Adami was born in Verona. He graduated at the University of Padua in Law but dedicated his career as a writer, theatre playwright, and then music critic. After the death of Puccini, Adami published a collection of the composer's letters in Epistolario (1928).

He wrote a second biography Il romanzo della vita di Giacomo Puccini ("The life of Giacomo Puccini") in 1942.
Adami also wrote librettos for other composers including Riccardo Zandonai's La via della finestra (1919); and Franco Vittadini's Anima allegra (1921) and Nazareth (1925). He was a music critic for La sera (Milan) and for the review La comedia from 1931 to 1934. Adami acted as publicist with the house of Ricordi to the end of his life. He died in Milan aged 67.
