Use These Notes to Make Grime Bass Lines

When you want a heavy bass line, do you find yourself clicking through your sounds trying to find something that makes your bass heavy? Well, sounds don’t make bass lines heavy, the notes do. So in this video, you’ll learn what notes to use to make your bass lines heavy, regardless of the sounds you’re using. But first… tea!

THEORY

The legendary London grime producer & MC, SKEPTA, just dropped his new single “Wish You Were Here”. This track is the epitome of London’s grime sound, with its string arpeggios, dissonant bass, and syncopated drums. However, Skepta has a secret scale up his sleeve, which takes this tune to the next level. Now, it’s no secret that Grime producers love the Phrygian mode for its ♭2 (for example, if you’re in A Phrygian, the ♭2 is B♭). And if you’re familiar with modes, you’ll know that Phrygian is minor. And if you’re not familiar with modes, just keep watching cos we’ll explain Phrygian in a minute. So, here’s where the grime veteran kicks things up: Instead of playing the ♭3, he plays the 3, thereby turning Phrygian into Phrygian dominant (AKA Phrygian major), which is a very rare scale! And please note, there are many different (and better!) names for this scale, but Phrygian dominant is probably the most common name for it in the West. And finally, as if a rare scale wasn’t enough, Skepta throws in another note that isn’t even in Phrygian or Phrygian dominant, the 7. And by the way, if you’re new to the concept of musical spelling, which is when we assign numbers to notes (like 7), then read the fourth hack in our free book “12 Music Theory Hacks to Learn Scales & Chords”. And if you’re new to the concept of flat numbers (like ♭3), then read the eighth hack in the book, which you can download below.

SETUP

Alright, now you’re gonna learn how to use this theory to make your own version, and what you see on the screen right now is our version that we made earlier. So, start by setting up two bars of 4/4, with your grid set to 1/16 notes, and your tempo set to 135 BPM. Skepta uses B♭ Phrygian dominant, but we’re using A, cos there’s fewer flats, so it’s easier for learning.

STEP 1.  “SKEPTA SCALE”

First things first, let’s talk about what Phrygian is. And that story begins with the Aeolian mode (AKA the natural minor scale), which is what you get when you play all the white notes, with A as your root note (in other words, your scale’s home). Now, to turn the Aeolian mode into the Phrygian mode, all you do is move the second note (B) one semitone down (to B♭). Then, to turn Phrygian in to Phrygian dominant, all you do is move the third note (C) one semitone up (to C♯), which changes the scale from minor to major. And finally, throw in that naughty note that is not in Phrygian or Phrygian dominant, the G♯. So, here is the “Skepta scale”: A B♭ C♯ D E F G G♯. And if you wanna start it on B♭, like Skepta does in his track, then just select all the MIDI and move it one semitone up.

STEP 2.  BASS LINE

Right, now that you know the “Skepta scale”, it’s time to use those notes to write your bass line. So, start by playing the root (A) for a 1/4 note, then complete the rest of your first bar with the notes A, C♯ and G, which outlines an A7 chord. Then in your second bar, start by playing the ♭2 (B♭), which creates that classic grime sound. Next, complete the rest of that bar with the notes G and B♭, which outlines a Gm chord, and then throw in that naughty G♯ somewhere towards the end. And lastly, for maximum groove, use plenty of rests and off-beats.

Right, now that you’ve got one section down, how do you write more sections for it, and then, how do you transition between those sections, and turn 'em into a song? Great questions, and if this is something you need help with, then check out our cutting-edge online apprenticeship course, where you’ll literally learn every step of the music making process, and most importantly, you’ll learn how to finish your songs! You’ll also gain access to our private network, which is a safe online space (i.e. social media platform) exclusively for our 600+ apprentices from 50+ countries. Our Network is a super supportive place for you to ask theory questions, share your music, get feedback, meet like-minded music makers, and collaborate!
