When putting together a mix, it is handy to have knowledge of your sound sources and the frequencies generated by each. This article is intended to be a quick reference (with a table) to frequency bandwidths of various music sources.
Drums
Starting with the traditional left side of the console, drums are usually tuned to resonance from about 160Hz to 800Hz. But the total bandwidth of each drum can range from two octaves below to batter head sounds (click) into the presence bands (2 to 8KHz). For example, a 22-inch kick drum batter head is typically tuned to E3 or 164Hz. But sub-harmonics are given off at 82Hz and 41Hz, with these becoming the chest "thump" that should felt more than heard. And with the second harmonic suppressed (328Hz) to make room for other instruments, all that is left is the "click" around 3KHz Other drums are typically tuned a bit higher, like a 16-inch floor tom resonance at C4 (261Hz), 14-inch floor tom at F4 (349Hz), 12-inch rack tom at A4 (440Hz), 10-inch rack tom at D5 (587Hz) and a snare at G5 (783Hz). If you set drum gates, then the first suboctave below the batter head resonance is usually where the frequency band is set. From the above example for drum tunings, the kick is at 82Hz, 16-inch floor tom at 130Hz, 14-inch floor tom at 175Hz, 12-inch rack tom at 220Hz, 10-inch rack tom at 293Hz and snare at 366Hz.
