Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a performance reproducing apparatus, and more particularly to a performance reproducing apparatus which can easily and quickly find a music desired by a user from a large number of stored music with a simple structure.

[0002]

2. Description of the Related Art In a karaoke machine or a personal computer having music reproduction software built-in, there are times when it is desired to select and reproduce a desired song from a large number of stored songs.
As a selection method, for example, there is a method of inputting a song title, a composer, a singer name (a performer's name), a genre, etc., and searching for a song by using these inputs as search conditions.

Further, in Japanese Patent Laid-Open No. 5-197374, a part of each song stored, for example, 1 from the beginning of the song.
0 seconds or 1 from the position after a certain time has passed from the beginning
By automatically playing the music data for 0 seconds in sequence, you can search for a desired music from a large number of stored music without pressing the skip key for each music. A device has been proposed.

Further, Japanese Patent Laid-Open No. 2001-125583 proposes an electronic music data search / listening device that reproduces a part of the lyrics of a song searched under a predetermined search condition. This electronic music data search / listening device partially reproduces before and after the electronic music data that matches the keyword used for the search.

[0005]

When many search conditions such as the song name, composer name, and singer name are satisfied, the method of inputting the search conditions and searching for songs is to narrow down the songs sufficiently. Yes, it is valid. However, the search conditions are not sufficient, and many songs still exist as candidate songs even after the search.

The performance reproducing apparatus described in the above-mentioned Japanese Patent Laid-Open No. 5-197374, when selecting a music piece, sequentially reproduces a fixed position common to each music piece, such as the beginning of the music piece or after a certain time has elapsed from the beginning. Therefore, the played part does not always include the characteristic phrase of the song, that is, the so-called chorus part, and even if you listen to that part, you cannot recognize what the song is, and it often takes time to select the song. .

Further, since the electronic music data search / listening device disclosed in the above-mentioned Japanese Patent Laid-Open No. 2001-125583 reproduces a part before and after the keyword, an appropriate part is viewed depending on the selection of the keyword. You can, but you must pay attention to the choice of keywords.

The present invention has a strong impression on many people.
Focusing on the characteristic phrase that is a typical part of the song, the so-called chorus part, even if multiple candidate songs are selected as a result of searching the stored songs by condition setting, only the characteristic phrases of those candidate songs By continuously playing back one after another, the user can easily and quickly find the song he or she really wants. Also, without specially storing the characteristic phrase itself, a simple configuration with a small storage capacity is required. It is an object of the present invention to provide a playing / playback device that enables this.

The first feature is that the apparatus comprises a trial listening means for sequentially reproducing only the musical piece data corresponding to the address, the absolute address, or the number of measures.

Further, the present invention stores music data of a plurality of pieces of performance music, and music data / characteristic phrase position storage means for storing a command instructing a position of each characteristic phrase of the plurality of pieces of performance music data, and Among the plurality of pieces of music piece data, music piece search means for searching the piece of music piece data satisfying a predetermined condition, and among the pieces of music piece data searched by the piece of music piece search means, the piece of music data / characteristic phrase position storage means are stored. A second feature is that the apparatus further comprises a trial listening means for sequentially reproducing only the musical piece data specified by the command.

Further, according to the present invention, in the case where the trial listening means sequentially reproduces the musical composition data, the tempo is corrected so that each musical composition can be reproduced at a high speed at a constant rate with respect to the tempo of the individual musical composition. There is a third feature.

A fourth feature of the present invention is that the audition means controls the release speed of a musical sound produced during high-speed reproduction or the length of reverberation added to the musical sound to be short.

Further, the present invention further comprises a necessary / unnecessary input means and a judging means for judging whether or not it is the last selected music piece based on the input of the necessary / unnecessary input means. Based on the input of the required / unnecessary input means when the trial listening means is sequentially reproducing the retrieved musical piece data,
A fifth characteristic is that the judging means judges whether or not it is the last selected music piece.

Further, according to the present invention, when there is no instruction input by the necessary / unnecessary input means within a fixed time during which the performance data searched by the music search means is being reproduced by the trial listening means, the judging means is provided. Is the point at which it is judged that the reproduction of the performance music data is unnecessary and proceeds to the reproduction to the next performance music data.
There is a feature of.

According to the first to eighth characteristics, even if a plurality of candidate music pieces are selected as a result of searching the stored music pieces by setting the conditions, only the characteristic phrases of the candidate music pieces are successively consecutively selected. The user can easily and quickly find the music that he / she really wants, and the characteristic phrase is stored as a command in the address of the music data storage means, the number of measures, or the music data to be played. Therefore, it can be realized with a simple configuration having a small storage capacity.

Further, according to the third and fourth characteristics, in particular, the characteristic phrase can be reproduced at a higher speed than in the normal performance reproduction, so that the music desired by the user can be found at a higher speed.

Further, in particular, according to the fifth and sixth characteristics, since the next performance music data can be sequentially reproduced without the input by the necessary / unnecessary means or the input for a predetermined time, the desired music can be easily and quickly performed. Can be selected.
