I start here a project with the complete "Essay théorique et pratique" of Guillaume Lasceux.
Excuse my for this first contribution. The serie should be complete: I want here to show how Lasceux opens organ students the aproach to the instrument. Lasceux rises up the level of musical quality and of technical difficulty very fast in his book with organ pieces. The "music" will come soon, but one, latest two uploads later.
For further informations about Guillaume Lasceux and his compendium, please, have a look to my essay Guillaume Lasceux and his Compendium "Essay théorique et pratique" on THE BARDE.
