The root-and-octave pattern shows up all over funk, rock, pop, and fusion, and it is a great one to have in your hands! Running it well trains your right-hand thumb-and-pop coordination while it builds left-hand finger independence on the E and D strings. Let's get your bass out and get started.

Set up the right hand first

Line up the joint of the thumb with the tip of the thumb along the string, so that the whole hand moves together as you change strings instead of the thumb angling out on its own. That will keep you from accidentally hitting strings you don't want to hit.

Then angle up a little bit at the wrist so that you are striking with the end of the thumb, just below the nail. The strike is a wrist turn, and it is almost like you throw the thumb into the string and it bounces off. On this line the thumb is only playing the E string, so work on your aim and your tone right there first. You want two things in your slap sound, first a good click, and then a good regular note as if you were picking it normally, and those two elements together are what give you a good tone.

Pop on the side of the first finger

Because the thumb angle turns the hand around a little bit, the first finger ends up rotated as well, so you will be popping on the side of the finger rather than the flat of it the way you would when you pick the string normally.

It is very easy to raise a blister there if you do this too much. As soon as you feel the finger start to get a little bit tender, stop popping for a while and let that tenderness go away, then gradually toughen the finger up. If you wait until you raise an actual blister, you have got to wait for it to heal and start the whole process over again.

Going from string to string, the motion works like this. The thumb strikes down, the hand comes back up, and on the way up the first finger grabs the D string and pops it, which leaves you set and ready for the next thumb.

Four octave pairs across the fingerboard

The left hand plays four octave pairs. In every one of them the lower note is on the E string under the first finger, and the octave sits on the D string under the third finger, two frets higher.

A / A, E string fret 5 (first finger), D string fret 7 (third finger)
F# / F#, E string fret 2 (first finger), D string fret 4 (third finger)
G / G, E string fret 3 (first finger), D string fret 5 (third finger)
Ab / Ab, E string fret 4 (first finger), D string fret 6 (third finger)

After the A-flat you are back at your starting point on the A, and that is the whole line right there!! I recommend working each pair on its own for a short period of time before you move on to the next one.

Lift pressure instead of lifting the finger

This is the part that is easiest to get wrong. When you thumb the low note and then go to pop the octave, you want to lift pressure off the first finger and apply pressure with the third, keeping both fingers in contact with the strings the whole time. It is best that you don't actually pick the first finger up off the string, you just release the pressure so that the first note stops ringing and press the third finger in at the same time. Staying in contact with the strings is what keeps the buzzing and the overringing from bleeding between the two notes.

Put it in time

Count "one-and, two-and, three-and, four-and" and play one pair on each downbeat:

Beat 1, A / A
Beat 2, F# / F#
Beat 3, G / G
Beat 4, Ab / Ab

Loop it. Once it feels solid, put the metronome on and play it through in perfect time, and that is where you find out whether the pressure lift has really become automatic, because any hesitation between the thumb and the pop is going to show up as a rush or a drag. Get it clean at a slow tempo and the whole line starts to feel great!

Key takeaways

Thumb alignment comes first, joint to tip along the string, the wrist angled up, and the strike landing just below the nail. Good slap tone is the click plus the regular note together.
The pop lands on the side of the first finger. Stop as soon as the finger feels tender, before it blisters.
Four pairs (A, F#, G, and Ab), first finger on the E string and third finger two frets up on the D.
Lift pressure between the notes and keep both fingers on the strings.

Slap is one of the fundamentals I teach. For a companion piece on the thumb position itself, see slap hand position. For feedback on your thumb, pop, and pressure-lift, online bass lessons via Zoom are available.

Hello, Russ Rodgers here. Today I'd like to show you an octave slap pattern that can be used over a variety of playing situations. So let's get your bass out and get started. If you need help, refer to your free video on tuning your bass. The first thing you want to make sure you do is have the form of the right hand organized and set up on the bass. The way to start would be to line up the joint of the thumb with the tip of the thumb along with the string. As you move up and down the strings with the thumb, the hand will move this way as opposed to the thumb angling this way. This will prevent you from accidentally hitting strings that you don't want to hit. Once you get the angle set, you angle up at the wrist a little bit so that you're hitting on the end of the thumb just below the nail. When you strike the string, it's a wrist turn — it's almost like you throw the thumb into the string and it bounces off. In this line, we will just be thumbing the E string, so the first thing to do would be to work on striking the E string, getting your aim, and working on the tone. You should have two things in your slap sound: first, a good click, and then a good regular note as if you were picking it normally — adding those two elements of the sound together. The second part of this will be popping the string. The thumb angle will determine where you're popping this string on your first finger. Normally you'd probably pick the string more like this, but when you're thumbing and keeping the angle of the thumb the way it needs to be, it's going to turn the finger around a little bit this way so that you'll be popping on the side of the finger as opposed to the flat of it like you'd normally do when you pick the bass string. I caution you to be very careful on this part because it's very easy to raise a blister if you do this too much. My recommendation would be, as soon as you feel your finger start to get a little bit tender, stop popping for a while until that tenderness goes away, and gradually toughen up the finger. Because if you wait till you raise a blister, then you've got to wait for the blister to heal and start the process all over again. So the thumb and the pop — I strike down, and then as the hand comes back up getting ready for the next thumb, you grab it with the first finger. Just on one note on each of the E string and the D string, work on popping the octave. The notes you will use in the left hand will be first finger fifth fret on the E string, which is your A, and third finger seventh fret on the D string, which will be your octave A. So your low A, first finger fifth fret on the E string, which you'll hit with your thumb, and then when you pop you'll pop the seventh fret on the D string with your first finger. When you do the thumb-pop, you want to make sure you lift pressure off one note before starting the other note. So when I thumb the A on the E string and then I go to pop the A on the D string, I'll lift pressure on the first finger and then apply pressure on the third finger. It's best that you don't actually leave the string and pick your finger off the string — just lift pressure, staying in contact with the strings as you do this. The second group of notes will be the F# on the second fret of the E string with the first finger, and then the octave played with the third finger on the fourth fret of the D string. The next group of notes will be the G, first finger third fret on the E string and third finger fifth fret on the D string. The last group of notes will be the A-flat played first finger fourth fret on the E string, third finger sixth fret on the D string. And then you're back at your starting point on the A. To get comfortable with the line, I recommend working each of these groups of notes for a short period of time, then moving to the next. Now we'd like to put the line in context into a slow time where we will count "one-and, two-and, three-and, four-and." You'll play each group of two notes one time with the count: one-and, two-and, three-and, four-and; one-and, two-and, three-and, four-and. Now we're going to play the line one more time in its entirety with the metronome click to work on playing it in perfect time. Once again, I'm Russ Rodgers, and thanks for watching this video. We'll see you next time.
