Musical Style

As a whole, Super Junior has released three studio albums and one official single, including contributions of songs in the soundtracks of H.I.T and Attack on the Pin-Up Boys. They are acclaimed for their vocal harmonization and unison as each member contributes a different voice range in their music.[77] Some members are credited for their vocal belting techniques, notably Yesung.[g][78] Leeteuk, Heechul, Han Geng, Sungmin, Donghae, and Ryeowook sing within the stretch of a high baritone range to the tenor range, while Kang-in and Siwon sing in a lower baritone range. Shindong's, Kibum's, and Kyuhyun's vocals lie in the bass range. Shindong, Eunhyuk, and Kibum are also the known rappers of the group due to their rhythmic vocals and quick tongue. Heechul and Donghae consistently rap as the supporting vocals.[h]

Super Junior's music mainly fall into the category of mainstream Korean pop. Songs of this genre are usually mixed with different branches of electronic instruments, with heavy emphasis on urban contemporary, dance pop, and rap. Super Junior has been notable for their light, bubblegum pop dance mixes, such as "Miracle", "Dancing Out", and "Full of Happiness", although a majority of their promotional singles incorporate mature music and lyrics. Don't Don's first promotional single "Don't Don" includes a balanced infusion of rock, R&B, and rap, along with other musical elements like the electric guitar, bass, and other different percussion instruments, adding to a mixed genre labeled as SMP.[79] Classical instruments are also woven into their music, such as the violin in "Don't Don" and the African djemba and Indian tabla in "A Man In Love."[80] They have also released songs that are solely focused on rap and hip hop. An example is "One Love", a song that Eunhyuk wrote for their first concert.

Super Junior has covered quite a few song in their albums. Their debut single, "TWINS (Knock Out)" is a cover of Triple Eight's "Knockout," which was released in 2003. While the musical style is mostly maintained as the original, "TWINS (Knock Out)" touches closer to rap rock, with quicker rap and more emphasis on the bass instruments. In most of their covers, the original titles are kept. Examples include Cape's "L.O.V.E" and Exile's "Believe." However, most of these covers are re-arranged to different accompaniments, such as H.O.T's "Full of Happiness".

Heechul, Shindong, and Eunhyuk are credited for their rap lyrics in their co-single with TVXQ, "Show Me Your Love". Eunhyuk is also the main contributor for the rap lyrics in the group's single, "U" and as well as the majority of the rap lyrics for Super Junior's later albums. After the release of their second album, more members began to contribute in writing. Leeteuk, Sungmin, Eunhyuk, and Donghae wrote the lyrics to the pop track, "I am," a song talking about the ordinary man in a celebrity's life.[5] Ryeowook also composed and co-wrote the lyrics with Sungmin to "Love U More", a track released on their 3rd album's repackage.[5]
