Final answer:
In Shakespeare's plays, music was often used to convey emotions and set the mood, with a prime example being the opening scene of 'Twelfth Night' where Duke Orsino's lines demonstrate the integration of musical elements in his work.
Step-by-step explanation:
Shakespeare often incorporated music into his plays as a powerful means of expression and to enhance the theatrical experience. An obvious scene where music would be used in a Shakespearian play is the opening of Twelfth Night, where the character Duke Orsino famously declares 'If music be the food of love, play on.' This reflects the mood of the character and sets the tone for the rest of the play, as well as highlighting the Renaissance literary ideal of blending theatrical performance with eloquent, musical language.
