urban yodeling
When a singer draws out or oscillates notes excessively (seems to have been started by the ilks of Mariah Carey, Whitney Houston and Christina Aguilera) Especially when covering music written by others. And can be heard in karaoke bars.
Besides drowning out the shrill Aaron Neville, Aretha Franklin destroyed the National Anthem with her urban yodeling.
urban yodeling
using electronic means to change vocal inflections, used mostly in hiphop or pop music. Generally used to mask a lack of singing talent
Kanye uses autotune and other electronic means to alter his singing voice in order to appear that he can actually sing. The end result sounds like urban yodeling.
