Invention IV is a continuation, perhaps a systematization, of the development already proposed in my previous inventions, in particular the third, toward a sort of entirely personal neo-modalism that favours a writing style with a more supple use of legato, greater harmonic openness and a more improvised construction. This approach is loosely assembled around a type of refrain that is characterized by a specific “rhythmic theme”. Perhaps in contrast with works written when I was younger (notably the 7 Bagatelles), I decided to favour the symphonic organ's colourful and iridescent sonorities, such as those produced by Cavaillé-Coll's large instruments.
This piece is dedicated to the organist Liesbeth Schlumberger, whom I thank for the pertinence and scope of her advice, and also to Thomas Lacôte, notably regarding registration.
