Musical sounds are created by vibrations that travel through the air and are perceived by our ears. These vibrations can come from various sources, such as musical instruments like guitars, pianos, and drums, or from the human voice. The pitch of a sound is determined by the frequency of the vibrations, while the volume is influenced by the amplitude. Different musical sounds can be combined to create melodies and harmonies. The organization of these sounds over time forms music, which can evoke emotions and convey messages. Genres like classical, jazz, and pop showcase the diversity of musical sounds and styles enjoyed by people worldwide.
