Depending on the guitar sound driving it and the reso- nance of each player's mouth, should have great "bite" around 1200Hz and dies above 6kHz.
Cymbal overhead
About the same as hi-hat only has more low end around 150Hz.
Hi Hat
Watch for the "gong" sound around 300Hz. Good "shimmer" sounds are around 8kHz to 10kHz.
Floor Tom
Same as tom, but extends down to 80Hz.
Tom Tom
The main fullness is around 200Hz. The mid punch extends to 4kHz.
Snare drum
Good fullness at 100Hz. The "crack" is boosted at 2kHz. real easy. The snares extend to above 4kHz.
Bass drum
Great low "kick" at 40Hz. The mids at 2kHz gives the familiar "punch".
Brass instruments
Watch for "hot" mids around 2kHz. Low end boost around 400Hz. Top end clarity at 6kHz.
Violin
Richfullness at 400Hz. Natural mids around 1500 to 2500Hz. Avoid "scratch" sounds at 8kHz.
Organ
Usually dies under 200Hz. Has great mid-sounds around 1200 to 2000Hz. Top end cuts off at 6kHz.
Piano (Electric)
Good mid-clarity at 3kHz to 5kHz thins out rapidly in high end. Be careful around 1.5kHz to 2.5kHz to avoid the "bar room sound".
Piano (Acoustic)
Bass strings responate around 100Hz. Watch for sub- harmonics at 30 to 50Hz.
Human voice
Good fullness at 150Hz. Watch for "boominess" around 250Hz. Mid-range 10kHz.
Bass guitar
Extreme lows are at 60 to 90Hz. "Pick" or "pluck" sounds are around 800 to 1200Hz. Upper harmonics clarified about 3kHz.
Electric guitar
Resonances differ — depending on type. Good full sounds around 300 to 500Hz. Clarity at 3kHz.
INSTRUMENT EQUALIZATION CHART
Acoustic guitar Bass strings resonate between 70 to 120Hz, body around 300Hz. Avoid boosting these to stop feedback. 3kHz and 5kHz gives great "clarity".
Figure 1
Probably the most im- portant of all. Most all instruments contain har- monics here.
300Hz boosting can cause horn like sounds. 1k to 2k sounds tinny. Too much here sounds like the tele- phone.

Applications

Equalization for music

The Graphic Equalizer is designed not only for use in preventing feedback and equalizing uneven room frequency response to be flat, but also for equalizing frequency response to your tastes and producing favourable sound for you. Fig. 1 shows each frequency band and its corresponding auditory feeling. Fig. 2 and table 1 show the relation between each musical instrument and its frequency band. They can be of great help in the equalizer operation. (They are referenced from a book entitled "Practical Guide for concert")
