Hanging On begins in a subdued atmosphere with the soft plucking of a harp audible beneath Ellie's enchanting soprano voice. I love the use of a harp. As the lyrics enter, the production slowly increases in dynamic and becomes thicker, progressing into soft dubstep. Tinie Tempah interrupts the captivating vocal with his usual high energy rapping, attacking the beat laid before him which gives a great contrast within the track. The constantly moving pitch of the vocal is reminiscent of The Weeknd but this is shunned by the ever changing range in production, as it grows and diminishes. It's just a really well produced track okay.
