# Instrument VIII, Bass Synth There are all sorts of ways to synthesize bass sounds. In general, it needs to have a strong fundamental note, a sensible amount of higher harmonics so it can be heard on smaller speakers, and it music make rhythmic sense with the rest of the track. > [!cite] Lore > ![[8-tiger-shark.png]] > Tiger Shark (art by Dead Carcosa) A common approach to bass sounds is to use a sine or triangle wave to create a sub bass. Another approach is to take a saw wave through a low-pass filter to get a Moog Taurus-esque bass. ## Wobble Bass From [[Signal Music V, Melody]]. This bass synth is two detuned saws through a low-pass filter. A triangle-wave LFO provides the "wobble" which modulates both the amplitude and the filter. The wobble is determined in quarter-note intervals. Every quarter note, a random value from 1-8 is chosen. That amount of wobbles will occur during the next quarter-note interval. > [!example] > ![[image-58.png]] > The wobble bass synth. ## PWM Drone Bass From [[Signal Music, Atmosphere]]. > [!example] > ![[image-112.png]] > A drone bass synth using pulse-width modulated square waves.
