Set up four bars with an 1/8 note grid, and your tempo at 97 BPM. You’re gonna start by writing a basic bass line that plays every 1/8 note. This creates momentum. We’re in B Locrian here, which is just all the white notes from B to B. The Locrian mode is exceptionally dark, and what makes it so dark is the ♭2 (which is C in this example) and the ♭5 (which is F in this example). Now, because those two notes are what make Locrian sound so dark, you wanna be sure to use both of them in your basic bass line. But, start by playing the root note (which is B in this example) for the whole of your first bar, as that anchors it into the key. And by the way, if you find modes confusing, just read the mode hack in our Songwriting & Producing PDF (link opens in new tab).

Next, change your grid to 1/16 notes. You’re gonna create some syncopation now, which is when you accent an off-beat. This will pump energy into your rigid sounding basic bass line and bring it to life. You can add syncopation however you want, but here’s an easy method: shorten an 1/8 note to a 1/16 note, then lengthen the note next to it to fill the gap. Add a couple of these to each of your four bars. And a shoutout to fellow Canadian producer Rezz, as this lesson is based on her recent single “Suffer in Silence”.

By now your bass line will already be sounding good, but to take it to the next level, you’re gonna add some octaves. Rezz does something really cool here. She moves some of the notes that fall on the backbeat snare, up an octave. This accentuates those backbeats, and adds even more energy to the bass line. However, don’t do this on every backbeat snare, as that will actually lessen its impact. Also, somewhere in your bass line, move one syncopated note up an octave. This keeps your bass line fresh and unpredictable. Lastly, here’s a bonus step. Use a rest somewhere. This gives your bass line space to breathe. Rezz used a rest at the very end of her bass line, so we’ll do the same thing by deleting our last two notes.
