This disco bassline features a blend of sawtooth and square waves at 110 BPM in the key of E, combining the growl of a sawtooth with the hollow vintage tone of a square wave to emulate a finger-style bass. The notes alternate between E1 (41.2 Hz) on the downbeats and E2 (82.4 Hz) on the off-beats, with a subtle variation on the last bar introducing D2 and Eb2 for a turnaround. A fast attack and 250 ms decay amplitude envelope creates a percussive pluck, while a 4-pole low-pass filter at 550 Hz shapes the sound to be round and groove-focused. Subtle tanh saturation adds warmth, with a 30 Hz high-pass filter cleaning up sub-bass rumble.
This bassline suits disco, funk, and nu-disco styles at 110 BPM or nearby tempos. It can be layered with drum grooves or synth stabs for a classic dancefloor vibe, but watch for low-end clashes since the sound is centered and focused in the low-mid range. Adding light compression or subtle chorus effects can enhance presence without muddying the mix.
