A contemporary of Tomaso Albinoni, Marcello was the son of a senator in Venice. As such, he enjoyed a comfortable life that gave him the scope to pursue his interest in music. He held concerts in his hometown and also composed and published several sets of concertos, including six concertos under the title of La Cetra (The Lyre), as well as cantatas, arias, canzonets, and violin sonatas. Marcello, being a slightly older contemporary of Antonio Vivaldi, often composed under the pseudonym Eterio Stinfalico, his name as a member of the celebrated Arcadian Academy (Pontificia Accademia degli Arcadi). He died in Padua in 1747. 　　Alessandro's brother was Benedetto Marcello, also a composer, who illegally married his singing student Rosanna Scalfi in 1728. After his death she was unable to inherit his estate, and in 1742 she filed suit against Alessandro Marcello, seeking financial support.
