When the singer starts singing at the singer's singing portion, the pitch detection unit 27 detects pitch information of the singer's voice in synchronization with this singing portion (step S22). The pitch information detected by the pitch detecting section 27 is analyzed by the CPU 11, and the performance key is changed and controlled so as to match the performance key with the detected pitch information (step S23).

Based on the range information of the highest and lowest tones in the song data and the change key obtained in step S23, the highest and lowest tones in the performance song at that key are obtained (step S24). When the highest note and the lowest note in the performance music in that key are obtained in step S24, they are compared with the highest note and the lowest note in the vocal range of the registered singer (step S25). As a result of the comparison in step S25, (the calculated highest note in the performance song) ≦ (the highest note in the registered singer) and (the lowest note in the calculated performance song) ≧ (the lowest note in the registered song) ) Is determined (step S26), (the calculated highest note in the performance song) ≦ (the highest note of the registered singer) and (the lowest note in the calculated performance song) ≧ ( Only in the case of the registered singer's lowest tone), the performance is continued with the key as it is (step S27).

Thereafter, it is sequentially checked whether or not the music is over (step S28), and the operation of continuing the performance is repeated until the end of the music. When the end of the song is detected in step S28, the performance ends. Step S26
As a result of the judgment, whether (the calculated highest pitch in the performance song) ≤ (the highest pitch of the registered singer) or (the lowest pitch of the calculated performance song) ≥ (the lowest pitch of the registered singer) If not, the performance is stopped or a warning is issued (step S29). If the performance is selected to be stopped in step S29, the performance ends immediately. Step S
If the warning is issued at 29, the step S
Proceed to 27 to continue playing.

In step S29, which one of the performance stop and the warning may be selected may be set in advance so that one of them is always selected. For example, the calculated highest and lowest notes in the performance music. The highest sound of a singer registered as a sound
Depending on the size of the difference from the lowest note, the performance may be stopped when the difference is larger than a predetermined value, and a warning may be issued when the difference is less than the predetermined value. Therefore, in the device of the second embodiment, the singer, by registering the vocal range information in advance, sings at a pitch suitable for his / her vocal range at the singing part regardless of the key of the prelude part. After that, it is judged whether or not you can sing to the end with that key, so you can enjoy karaoke with the appropriate key that suits your vocal range, and you do not need to perform complicated pitch adjustment operation. You can foresee that there are places that can't be sung, so you don't have to feel uncomfortable at that place. Also, without automatically adjusting the keys, by simply registering the vocal range information in advance, even if it is determined whether or not the keys set by manual adjustment etc. can really sing to the end, You can know whether or not the key is suitable early, so
You can easily enjoy karaoke with the appropriate key that suits your voice range.
