Because many musical notes fall outside this range. For example, the strings that create the note middle C on a piano keyboard vibrate at just 261 Hz. There are many base notes lower than that - and lots of treble notes that are higher than 4,000 Hz.
Bass amplifiers are used to amplify the music that comes from a bass guitar. The average frequency range for bass amplifiers is between 25 and 250 watts.

amplitude modulation & frequency modulation
Pitch is a frequency and is measured in Hertz. A common tuning pitch is A440; 440 refers to the frequency of the pitch.
The frequency with which the carrier frequency is deviated is exactly the modulating frequency, i.e. the frequency of the sound that makes up the music or voice announcement, stereo pilot, SCA subcarrier, etc.
To expand on LincMad's statement: The frequency range of a voice-grade telephone circuit is 300 to 3100 Hertz. The frequency range of your stereo is 20 to 20,000 Hertz. They use the narrower bandwidth on a phone system so they can pack more phone calls into the same cable.A telephone transmits only a very limited range of audio frequencies, optimized for speech. Thus, all the high and low notes in music get lost over a telephone connection.

They can, if you hook them to external speakers, or an FM transmitting device.
Pitch - In music, the higher or lower the pitch, the higher or lower the note. Pitch is determined by the frequency of the sound waves.

You plug the device into your iPod, and it will then transmit your music on a certain radio frequency. You can then tune a radio into this specific frequency, and you will be able to listen to your music.
Music are vibrations, these vibrations synchronize with our neural brainwaves. Not just reggae, but any music with the right timing between beats and music will calm us down. Most of reggae's beats are almost the same frequency of calm heartbeat, thus the calmness.
As a form of entertainment- much as it is still used today. Music was also used as a method of transmitting and retaining tales, such as Breton Lais. These could either be recited by writ, or to music.
If you're transmitting sound waves whether or not they're causing damage or inconvenience to someone or something, of course you're responsible because YOU'RE transmitting them.
amplitude modulation & frequency modulation
If you're talking "music", you could possible call it pitch. Each note (pitch) has a specific frequency.
Pitch is a frequency and is measured in Hertz. A common tuning pitch is A440; 440 refers to the frequency of the pitch.
