All the instruments, melodies and arrangements have been 100% made by the producer. No free-royalty use loops have been used to create any part of the instrumental of this track. There can only be loops only in the drums section (claps, shakers, top loops, etc) and ambient or vocal samples as a support of the production arrangement.
Process note
The chords have an important role in the beat's nature. In fact, they give the right accent to it. The drum's rhythm follows an interesting swing. But the more particular feature, in my opinion, is the bassline which represents the real drive of the piece.
