I was originally going to call this post "Good Vibrations", but decided against it.
Because that would be dorky.
Anyhoo, today we're going to take a look at a simple yet informative ear training primer put together by Jay Rose over at his website, dplay.com. In addition to being a working professional and writing a monthly column for DV Magazine, he has also authored some very useful audio textbooks, which you should buy and peruse over your morning Wheaties there, champ.
The primer starts out with a short audio montage, that then is repeated with very narrow band filtering ranges (ie: only low bass, then mid bass, then mid range, etc.). Most folks getting started may only know frequency response as low or high, bass or treble, but with tools like this demo, you can start to put a number to it. This is measured in Hertz, or cycles per second.

P.S. Those of you who have the time and the buckaroos to pursue a more in-depth ear-training regimen should check out Dave Moulton's Golden Ears, via moultonlabs.com.
