Trivia:

Despite being a large thirteen member boy band with the members having a variety of different vocal ranges, Super Junior are often praised for their vocal harmonization and unison. Some members are credited for their vocal belting techniques, notably Yesung. 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.

Super Junior-K.R.Y
Super Junior-K.R.Y, established in November 2006, is a trio formed by Kyuhyun, Ryeowook, and Yesung. The company discovered that these three members developed a particular persona and subsequent fan-base that was separate from the rest of the group, and how they also had similar musical qualities. They therefore grouped these three members together to perform particular songs to target a more mature audience. Being amongst the most vocally powerful members of the group, Super Junior-K.R.Y are credited to singing mournful, R&B-style ballads, a style that has proven very popular in recent years although stagnation in the style's development is causing it to lose its once fresh evocative power.
Super Junior-K.R.Y's first official performance was on November 5, 2006 on KBS's Music Bank, performing "The one I love." They have participated in the original soundtrack of the tvN drama Hyena with a total of three tracks, including the main theme. The trio also contributed tracks in two additional original soundtracks, one track in both the soundtracks of Snow Flower and Billy Jean Look at Me. Unlike Super Junior's other sub-units, Super Junior-K.R.Y has not officially released a single or album, and only participated in collaboration albums and original soundtracks. However, a comeback album is expected from K.R.Y in the future.
