Anchor the root — 16 of 18 notes
In the rolling pattern from our CONCRETE pack (A minor, 132 BPM), 16 of the 18 notes are the plain root. The only travellers are two octave pops and two passing fifths — one of each per bar — everything else is A, holding the floor down. A bassline’s job is harmonic foundation, not melody: when 70% or more of your hits are the root, the groove gets heavier, not emptier.
Try it: count your last bassline’s notes. If the root is under 70%, delete the travellers first and see what survives.
