Slap-bass solo, looped live: "Swagger"

Style read

Narration & commentary

Charles Berthoud builds a rich groove by first recording a syncopated slap-and-pop bassline, then stepping on his loop pedal to lock it in. Over this foundation, he layers a rapid-fire percussive rhythm using muted thumb-slaps before introducing a bright, melodic third voice played with precise two-handed tapping. The magic lies in his flawless timing and hand independence, transforming a single four-string bass into a self-contained rhythm section.
