Music typically has a regular, repeating pattern. This pattern is often created by the repetition of a melody, rhythm, or chord progression. The regularity of the pattern creates a sense of order and predictability.
Noise, on the other hand, is typically characterized by its lack of a regular pattern. The sound waves of noise are often irregular and unpredictable, which creates a sense of chaos and disorder.
Another difference between music and noise is the presence of harmonics. Harmonics are additional frequencies that accompany the main frequency of a sound wave. Music often contains harmonics, which give it a richer and more complex sound. Noise, on the other hand, typically does not contain as many harmonics, which gives it a more flat and dull sound.
Finally, music and noise can be distinguished by their emotional impact. Music often has the ability to evoke emotions, such as happiness, sadness, or excitement. Noise, on the other hand, is often associated with negative emotions, such as annoyance, stress, or anxiety.
Of course, there are some exceptions to these general rules. Some types of music can be dissonant and unpredictable, while some types of noise can be rhythmic and pleasant. However, in general, music and noise can be distinguished by their different shapes and patterns.
