One of the biggest hits for Carnival 2019 is Mr Killa’s Run Wid It.
For those unfamiliar with the style, it is referred to as Jab, a sub-genre of soca which I posted on before. In terms of soca, there are no better musical sub-generes suited to talk about spiritual possession more than Jab because Jab, for all intents and purposes is possession/trance music. It ticks all the boxes. For example:
- Jab like other possession music is all about the repetition. You need to say stuff over and over.
- Jab has no chords. There is also little to no harmonic movement in possession music (chords, chordal instruments like a piano or guitar), especially with possession music of the African diaspora.
- Jab music is rhythmic.
To see what I mean check the music from Cuban Santeria below:
It is obvious, Jab is meant to induce possession.
The psycho-acoustic explanation for this is that the repeated patterns lead to less distraction which in turn can manipulate the trance-like state. For the more spiritual, these rhythms carry with them certain deities and given the reaction to this song, I think the latter definitely has a point. Check below:
So that my friends a brief look at Jab and its relation to possession music. Whenever this song plays, just be careful, it is meant to take a HOLD of you.
