souldeling
The act of singing notes all up and down throughout three different octaves in five lyrical syllables or less. Technique made most popular by boy bands like All 4 One and Boyz II Men, its purpose is to convey a deep flowing current of emotion, yet sounds more like a vocal epileptic seizure revealing the singer's inability to hold a note for longer than half a second.
The end of that sappy-ass All 4 Men song "I Swear" where the singer hits no fewer than 22 notes in the three syllables "Oh, I swear" is a prime example of souldeling.
