I'd like to put together a collection of tips for hip-hop bassists. Some of this goes for all bass playing (or most), but all in all, I hope it's helpful. This is *all* in my experience/in my humble opinion: 1) Hold back. The bass player in this role is almost always a support and rhythm instrument. You're there to hold down the beat and let the vocals do their thing. 2) Play with the kick or beat. Syncopation has its place and can work very well, but in my experience, a lot of great lines come when you just lock with the kick and don't go off of it too much (or at all). A lot of the time when I'm doing a hip-hop line, I intentionally play a staccato "doubling" of the kick-drum part, ONLY playing when the kick hits. For sessions, I use a Buttkicker Platform so I can better monitor the kick for the purpose. 3) Repetition. In my experience, the best grooves come when you get to that Alpha-wave "flow" where you go beyond playing the same thing over & over and let the simplicity of the line take you to a new place WITHOUT going off into variations. 4) Chromatic walks. A lot of hip-hop lines, in my experience, tend to have stepwise motion, but especially when you're going from the b7 to the 1, or the 4 to the 5, a chromatic ascension or descent can really make the line shine. 5) I like to use a really thick, thumpy tone for hip-hop. My Line6 Bass POD xt Live has an effect called "sub-dub" which is really just an doubler, octave-down. Through my Schro 21012L, you can get some serious low-end. I find that, strangely, the best way to get this thick tone is with a bass with a ton of clarity - a modern bass with roundwounds. I like my MTDs for this sound, or my Variaxes on the Alembic, Modulus, MTD, or Steinberger settings. 6) Sometimes it sounds *really* cool to throw in some gospel-sounding slurs and pops, but again, keep it simple... I only really do this at the climax of the song, and otherwise keep it pretty repetitive. There is a magic in repetition and groove/flow that should not be discounted. It's easy to kill a good hip-hop line by overplaying. Use space, use staccato notes on the kick drum hits, and just keep it simple. Please feel free to add to this! I'd love to hear your input as well.
