Dark Night is a latin trap type beat. The melody, which is played with a guitar is, like every FruityBeatz beat, no sample. Together with the drums it has a lot of groove.
Special about this instrumental is the tempo and the melody. The bpm (beats per minute) is very high and the melody is just one melody through the whole beat. The only change is that one part of the guitar is played in half time and one octave lower.
This beat is either good for singing or rap. It has the perfect tempo to combine both. Maybe the hook is more melodic and the verses are more straight rap. But you can do it however you want.
After all tis is a very well produced beat, that definitely has a latin vibe. There is not that much in that beat, but it is just enough.
