A music theory video about the trap scale TM88 used on Future's "Call The Coroner" song. The first 6 bars are  a F# Dorian mode (F#, G#, A, B, C#, D#, and E). The last 2 bars are a B minor scale (B, C#, D, E, F#, G, A). The F# is the tonic(dominant note) which is great for circular (repetition) play. The mood of this scale is scary, dark, jazzy, and bluesy. It's great for horror film scores or for very dark songs. Many heavy and death metal bands use this scale. Let me know how you feel about this tutorial below.
