Oh yes, I wasn't clear on the challenge: the bass in Bb pentatonic scale, the notes are : Bb, C, D, F and G. That's four white notes. The melody is i F# pentatonic scale (that has all the black notes) so this part is perfectly fine. That’s why I consider it’s partially succeeded :)
So the creepy sound is a happy accident. I often find something by accident. And it's clear that doing one jam a week makes us progress.
