Description

Here we go with a lesson in electronics!! A filter is a piece of electronics that blocks frequencies, and a low-pass filter is a filter that blocks high frequencies above a certain frequency (i.e. it lets low frequencies pass). The frequency at which the filter operates is called the cut-off frequency. So in a low-pass filter, all the frequencies above the cut-off frequency are cut off or filtered. Still with me? Okay - so when we do a 909 Snare Drum filter sweep, we are imagining that the 909 snare drum is being put through a low-pass filter and the cut-off frequency is being swept upwards. This means that as time moves on, more and more frequencies are allowed through and the sound goes from being dull to bright. Get it? No?? Oh well, let's just make the sound...

Method

Start off by making a series of 909 snare sounds - easy.
Right, now start off with your mouth as if you are saying 'oooo' whilst you make the 909 snare.
Now whilst making the snare sounds, move your mouth so it goes from 'oooo' gadually to 'eeee'.
You should find that the 909 snare sounds go from being dull to bright.
