Theory
Today is the heart of this week — muting. Eighty percent of a bass's sound comes not from playing well but from killing the strings that shouldn't ring. One note rings clearly while the rest stay quiet — that's a pro's cleanliness. Today you learn to switch sound off just as much as to make it.
Both hands take part in muting. First the left. Ease off the pressure of the fretting finger just a touch, and the string lifts from the fingerboard so the sound cuts off cleanly. You don't lift it all the way — you keep the flesh resting on it and just release the force, like flipping a switch off. This "press, then release the force" is your first tool for shaping note length with your hand. Once you're used to this control of force, your hand decides on its own whether to cut a note short or let it ring long.
The right hand is a gatekeeper too. Cover the strings lower than the one you're playing lightly with your thumb and the fingers you didn't pluck, putting them to sleep. When you pluck a string with one finger, the next finger naturally lands on it and cuts off the ring. When both hands cooperate like this, even a string you brush by accident won't sound. This habit of covering the strings you don't play in advance is the real secret to a clean, noise-free sound on stage.
Sometimes you add a ghost note ("chk") on purpose. It's a muted strike with no pitch, just a "chk," and it adds groove to the rhythm. In the score it's marked with an X instead of a note. On a 5-string there's one more string to put to sleep — keep the low B covered with your thumb, so you need to mind muting a little more than on a 4-string. Today's goal is just one thing: one note rings, the rest fall silent.
See it
Today you look at two examples for cutting sound off. First play a note and put it right to sleep to make silence, then feel the groove with a pulse that mixes in ghost notes. In the score, an X is a muted strike with no pitch (a "chk"). Each example is laid out in a 4-string and a 5-string version.
Example 1 — play and put to sleep. Play the open E, then immediately ease off your left hand to cut the sound. The next beat is an X — a muted strike with no pitch. Make "sound → silence" split clearly.
▶ BPM 60, 4-string. Play the blue open E → then immediately release the force to put it to sleep as an X (chk). Let sound and silence split into equal half-beats.
▶ BPM 60, 5-string. The note and position are identical to the 4-string. Cover the low B with your thumb so it doesn't ring along even when you play the X.
Example 2 — ghost pulse. Alternate the open E and a ghost note (X) eight times. The goal is to get a "dum-chk-dum-chk" groove into your hand.
▶ BPM 65, 4-string. On-beats are the blue open E, off-beats are the X (chk). The clearer the volume difference between the two, the more the groove comes alive.
▶ BPM 65, 5-string. The notes are identical to the 4-string. Keep the low B covered with your thumb so it doesn't leak through even as you speed up.
Today's practice
0–7 min · Warm-up Loosen up again with yesterday's low roots on the E string at BPM 60. First check that your fingertip lands right behind the fret.
7–17 min · Today's skill Repeat Example 1 (play and put to sleep) at BPM 60. Focus only on whether the sound cuts off cleanly the moment you release the left hand, leaving no ring.
17–27 min · Applying it Repeat Example 2 (ghost pulse) four times at BPM 60 → once "dum-chk" splits clearly, raise it one step to BPM 65 for four more. If the sound smears, go back to Example 1.
27–30 min · Check Write down the BPM you reached, and record 30 seconds to hear whether only the played note rings and the unplayed strings stay quiet.
Done when: with left-hand release and right-hand muting, you can cut the sound off cleanly at 60–70 so that one note rings clearly and the unplayed strings stay quiet.
- Lifting the finger all the way. Releasing the force and lifting off are different. Keep the flesh resting and only release the force so you flow right into the next note.
- A ring lingers. If it hums even after the sound cuts off, cover that string with your right thumb or a finger to press down the resonance.
- Ghost note too hard. Hit the "chk" hard and a pitch comes back, muddying it. Very light — just the sound of a muted strike.
- Neglecting the low B (5-string). Focus on muting and drop the B, and the low end hums and leaks. Always keep your thumb resting on the B.
