude Daquin (1694-1772) and François Couperin (1683-1733).
