Pablo Luna received his first lessons in music theory from an organist at a church in his birthplace, Alhama de Aragón.
His father, Pablo Luna Ferrer, who was a member of the Civil Guard, had moved with his family to the valley of the Ebro.
As a violinist, Luna would make money in hotels, cafes, churches and a small chamber orchestra, as well as in theaters.
He also knew the librettist Luis Pascual Frutos, who wrote the libretto for the operetta Mussetta, which premiered successfully in 1908.
In 1918, he released one of his greatest works, El niño Judío (The Jewish Boy), an exponent of the new style full of exoticism and sophistication.
