  FIG. 2 is a block diagram illustrating a hardware configuration example of a sound value changing device (computer) according to the embodiment of the present invention. The sound value changing device is composed of, for example, a personal computer. A central processing unit (CPU) 202, ROM 203, RAM 204, network interface 205, input device 206, output device 207, and external storage device 208 are connected to the bus 201.

  The CPU 202 performs data processing or calculation and controls various components connected via the bus 201. The ROM 203 stores a control procedure (computer program) of the CPU 202 in advance, and is started when the CPU 202 executes the computer program. A computer program is stored in the external storage device 208, and the computer program is copied to the RAM 204 and executed. The RAM 204 is used as a work memory for data input / output, transmission / reception, and temporary storage for control of each component. The external storage device 208 is, for example, a hard disk storage device or a CD-ROM, and the stored content does not disappear even when the power is turned off. The CPU 202 executes the computer program in the RAM 204 to perform processing of the sound value changing device.

  The network interface 205 is an interface for connecting to a network such as the Internet. The input device 206 is, for example, a keyboard and a mouse, and can perform various designations or inputs. The output device 207 is a display, a printer, or the like. 4A to 4C and the screens of FIGS. 5 to 7 are displayed on the display in the output device 207.

  FIG. 1 is a block diagram for explaining the functions of the computer program. The sound value changing device (method) is realized by the computer executing the computer program. The note value changing device (method) 100 includes a storage means (step) 101, a magnification specifying means (step) 102, a change method specifying means (step) 103, a sound value changing means (step) 104, and a score changing means (step) 105. Display means (step) 106, pre-change audition means (step) 107, and post-change audition means (step) 108.

  4A to 4C are diagrams showing examples of musical scores displayed on the display in the output device 207. FIG. 4A shows a musical score before changing the note value (length) of the note and / or rest, and FIGS. 4B and 4C show a musical score after changing the note value of the note and / or rest.

  The storage means 101 stores score data including a plurality of note data and / or rest data. As shown in FIG. 4A, the display unit 106 displays the musical score data before change stored in the storage unit 101.

  FIG. 4B shows an example in which the time signature is changed in accordance with the change in note value of notes and / or rests. The magnification designating unit 102 designates the magnification for changing the note value of the note data and / or rest data, for example, to ½ in accordance with a user instruction. Moreover, the change method designation | designated means 103 designates the change of a time signature according to a user's instruction | indication. When the user instructs execution of the note value change, the note value change unit 104 performs a plurality of note data and / or pauses stored in the storage unit 101 at a magnification of 1/2 times designated by the magnification designation unit 102. Change the note value of note data. For example, a quarter note is changed to an eighth note, and a quarter rest is changed to an eighth rest. When the note value is changed by the note value changing unit 104, the score changing unit 105 changes the time signature in the score data stored in the storage unit 101. For example, the time signature is changed from 4/4 time to 4/8 time. Thereby, the time signature coincides with the time signature of each measure, and the score can be changed to a correct score.

  For example, the magnification specifying means 102 can specify four magnifications of 1/4, 1/2, 2 and 4 times. In this case, the note value changing means 104 only needs to change the type of note data and / or rest data.

  When changing the time signature, the score changing means 105 first changes the denominator of the time signature, and when it becomes the target time signature, determines the time signature. For example, when the note value of a 3/4 time signature is halved, the time signature is 3 / (4 × 2) = 3/8 time. If the target time signature is not reached, the time signature numerator is subsequently changed to match the target time signature. For example, when the note value of a 2/2 time score is quadrupled, the time signature is set to 4 × 2/2 = 2 × 2/1 = 4/1 time signature.

  FIG. 4C shows an example in which the position of the bar line is changed in accordance with the change in note value of notes and / or rests. The magnification designating unit 102 designates the magnification for changing the note value of the note data and / or rest data, for example, to ½ in accordance with a user instruction. Further, the change method designating unit 103 designates the change of the bar line position in accordance with a user instruction. When the user instructs execution of the note value change, the note value change unit 104 performs a plurality of note data and / or pauses stored in the storage unit 101 at a magnification of 1/2 times designated by the magnification designation unit 102. Change the note value of note data. For example, a quarter note is changed to an eighth note, and a quarter rest is changed to an eighth rest. When the note value is changed by the note value changing unit 104, the score changing unit 105 changes the position of the bar line in the score data stored in the storage unit 101. For example, the position of the bar line is changed so that the time signature of each measure matches the 4/4 time signature of the time signature. One bar in FIG. 4C corresponds to two bars in FIG. Thereby, the time signature coincides with the time signature of each measure, and the score can be changed to a correct score.

  When changing the position of the bar line, when changing the note value to 1/4, three bar lines are deleted for every four bar lines of the original score. When the note value is changed to 1/2, one bar line is deleted for every two bar lines of the original score. When the note value is changed to twice, a bar line is added at a half of each bar. When the note value is changed to 4 times, bar lines are added at three positions of 1/4, 1/2, and 3/4 of each bar.

  FIG. 5 is a diagram showing an example of a sound value change screen. When the user instructs to change the sound value using the mouse in the input device 206, the display unit 106 displays the sound value change screen in FIG. 5 on the display in the output device 207.
