What types of symphonism did M. I. Glinka initiate?

M. I. Glinka is credited with initiating the genre of symphonism in Russian music. Symphonism is a style of composition that combines elements of symphonic music and opera. Glinka's symphonism was a fusion of Russian folk tunes, Italian bel canto vocal style, and Western European symphonic forms. Glinka's symphonism was characterized by a more lyrical, melodic style, with a focus on creating a unified musical structure. He used the operatic arias as the main melodic material, but also integrated elements of symphonic music such as fugues, canons, and a variety of textures. Glinka's symphonism was also distinguished by its use of harmonic progressions and modulations, as well as its use of orchestral color and texture. Glinka's symphonism was a major influence on later Russian composers, such as Tchaikovsky and Rimsky-Korsakov, who further developed the style.
