Vocaloid is not a single artist, but a voice synthesizer software developed by Yamaha that allows users to create music using virtual singers. Each Vocaloid voicebank is associated with a character, such as Hatsune Miku, Kagamine Rin & Len, and Megurine Luka, who have become iconic in digital music culture. These characters are often credited as the "artists" behind Vocaloid songs, though the actual music is composed and produced by various creators from around the world. Vocaloid has had a major impact on pop and electronic music, inspiring a global community of fans and musicians.
