In 1914, Doret returned to Switzerland and began studying local popular music and folk music traditions.
He also wrote for Swiss newspapers and wrote a memoir, Temps et contretemps, published in 1942.
Most of his output was vocal, and included operas, music theatre pieces, one oratorio, choral music, and more than 300 songs.
His only instrumental works were two orchestral pieces, a string quartet, and a piano quintet.
Doret died 1943 in Lausanne.
