The first icon indicates that the used guitar chord of the music is included in the designated guitar chord, that is, the user can perform with his / her guitar chord. The second icon indicates that the specified guitar chord includes a transposed guitar chord obtained by transposing the used guitar chord of the music, that is, transposes the music or attaches a capo (capo tast) to the guitar. This indicates that the user can perform. The third icon is a case where neither the first icon nor the second icon is present, and indicates that the song cannot be played by the user or contains an unknown guitar chord. .

  In the display items, the unknown chord number is a numerical value indicating the number of guitar chords that are not used in the designated guitar chord among the guitar chords used in the music. For example, in the music on which the first icon is displayed, the number of unknown codes is 0 (zero). The user can select a song to be played with reference to these chord states and the number of unknown chords.

When a music is selected on this search result display screen (S104), a music confirmation screen corresponding to the type of the selected music (here, “by chord status” item) is displayed, and the user can view details of the music. While confirming, various designations can be made during performance. In the case where it is determined that only the guitar chord can be played in S105, that is, the music on which the first icon is displayed, the music confirmation screen shown in FIG. 7 is displayed.

  In FIG. 9, when “music is lowered by 3” is selected and the music is reserved, the music information corresponding to the music is played with the music lowered by 3. FIG. 11 shows a monitor screen during music performance in this case. Similar to the monitor screen of FIG. 8, a lyrics video and a guitar chord video are displayed on the background video. As the music information is played with the pitch lowered by 3, the guitar chord image is also displayed with the pitch lowered by 3.

  On the other hand, when the music is reserved by selecting “3 fret capo” in FIG. 9, the music information corresponding to the music is played without changing the original pitch, that is, the pitch. FIG. 12 shows a monitor screen during music performance in this case. The lyrics video and the guitar chord video are displayed on the background video, but the guitar chord video displays the finger chord name in the low chord, not the name of the guitar chord actually played. The displayed guitar chord name “D, E, A” is “F, G, C” in the performance with capo tasto attached to the 3rd fret.

As described above, when it is determined in S107 that the key can be changed and the performance is possible, the user can change the key to play the music information, or the user can perform the performance by attaching the capotast to the designated fret. Can be played with the specified guitar chord fingering.

  In the case of a song whose key has not been determined to be playable in S107, that is, a song on which the third icon is displayed, a song confirmation screen C shown in FIG. 13 is displayed. In this case, in addition to information related to the music, a tablature of the guitar chord that is not included in the specified guitar chord among the guitar chords used in the music is displayed, and the user needs to learn when playing the music It becomes possible to know the code and its fingering in advance. The user can also determine whether or not to play the music piece by checking the tablature. In the figure, two tablatures C7 and Asus4 are displayed.

  FIG. 14 shows a monitor screen during music performance in this case. Similar to the monitor screen of FIG. 8, a lyrics video and a guitar chord video are displayed on the background video. The music information is played on the MIDI sound source 26 without changing the pitch. Further, as shown in the figure, it is preferable to display a tablature of the guitar chord in addition to the guitar chord name in the lyrics video. In particular, by displaying the tablature for guitar chords not included in the designated guitar chord, the user can perform while confirming guitar chords that are not remembered.

  As described above, in the present invention, a guitar chord that a user knows or can play is designated as a designated guitar chord, and a database in which a guitar chord used for playing a guitar is stored in association with a song is searched. By doing so, the user can easily know music that can be played. In particular, in a music performance device that records a large number of music pieces such as a karaoke device, it is possible to select music that can be played from a large number of music pieces. Here, the embodiment in the case where the music search device is applied to the karaoke device has been described.
