"In a Trance" is a dance groove with lots of ambience and mood behind it. The chords are Bmi7(b13) - Emi6, which is a VI - II progression.
I'm arpeggiating the main chords so that the notes ring together and sustain over each 2 bar phrase. I added a rock guitar overdub to give the track some energy and punch. Solos can utilize the B Aeolian mode (D major scale), B minor pentatonic, and E minor pentatonic over this track.
