In this work, Leyster captures a solitary moment in which a young boy delicately plays a flute. He looks up and out of the frame, as if lost in concentration, or perhaps in the beautiful music itself. The precise placement of his fingers suggests a musician completely at ease with his instrument. At the same time, the composition of the painting is slightly unusual: against this plain interior, Leyster includes a violin and a recorder awkwardly displayed on the wall. The boy's posture is also slightly strange, as he leans back against what looks like a damaged chair. The boy's dreamy gaze suggests the power of music to transport the listener, a power not unlike the power of art.
There are many similarities between painting and music that run throughout Leyster's career. Art critic Peter Schjeldahl comments particularly on her virtuosic use of color here: "The work's finely modulated browns and grays are breathtaking. They affect like essences of the flute's sound - you practically hear them."
