Nightcore is characterized by a sped-up melody (sometimes), fast rhythmic beat (usually), and ALWAYS higher than normal pitch. Almost all nightcore music are original songs nightcored (remixed into nightcore) by nightcore fans.
Very popular is a belief that nightcore is a nickname of a person who remixes the songs. In reality anyone who knows how to use a computer can nightcore a song and upload it on Youtube.
"So why d'you listen to it all the time?"
"But even right now you're listening to happy hardcore!"
"It's called nightcore!!"
Pure Nightcore: VERY fast beats (sometimes so extremely fast, that you cannot count them), and very high pitch (almost chipmunks). Song usually lasts about 2 to 3 minutes. Often described as "cute".
Example: Kiss me by Schule321
Bass Nightcore: fast beats, the main melody (and voice) are pitched up, but there's very low bass added; so the contrast between very high and very low is created.
Example: Kiss me by GrizzNightcore
Trance Nightcore: fast beats, high pitch, but less signing and more melody; filled with repetition; very often there is only one verse or a sentence that is repeated throughout the song. Usually it lasts at least 5 minutes, often more.
Example: Kiss me by Nightcoremania
"I used to listen to music while I was on speed, but now I quit the speed and just listen to nightcore instead."
The main characteristic of nightcore is its high pitch often accompanied by fast beat. Very often songs that were remixed into trance, are later on remixed one again into nightcore and so many nightcore songs have trance-like characteristics.
Even though almost any song of any genre can be nightcored, trance and techno songs, as well as electro music and all types of dance music (here especially eurodance) are most often used. Some rock and pop songs are also nightcored. Rap and metal are the two genres that are heavily avoided, and there are very few songs remixed into nightcore.

"Right, and Canada is the most awesome country on the planet."
The software was originally created for artists who were composing music or their own lyrics but may not have access to a singer to perform their works, the software allows the composer to feed their lyrics directly into the program and supply a general pitch range and the program sings the songs back. Yamaha and Crypton created voices based upon Anime characters that they developed to give personality to their sound sets. The first being Yuzuki Yukari based upon a 16 year old Japanese sound actress. Other voice packs followed with both female and male sound sets.
Many Japanese in the Anime cultures embraced VOCALOID and began to hold live concerts during Anime conventions and gatherings featuring VOCALOID generated songs and Muki Muki Dance 3D generated/syncronized versions of the VOCALOID Anime characters to "perform" the songs. The music quickly caught on and spread outside of Japan.
This eventually became an offshoot genre of dance and trance music and has been called Nightcore.
