Mixing your track…

Compose a reggae track with an introspective, melancholic vibe in B flat minor, using a chord progression that includes E flat minor and B flat. Employ an 808 digital percussion kit for rhythm, layer with keyboards, a drum set, and use trumpets to accentuate. Integrate a hand pan and marimba for the melody line. The piece should be bass-heavy with an upbeat mood, incorporate an electric guitar with a 4/4 strum on the first beat using the minor pentatonic scale. The composition should be 45 seconds long, feature an electric bass, and embody a modern reggae dance feel at 120 beats per minute.
