Expressive sounds refer to vocal or instrumental sounds that convey emotions or feelings. These sounds can be found in various forms of music, speech, and nature. For example, a violin can produce a range of expressive sounds, from joyful melodies to sorrowful notes, depending on how it is played. In addition to music, expressive sounds are also present in everyday life, such as laughter, crying, or even the rustling of leaves. These sounds can communicate a wide array of emotions and reactions, making them an essential part of human and animal interactions.
