In my essay about sound, I am going to explain how different forms of sound are created, how they are heard, what a frequency is, how certain vibrations can decide the pitch, loudness and frequency of a sound wave. I am also going to explain how music is created, how every note has a different frequency, that harmony is very important when making music. I am also going to tell you about sound recording, replaying music, analogue and digital, microphones and loudspeakers.
By "plucking" a violin string, you enable the strings to vibrate very quickly and you automatically hear a sound. This happens because the air carries the vibrations made by the violin strings into your ear. Once inside your ear, the vibrations are immediately become electrical signals that are then sent to your brain. Sound waves are also vibrations that pass from one set of particles to the next.
