This tutorial is about building an Alix Perez-style sub bassline that shakes.

The category here is basslines, so the main goal is a usable bassline and sub pattern. We’re focusing on sub, low end, note phrasing, bass movement, and rhythm against drums. The result should be a low-end groove that feels heavy, simple, and controlled.

This is not a lesson about effects, transitions, or arrangement tricks. It’s a beginner tutorial on writing a bassline with the right sub movement. You’ll learn how to place notes, shape a clean sub tone, and make the bass talk to the drums. The main payoff is a usable sub bassline you can drop into a track.

Think deep, restrained, and physical: a bassline that moves air without too many notes.

Alix Perez-style sub writing often feels minimal, but it is never random. The bassline usually wins by doing a few things well: strong note choice, careful spacing, tiny rhythmic shifts, and a solid relationship with the kick and snare. For a beginner, that’s good news, because you do not need a complex patch. You need a simple sub and a phrase that feels confident.

You’re going to build a one- to two-bar sub bass pattern that can loop cleanly and feel weighty under drums.

The goal is to create a usable bassline in the style of deep, shaking Perez-inspired low end.

Your finished result should have a clean sub sound, a short repeating sub pattern, clear rhythm against drums, a little bass movement without becoming busy, and a groove that still sounds strong when kept simple.

A good beginner target is a key like F minor, E minor, or G minor, with a tempo around 170 to 174 BPM, one main root note, one or two extra notes for movement, and enough space between notes so the low end can breathe.

By the end, your bassline should feel deep, controlled, punchy with the drums, and easy to extend into a full track.

Start with a very simple drum idea: kick on beat one, snare on beat two, kick on beat three, and snare on beat four.

You can add hats later, but for now keep it basic.

This step matters because sub basslines make more sense when written against drums. In this style, the bassline is not just a note sequence. It is a rhythmic partner to the kick and snare.

A good beginner tip is to loop only one or two bars. That makes it easier to hear whether the bassline actually grooves.

At this point, you have a drum grid that the bassline can lock to.

Next, make a simple sub patch.

Use any synth with a sine wave or a very clean triangle wave. Start with one oscillator, a sine wave if possible, mono mode, legato off for now, a short attack, a medium-short release, and no big effects.

A good starting envelope is a very short attack, little or no decay, full sustain, and a release that is short enough to stay tidy but long enough not to click.

If your synth has saturation, add only a little. The point is not to turn the sub into a loud mid-bass. The point is to keep the low end solid.

This works because a clean sound helps you hear phrasing clearly. If the patch is too complex, beginners often confuse sound design with groove.

Now you have a playable sub sound ready for bassline writing.

Next, choose one root note and stay there first.

Pick a key and begin with just the root note. For example, in F minor, start with F.

Write a very basic pattern using only that note. Try placing one note after the kick, leaving space, then placing another note before or after the snare. Avoid filling every gap.

A great beginner move is to make the first pattern almost too simple.

Think of one short note in the first half of the bar, one longer note in the second half, then loop it.

This step matters because the shake comes from timing and weight, not from lots of pitch changes. A single-note sub pattern can already feel powerful if the rhythm is right.

Now you have the first version of a usable sub pattern.

Next, line the bass up around the kick, not directly on top of it.

Adjust the note starts so the sub does not constantly sit exactly on every kick hit.

Try letting the kick hit first, then bringing the sub in just after. Leave beat one cleaner than you think. Try a note that leads into beat two or beat four. Let some notes end before the snare so the groove feels tighter.

This style often feels heavy because the bassline and drums are interlocked, not stacked directly on top of each other all the time.

Here’s a useful test. If the low end feels blurry, there is probably too much overlap. If the groove feels stiff, the notes may be too locked to the grid and too constant.

At this point, your bassline should feel more connected to the drums.

Once the root-note loop feels good, add one movement note.

Good choices are the note below the root, the note above the root, or the fifth of the key.

If your root is F, you might test E-flat for a darker pull, G for a slight lift, or C for a stable supporting tone.

Use this extra note sparingly. One note at the end of the bar, or one short passing note, is enough.

This is still a sub bassline, so pitch movement should be deliberate. Too many note jumps can weaken the low end and make the phrase feel small.

Now you have bass movement without losing the deep sub focus.

Next, shape note lengths carefully.

In this style, note length is a huge part of phrasing.

Try three note-length ideas: short notes for punch and bounce, medium notes for steady groove, and one longer held note for weight.

A good beginner formula is a short first note, a medium second note, and a slightly longer final note.

Listen for this. If every note is long, the bassline may feel lazy or muddy. If every note is short, the bassline may lose weight. If there is contrast, the low-end groove feels more musical.

This is one of the main secrets of convincing sub writing: the notes do not just change pitch, they change shape.

Now your bassline has more natural note phrasing.

Once the core pattern works, you can try one subtle expressive move.

You could use a very short glide into one note, one legato overlap between two notes, or a tiny pitch scoop on a transition note.

Keep it subtle. The aim is not a flashy lead-bass sound. The aim is a small bit of movement that gives the phrase a human feel.

If you do not like the result, remove it. In this style, restraint usually wins.

A good beginner rule is this: if the slide is the first thing you notice, it is probably too much.

Now you have the option of a slightly more alive bass phrase.

You can also layer a very light reese above the sub if needed.

This part is optional, but useful if your pure sub is too hard to hear on small speakers.

Add a second layer using a saw or square source, filter it heavily, keep it much quieter than the sub, and place it in the low-mid area rather than making it huge and bright.

This upper layer should follow the same notes as the sub.

Keep the priority clear. The sub carries the weight, and the light reese adds texture and note audibility.

Do not let this become the main sound. The outcome still needs to be a low-end groove led by sub bass.

At this stage, your bassline may read more clearly without losing depth.

Now check the groove in mono and at low volume.

Listen quietly, then check in mono if you can.

Ask yourself: can I still feel the rhythm of the bassline? Does the root note feel solid? Do the movement notes feel intentional? Does the kick still have room?

This kind of bassline should still make sense when played softly. If it only works when loud, the phrasing may not be strong enough.

That confirms whether the bassline itself works, not just the volume.

If your one-bar loop feels good, turn it into a stronger two-bar phrase.

Duplicate it into two bars and make only one small change.

Good changes include removing one note in bar two, shortening the last note in bar two, swapping one root note for the movement note, or adding a tiny legato phrase only once.

This creates a more musical sub pattern while keeping the identity of the loop.

A nice beginner target is this: bar one establishes the groove, and bar two answers it with a small variation.

Now you have a more complete usable bassline.

There are a few common mistakes to watch for.

One is using too many notes. Beginners often think a stronger bassline needs more notes, but in deep, sub-driven styles, the opposite is often true. A good fix is to mute half the notes and see if the groove gets stronger.

Another mistake is putting the sub directly on every kick. This can make the low end crowded and less physical. A good fix is to let some bass notes start just after the kick, or leave more space on beat one.

Another mistake is making every note the same length. That removes phrasing. The fix is to combine short, medium, and longer note lengths.

Another common problem is adding too much reese too early. If the upper layer becomes the star, the bassline stops feeling like a sub-led groove. Turn the reese layer down until you miss it when it’s muted, not until it dominates.

Too much pitch movement in the sub is another issue. Large jumps can sound unstable in the low end. Keep most of the pattern near the root and use only one or two movement notes.

And finally, do not judge the bassline without drums. A sub pattern may sound boring on its own but perfect with drums. Always test your bassline against the kick and snare loop.

Here’s a short practice exercise.

The goal is to build one beginner-friendly Alix Perez-style sub pattern in fifteen minutes.

Load a drum loop with kick and snare only. Create a clean sine sub patch. Choose one root note. Write a one-bar pattern using only that note. Move the notes so they groove around the drums. Add one extra note for movement. Change at least one note length. Then duplicate it to two bars and add one tiny variation.

The outcome you’re aiming for is a usable bassline that feels heavy, simple, and clear.

Check yourself with a few questions. Does it still feel strong with very few notes? Does the sub rhythm work with the drums? Can you hear one clear repeating phrase? Does bar two add a little variation without ruining the groove?

If the answer is yes to most of these, you have a solid beginner result.

To recap, this lesson stayed focused on basslines, specifically an Alix Perez-style sub bassline that shakes.

The main points are: start with drums, use a clean sub, build from one root note first, make the groove with rhythm against drums, add only a little bass movement, use note length for phrasing, and keep any reese layer supporting the low end rather than replacing it.

The goal is to write a deep, simple bassline. The step is to build it from root-note rhythm, then add one movement note and a small variation. The outcome is a usable sub pattern, a low-end groove you can actually use in a track.
