However, Lupi's most widely heard piece was his Armonie del pianeta Saturno [it] for oboe (or, sometimes, trumpet), harp and strings which was played each night from 1954 to 1986 at the close of RAI television transmissions.
[1] He held the chair in composition at the Florence Conservatory from 1941 until his death and published three books on music theory, the last of them posthumously.
From the 1950s his theoretical approach and his compositions, especially his stage works, were strongly influenced by the ideas of Rudolf Steiner.
While his father was away in World War I, the family moved to back to Guastalla where Lupi began his music studies at the age of 8.
He received diplomas in piano (1927) and cello (1928) before he began his study of composition under Arrigo Pedrollo, graduating from the conservatory in 1934.
