The creative activities of the National Music School are more prosperous. Among them, the research on black music and the tendency to seek creative sources in black music are particularly high; thus, a "Cuban-Africanism" creative trend has been formed among professional composers. The representative figures are A. Roldan and A.G. Catulla. They widely used the rhythm and percussion instruments of Cuban-African music in symphonic music works. Their unique style and novel techniques paved the way for the development of Cuban symphony. Such as Roldan's "Rhythm" (six pieces, two of which are all played with Cuban percussion instruments); Catulla's "Bembe" written for an ensemble of 14 instruments, etc., with intricate rhythmic progression and modernism. The harmonic characteristics show the rich colors of Cuban national music. In addition, E. Lecuona's (1896-1963) "Black Rhapsody" and the song "Sibonne" have become famous pieces spread abroad.

The creative activities of the famous Cuban writer, musicologist and critic A. Carpentier and the music educator J. Adewole have a great influence on the construction and development of Cuban music theory. They are the authors of "Cuban Music" and "Introduction to Cuban Music" respectively.
