The View from 2005: This is another early article I’m quite proud of. It takes a fresh look at the relationship between two of the three most important elements in the pop/rock mix. Naturally, it made its way into Total Recording.

The Kick Drum/Bass Relationship

The kick drum and the bass guitar are fundamental. I mean, like, fundamental! They represent the bedrock of musical expression, the foundation upon which the house of music is built. This has always been so. The low-frequency impulse and chordal foundation of music is common to virtually all music from all over the world and throughout history. And today’s high-powered, high-tech, industrial-strength rock and roll is no exception. The kick and bass are such an important part of our music that we must give them very special care, especially in recording. As musicians, producers, recording engineers and mix engineers, we absolutely have to fully understand the capabilities and musical significance of these two instruments, both independently and together. They are the primary tools we use to create music which communicates the emotions that live in the pulse, the groove, the chord changes, and the riffs of rock and roll music.

Keep in mind that rock music is very high-energy high-intensity music. It drives the body as well as the soul. And it relies heavily on the low frequencies provided by the kick drum and bass. Low frequency sound waves are generally the most powerful part of the music spectrum. With wave lengths longer than we are tall, low frequencies are felt as well as heard. We humans seem to get a kick out of this. The fact that human-sized bass drums existed before the year 3,000 BC. suggests this is not a new trend. Today we go to dance clubs and live concerts for that special low frequency full-body sensation. For a special thrill I personally like to go to the Fourth of July celebration at out local military-industrial complex, Fort Devens. It is a truly different experience (kind of like riding a rocket sled after driving around in a Yugo) to hear/feel the 5” howitzers let off a 21 round salute from, say, 300 yards away. YIKES!

Power in the Mix

The kick drum is the driving force, the rock and roll motor that makes our body move (in a contemporary echo of the primeval march of the nomad...). Its powerful impact cuts and slams through the rest of the music with a beat which drives our bodies into movement: anywhere from foot tapping to slam dancing. The pulse of music lies in the kick drum.

The bass guitar is the key communicator of harmony in almost any tune. Its deep fat sustained tone is easy for our ears to find in almost any kind of music and it provides a musical foundation on which the harmonies and melodies are built. Add rhythm and words and you've got a song.

In general, the kick drum produces a hard, loud musical attack with little or no pitch, while the bass guitar produces pitch with little attack. As a result, the kick drum is typically rhythmic and the bass usually harmonic. However, they certainly aren't limited to these functions. The bass guitar provides much of the rhythmic force and drive in many styles of music. Slap and pop techniques are a direct attempt to give bass more attack, and this is very effective. At the same time, drummers can provide melodies and harmonies through roto-toms and the various drums (real and synthesized) with definite or implied pitch. In fact, one can do almost anything with these instruments in special situations (move walls, fry eggs, achieve world peace and so on - that’s a joke), but in pop music these instruments really focus on their primary functions. With this in mind, let's consider the implications for mixdown.
