The love that he developed for the Puerto Rican Danzas came about at a young age because of the influence which he received from his musically inclined family.
[1] Upon finishing his musical instruction, Alers went to play for various national and international bands and Symphony Orchestras.
Eventually, he formed his own band and recorded the Puerto Rican danzas composed by Juan Morel Campos, Manuel Gregorio Tavárez and Ángel Mislan.
In 1933, Alers was the conductor of Carmelo Díaz Soler's Orchestra, which had a daily segment in a radio program.
Alers took charge of the orchestra upon the death of Díaz Soler and in 1935 he felt the inspiration to compose a danza.
