A video about the Metro Boomin "10 Freaky Girls" trap scale in under 4 minutes. This was one of the most requested music theory videos. It's a dark trap song that features 21 Savage. It has a Kashif and Whitney Houston sample from "Are You The Woman". Metro Boomin produced this record by himself. It appears on the "Not All Heros Wear Capes" LP. This dark trap scale is very simple and effective. I use the Akai Fire to show off this scales potential.
