In the context of Portrait of a Musician, discuss the Composition of the Description.
This painting was executed in oils and perhaps tempera on a small, 44.7 cm × 32 cm (17.6 in × 12.6 in) walnut wood panel. It depicts a young man in bust length and three-quarter view, whose right hand holds a folded piece of sheet music. The painting is largely unfinished save for the face and hair, but is in good condition overall, with only the bottom right corner suffering damage. The art historian Kenneth Clark noted that out of Leonardo's surviving works, the Musician is perhaps the best preserved, despite the fading of colors over time.The bottom of the work may have been slightly trimmed. There is a small amount of retouching, especially towards the back of the head; the art historian Frank Zöllner has noted that this retouching introduced the somewhat unsuccessful shading of the neck and the left side of the lips. With its black background, the portrait is reminiscent of Leonardo's later portraits, the Lady with an Ermine and La Belle Ferronnière, but differs from them in that the sitter's body and head face the same direction. The biographer Walter Isaacson has noted that due to the work's unfinished state, the portrait's shadows are overtly harsh, and the portrait itself features fewer of the thin layers of oil paint typically found in Leonardo's paintings.
