Title: Karaoke system
Inventor: MATSUMOTO SHUICHI
IPC: G10H1/00
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a KARAOKE system (orchestration without lyrics) with which plural singers can be participated and enjoy singing together. SOLUTION: A microphone 1 for main vocal is provided for singing a main melody and a microphone 2 for sub-vocal is provided for singing a harmony melody. Since the musical scale or the start to sing is difficult for the part of harmony melody in comparison with the part of main melody, ordinary singers can not be participated considerably. Then, a correction part 5 corrects singing voice signals inputted from the microphone 2 for sub-vocal so as to be exactly matched with the pitch of harmony melody and outputs them to a mixing part 4. Thus, even a person, who can not sing the harmony melody well, can be easily participated as sub-vocal.
