It's a computerized program that let's users create their own music with; with permission; of the vocals of a real person, and is appeared to be sung by an animated anime style characters.
The vocals maybe from an actual person, but are not literally sung by them. It's all computerized.
Hatsune Miku being the most popular; and the love of my life in music; is one of them.
Others include Kagamine Rin, Kagamine Len, Kaito, Megurine Luka, SeeU and many more.
There are also non-Vocaloids which are completely related to Vocaloids, but are not considered to be apart of them. They are referred to as, UTAU.
Two of my favorites from UTAU are Sukone Tei and Kasane Teto.
Sukone Tei being the psychotic murderer singing UTAU, and Kasane Teto being the most popular UTAU, similar to Hatsune Miku.
Vocaloid and UTAU have become very popular and almost well known though out the world. If you haven't heard of them, now you have. Also there are Vocaloid / UTAU concerts in Japan and I think in California in the United States. I'm not lying about that either. I wish I could go be there at a concert myself. But that's probley not going to happen.
So. Let's share videos and/or discuss Vocaloids and UTAUs!
I'll start by sharing 3 songs of Hatsune Miku, and 1 of both Sukone Tei and Kasane Teto.
