Music Analysis
The 3rd digital single "RUDE!" by SM Entertainment's major girl group Hearts2Hearts is a sweet and bouncy pop-house track described as "cotton-candy house," produced by Sebastian Thott, known for hit songs by ITZY and TWICE.
The backbone of the song is a heavy four-on-the-floor kick drum, a tradition in house music. However, it distinguishes itself from underground, dark club sounds by heavily using light, crisp percussion typical of the Roland TR-808 and syncopated claps, creating a bright and sophisticated groove unique to K-Pop.
The bassline driving the rhythm adopts an approach of "Organ Bass" and elastic "Pluck Bass" characteristic of early 90s digital synthesizers represented by the KORG M1. Rather than pushing with heavy sub-bass, it uses a tight, rubbery, bouncy tone that brings a funky and light propulsion to the entire song.
The sound signature of "RUDE!" is the bubbly, sweet synthesizer main riff that colors the entire song from the intro. A brilliant bell-like pluck sound and a rich pad synth are layered, showcasing a skillful and sophisticated sound design that intentionally transforms the strong words "rude" and "cheeky" in the title into a cute and pop auditory experience.
