The Drop

The "drop" is what makes each fundamentally dubstep song so exhilarating.  It is the climax of the song, sometimes occurring more than once throughout the course of the song.  When breaking down this pivotal "drop", one can see that there are only a few contributors to its success.  These include: the wobble (as discussed in The Wobble), the intensifying of the rhythmic percussion (as discussed in Rhythm) and, most importantly, the drop of the bass.

The drop gets its name from a quote by one of dubstep's finest, Skrillex.  He famously says, "Drop the bass!" It's heard in his hit remix of Cinema.  The official video is below.

This song provides a wonderful example of the elements of the drop, each working together to create the final result.  The element not yet discussed on previous pages is the drop itself.  It is, in fact, an actual drop of the bass tone by up to an octave or more than the bass track used in the intro or outro portions of the song.  

Sub-bass

Dubstep incorporates sub-bass tracks.  This simply means that the frequencies are in or below what is called the contra octave.  Human vocalists that can sing in the contra octave are very rare.  There aren't even more than a few instruments that have the ability to reach such low frequencies.  The frequencies of the contra octave range from about 60 down to about 20 Hz.  The chart below provides some context as to how low dubstep bass goes.

Some dubstep subs do actually go as low as, or around the same frequencies as, the human ear can perceive, around 20 Hz.  Most genres do not even come close to reaching as low as dubstep manages to reach.  This is yet another factor that sets dubstep apart from the rest.

Portamento

The musical term "portamento" discribes the sliding of a tone from one pitch to another in a relatively smooth manner.  This method is often incorporated in the dropping of the bass, giving the climax a smooth and abrupt transition, again balancing the predictable with the surprise (see Rhythm).  The resulting sound wave would go from the bottom waves (seen below) and become more like those at the top of the figure (seen below).
