The invention is designed to provide a clear indication, for karaoke purposes, of the point at which a piece of music starts to build to a climax. To this end, the invention first relates warning period data, which is inserted in advance of the climax start position, to the music data and stores it in memory. This warning period data is subsequently read out and matched with the music data for input to a counter, which initiates a count immediately on receipt. At the same time, the warning period is divided into equal warning time intervals, the countdown of which provides a basis for the output of a message advising the user of how long remains before the climax start position.
