Why does Handel set the words "dash them" to a large downward leap? to introduce a melody that contrasts with the beginning of the aria to provide a comparison with the declamatory style of the recitative to introduce the tone of Ritornello 2 to suggest an object being thrown from a great height

Handel’s decision to set "dash them" to a large downward leap is both dramatic and symbolic, aiming to emphasize the forceful action being described. In the context of the aria, this musical gesture captures the violent imagery of the words, making the audience feel the intensity of the emotion being conveyed. It's a masterful way to bridge text and music, allowing the listener to visualize the action through sound. Additionally, this musical technique creates a stark contrast with the more melodic elements that precede it, underscoring the shift from a more lyrical to a more aggressive expression. By using a downward leap, Handel indicates a jarring movement that aligns with the text's assertive directive, enhancing the overall narrative of the piece.
