PROBLEM TO BE SOLVED: To check the interval of specified music previously at reproduction time by providing a means which takes out the highest interval part of reproduced music, a means which repeatedly reproduces the highest interval part for monitoring, an interval adjusting means which adjusts the interval of the reproduced music, and a means which reproduces the music after the interval is adjusted. SOLUTION: A system controller 9 reads time information out of the place where the highest interval of the specified music is recorded. Based on the read time information, the system controller 9 searches the place where the highest interval of the indicated music is recorded by a scan controller 11 and repeatedly reproduces a range of a time (t) from the part where the highest interval of the specified music is recorded. Then a change in key is instructed from an operation key input 10 for the voice which is repeatedly reproduced, and then the system controller 9 controls an audio controller 4 to select a proper key for the music which is varied in interval. |
