Well, here's a rough "frequency chart" from memory. The range of good human hearing is from 20 Hz to 20kHz, broken down roughly as follows (others correct me if I err):
1. Bass range: usually defined as the bottom two octaves, from 20 - 80 Hz. The deepest part of the bass spectrum, from 16-30 Hz, is normally reproduced only by a large pipe organ. (The upright acoustic bass, for example, produces tones down to about 32 Hz.) Some audiophile charts also include definitions of mid-bass (80-120 Hz) and upper bass (120-160 Hz).
2. Lower mid-range: 160-320 Hz
3. Mid-range: 320 Hz up to about 1000 Hz
4. Upper mid-range: 1000 Hz up to about 2000 Hz
5. Lower treble: 2000 Hz up to about 4000 Hz
6. Mid-treble: 4000 Hz up to about 8-10,000 Hz
7. Upper treble: frequencies above the 8-10 kHz range
