Funk / Soul

Funk and Soul music are both genres primarily originating from African-American communities, heavily influenced by gospel, blues, and rhythm and blues, and characterized by strong rhythms, syncopation, and a focus on danceability. While both share common roots, funk emphasizes instrumental, rhythmic drive and "groove," while soul often focuses on vocal expression and emotional intensity. 

Funk:
Emphasis: Groove and rhythm, with syncopated basslines and percussive elements. 
Instrumentation: Heavy use of electric bass guitar, drums, horns (like saxophones and trumpets), and sometimes guitar and keyboards. Characteristics: Strong, repeating rhythms, often with a focus on the first beat of a measure ("the one"), and a percussive feel.

Notable Artists: James Brown, Parliament-Funkadelic, Sly and the Family Stone, The Meters. 

Soul:
Emphasis:
Vocal expression, emotional intensity, and often a blend of gospel and blues influences. 
Instrumentation:
Can vary, but often includes vocal arrangements, horns, and a rhythm section, but may not always heavily feature electric bass in the same way funk does. 
Characteristics:

Overlap and Relationship:
