Among the many things that grew up with rock & roll—groupies, distortion, instrument immolation, pool-tested TVs—the bass guitar ranks near the top. While initially devised as a cheap and portable substitute for the upright, the bass guitar immediately resonated with proto-rockers of the ’50s who appreciated its portability, but were even more turned on by its authoritative sound. A beautiful relationship was born, and like many good relationships, the happy marriage of bass and rock has depended on one stable characteristic: in this case, the eighth-note.

Like it or not, if you’re in a rock band, you’re going to play eighth-notes. A lot. So why do many of us spend our time practicing everything but? I think it’s because we suffer from eighth-note inferiority complex, as if practicing them somehow reinforces the shameful stereotype that bass playing is easy. Banish this thought! Playing solid eighth-notes that propel the groove forward, reinforce the melody, and inject clever rhythmic dislocation is no cakewalk under the best circumstances, much less while bouncing around a beer-slicked stage in the near-dark.

If you’re convinced that eighth-note practice is time well spent, where to begin? To me, making it fun depends on your appreciation of nuance—your ability to step back and think objectively about how your bass line is affecting the song. Of course, you must practice the dry technique of solid eighth-note performance, like ensuring evenness between each note by using good pickstyle (Learn To Play, April ’05) and fingerstyle (May ’05) techniques and using plucking and fretting-hand muting to beneficial groove-effect (May ’05 and March ’05, respectively). But you should also factor in some thinking time. Ask yourself questions like: Is my note slamming with the snare drum on two and four? Should it? Would it be cooler to hold a few notes for an extra beat? Are my durations helping or hurting the groove? What if I played around with dynamics, making certain notes louder or softer to better serve the vibe?

Putting your brain to work will not only make playing eighth-notes more stimulating, it’ll make you a better bass player.
