DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a singing range analysis method for karaoke software with a main melody represented by data in an electronic musical score format.

[0002]

2. Description of the Related Art A karaoke apparatus processes karaoke software for a karaoke song specified by a user and outputs karaoke accompaniment music as sound. The karaoke software is managed in association with a song number for identifying a karaoke song, and when a song number is designated by the karaoke apparatus, the karaoke software is subjected to a reproduction process and accompaniment music is output as sound.

[0003] In many karaoke apparatuses, the data which is the main component of the karaoke software is composed of M notation in an electronic musical score format.
IDI data. MIDI uses the pitch (note number) and the accompaniment tones that make up the melody (instrument part) for each instrument.
It is described using note information indicating the size (velocity), note length (step time), sounding duration (gate time), and the like. In the MIDI karaoke software, an appropriate instrument (such as a flute) is assigned to a melody to be sung by a singer, and this instrument part is set as a main melody.
Note that the unit of time in MIDI is described by the number of beats instead of the absolute time. Specifically, the length corresponding to a quarter note is one beat, and one beat is described by the number of clock pulses of a predetermined cycle. The karaoke apparatus adjusts the tempo of the karaoke song by variably controlling the frequency of the clock pulse. By the way, the key may be different between the accompaniment music of a certain karaoke song generated by the karaoke apparatus and the accompaniment music of the song (original song) of the same title sung by the former singer. This is because the range where ordinary people can utter is lower or higher than the range where professional singers utter. Of course, for users who want to sing in the same range as the original song, the karaoke device has a key setting function that can shift the range of the entire accompaniment music, including the main melody, so that the original song range can be restored. "Song key setting value" is described in the karaoke table of contents.

[0004] In the karaoke table of contents, information such as a song name and a singer name is described in a song number for each song, and "+
The original music key set value of each music is described by numerical values such as “1”, “−1”, and “+2”. This numerical value indicates the difference in the sound range between the original song and the karaoke song. According to the notation, “+1” indicates that increasing the key setting value of the karaoke device by 1 results in the same sound range as the original song. . In addition,
When a key of the karaoke apparatus is operated to raise or lower the key set value by 1, the range of the accompaniment music is raised or lowered by one semitone.

[0005]

The above-mentioned original music key setting value is effective information for a person who wants to sing a karaoke music with the original music key. The user only needs to adjust the key setting value according to the table of contents. However, the singer's utterable range varies from individual to individual, and even if the original song key setting value is “+1”, “+2”
Some people sing more easily. Recently, many people know their own utterance range accurately and know how much the key set value should be adjusted for the range of the original music. In order for such a person to set the key corresponding to his / her vocal range from the above-mentioned original music key setting value, the key setting value should be adjusted to the original music key setting value, and the original music key setting value should be further changed. A two-step adjustment operation is performed in which the key set value is adjusted to match the singing range. In this case, the operation is complicated and troublesome.

[0006] Japanese Patent No. 2797648 discloses a technique of a karaoke apparatus that automatically adjusts key set values in accordance with the vocal range of a singer. In this karaoke apparatus, a singer performs a test utterance of a predetermined sound toward a microphone prior to singing, detects a range in which the singer can utter, and adjusts the specified karaoke music so as to match the detected utterance range. The key set value is automatically set. In addition, by notifying the singer of the changed key setting value, the next time the same song is sung, the singer may be adjusted to the notified setting value.

However, if all the persons present at the karaoke venue detect the utterance range, the time spent in the karaoke facility is wasted, and the person who has completed the detection operation will be unable to detect another person. The time required for the work is useless. Further, there is also an annoyance that the key setting value is memorized for each music. If the utterable range is changed by the practice, the notified set value is not always usable next time. In that case, it is necessary to perform the range detection operation again.

Therefore, the inventors of the present invention may publish information (key setting reference information) that can easily derive the optimum key setting value for each karaoke song based on the vocal range of the singer himself in the table of contents. I thought it was desirable. To do this, the range of the main melody of the song (song range) is analyzed in advance, and the data (singing range data) that is the source of the key setting reference information
Must be created. Therefore, an object of the present invention is to provide a method for analyzing the singing range of karaoke software in advance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As one embodiment of the present invention, MI
An example in which DI data is analyzed by a general-purpose personal computer, and as a result of the analysis, singing range data which is the origin of the key setting reference information described in a table of contents book or the like is created. A dedicated analysis program is installed in this computer, and an external storage such as a hard disk drive stores MI
It is assumed that DI data is stored. It should be noted that the present invention is not limited to a personal computer, and may be a dedicated analyzer.

The analysis program receives the designation of the music number, reads out the corresponding MIDI data, and acquires the note number and the gate time of the note constituting the main melody. Then, the gate times of the notes having the corresponding numbers are totaled for each note number, and a table associating the note numbers with the total gate time (total sounding time) is created as singing range data.

The created singing range data is stored in an appropriate storage resource in association with the corresponding music number from which the data was generated. FIG. 1 is a graph showing singing range data. This graph is a histogram (distribution diagram) in which the pitch described by the note number is associated with the total sounding time of the corresponding pitch, and the total number of beats is adopted as the total sounding time. The singing range data may be appropriately managed by, for example, storing it in a database serving as an original of the table of contents. Then, the singing range data may be processed into appropriate information (image data of a distribution map, etc.), and this may be published in the table of contents as key setting reference information. FIG. 2 (A)
(B) shows an outline of the key setting reference information published in the table of contents book. In addition to the items (song number, song name, singer, original song key, singing start) described in the general table of contents book, each note number of the lowest / highest pitch and the above-mentioned histogram (pitch distribution diagram) are keys. It is posted as setting reference information (A). In the margins of the page of the table of contents book or on a predetermined page, a correspondence explanatory diagram of note numbers and absolute pitches is published (B).

In the above embodiment, the highest and lowest pitches are obtained based on the singing range data. However, the highest and / or lowest pitches may be included in the singing range data.

The total sound generation time may be the total time (beat count) of the step times. Of course, not only the time but also the frequency of occurrence of the corresponding note for each pitch can be used as the singing range data.

[0019]

According to the singing range analysis method of the present invention, singing range data is created by analyzing karaoke software described in the electronic musical score format. If this singing range data is represented by appropriate information such as texts and graphs, and the information is posted in a table of contents, the singer can accurately grasp the singing range of each song. When singing in the vocal range of, the karaoke apparatus can be adjusted to the optimal key setting value.

If the highest pitch or the lowest pitch is included in the singing range data, it can be published as it is in the table of contents. As a result, the singer obtains reference information for adjusting the key setting value to the optimum value in accordance with his or her utterable range.

If the singing range data includes a data table in which the frequency of occurrence of a note corresponding to each pitch is included,
It can be easily converted to a histogram graph. If this histogram is included in the table of contents, the singing range can be visually confirmed.

In addition, the singer may be able to utter even in a sound range exceeding the limit of his vocal range for a moment, and if the number of samples outside the vocal range is small in the histogram, the singer can set the key. It can be determined that the user can sing with the original music key set value without adjusting the value. Conversely, if the number of samples near the limit of the vocal range is large even within the vocal range, the singer's optimal key setting value could be adopted.

Further, if a data table in which the total sounding time of the corresponding pitch is associated with each pitch is included in the singing range data, a graph representing the total sounding time for each pitch can be drawn. In this graph, even if the frequency of appearance of a note at a certain pitch is high, the shorter the note length of the note, the shorter the singing time of the singer at that pitch. Therefore, information for each pitch is described in more detail. In particular,
The detailed information about the pitch near the limit of the vocal utterance range is reference information for strictly adjusting the key set value.
