After resigning from the Navy in 1894, he began to study harmony in Roubaix, first with Julien Koszul (grandfather of composer Henri Dutilleux), who encouraged him to pursue his formation in Paris with Eugène Gigout; Roussel then continued his studies until 1908 at the Schola Cantorum de Paris, where one of his teachers was Vincent d'Indy.
Roussel's training at the Schola Cantorum, with its emphasis on rigorous academic models such as Palestrina and Bach, left its mark on his mature style, which is characterized by contrapuntal textures.
On the whole Roussel's orchestration is rather heavy compared to the subtle and nuanced style of other French composers like Debussy or, indeed, Gabriel Fauré.
Roussel's most important works were the ballets Le festin de l'araignée, Bacchus et Ariane, and Aeneas and the four symphonies, of which the Third in G minor, and the Fourth in A major, are highly regarded and epitomize his mature neoclassical style.
The violin sonata, the trio, the Poème de la Forêt derived more or less directly from the Franckian school, the Festin de l'Araignée and the Evocations from Debussyan Impressionism; and yet the hand of Albert Roussel alone could have written this music, at once so subtle and so firmly fixed in its design... With Padmâvatî, the new Roussel begins to realize his possibilities and his individual technique... Then came works of perfect homogeneity and notable originality.
80 are the masterpieces which mark the last stage of this great artist.Arturo Toscanini included the suite from the ballet Le festin de l'araignée in one of his broadcast concerts with the NBC Symphony Orchestra.
One brief assessment of his career says:[5] Roussel will never attain the popularity of Debussy or Ravel, as his work lacks sensuous appeal....yet he was an important and compelling French composer.
The writing sets unrelated keys against one another but eventually seeks strong tonal centers; in other words, it can bark and growl but in the end wags its tail.
The collection contains many unique documents including a dozen musical manuscripts, autographs, around 250 letters (100 of them unpublished), a travel diary, recordings (including most of the early recordings of his compositions), iconography, a large collection of press clippings, programs and other documents linked to Roussel's works and life.
