Thanks to Randy Masters for collecting some of these frequencies

 

Frequency Ranges in Music
 
( From a recording engineering perspective )

LOW BASS  -  < 40 Hertz
 
This range is sometimes called the “ sub-bass. ”  It is commonly found in Rap Booms and the low bass of Kick Drums and Bass Guitars.  It is difficult for many people to discern pitch very well at this range.  This range is often used in movies for earthquakes, rumble, and explosions.

BASS  -  40 - 100 Hertz
40 - 60 hertz is the approximate range that is boosted when you turn up the “bass” tone control on a stereo.

MUDD ( OOOHZONE )  -  100 - 800 Hertz ( particularly around 100-400 )
 
This range is called the oohzone ( pronounced “ ooh ” as in “ boo ” ) because if you boost this range it makes you say “ewwwwh” with disgust.  This range is also referred to as the “oohzone” because if you put your hand on your chest and say “oooooooooohhhh”, you notice that this frequency resonates your chest cavity.  This means that your chest cavity is boosting the volume of this frequency range.  When frequencies are boosted too much in this range, they sound extremely muddy and unclear, and can even cause extreme fatigue when not evened out.
