Describe the characteristics of the Others in Portrait of a Musician's Identity of the sitter.
At the end of the 19th century, the subject of the portrait was identified by Paul Müller-Walde as Galeazzo Sanseverino, Ludovico's son-in-law and captain general of the Sforza militias, a prominent figure of the Milanese court. In support of this thesis, the Italian scholar Piero Misciatelli recalls that Galeazzo had been a patron of Leonardo and was probably passionate about music. Other scholars, such as the French art historian Robert de la Sizeranne, have recognized the traits of his father, Roberto Sanseverino.Gian Galeazzo Sforza (1469–1494) has been proposed, given that the original, vague, description of the portrait stated that it depicted the Duke of Milan. Syson has noted that this identification would be particularly meaningful, as Gian Galeazzo was the rightful heir to the throne before Ludovico took power. However, there is no direct evidence to support this, and the uncovering of the sheet music makes this very unlikely as Gian Galeazzo is not known to have been a musician.Francesco Canova da Milano (1497–1543), an Italian lutenist and composer, and the Flemish singer Giovanni Cordier have been proposed, albeit without substantive evidence.  The Dutch illustrator Siegfried Woldhek has suggested that the Portrait of a Musician is one of three self-portraits by Leonardo.
