When holding a guitar or flute the elbow joint bends where?

When holding a guitar or Flute, the elbow joint typically bends to allow the instrument to be positioned comfortably for playing. For a guitar, the elbow bends outward as the arm rests on the body of the instrument, while for a flute, the elbow may bend slightly upward and outward to support the flute's position. In both cases, the bending is essential for facilitating ease of movement and proper technique.
