Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a musical score input method for an electronic computer.

[0002]

2. Description of the Related Art A conventional technique will be described with reference to FIG. In FIG. 7, 901 is a musical score indicating pitch, 902
Indicates the note length menu (902-1) and rest menu (902-2), 903 indicates the dotted menu, 904
Is a menu of accidentals. As discussed in Japanese Patent Laid-Open No. 62-275893, the conventional musical score input method is that after selecting a note of a desired length from a menu of notes and rests (902) with a pointing device such as a mouse, The method was to select the pitch of the note you want to input on the staff notation (901) and then enter the note length and pitch separately.

When inputting a dotted note, after selecting a note of a desired length from the menu of notes and rests (902) and selecting a dot from the menu of dotted symbols (903). , The pitch of the note you want to input on the staff notation (901)
It was a method of selecting and inputting notes.

In addition, when inputting an accidental symbol such as sharp or flat, after selecting a note that has already been input,
The method was to select and set an accidental from the accidental menu (904). Or, on staff notation (90
In this method, the vertical axis of 1) was associated with the chromatic scale of the keyboard, and the pitch of the desired note was entered simultaneously with the accidental.

[0005]

In the above conventional method,
In order to input a single note without a dot or accidental, it was necessary to perform two operations of setting the duration and the pitch of the note. In addition, when setting a dot symbol and an accidental symbol, each operation had to be performed. Further, in the method of setting the accidental by associating the vertical axis on the staff with the chromatic scale of the keyboard, it is not possible to input a very fine score, for example, the sharpness of the re and the flat of the Mi cannot be distinguished.

An object of the present invention is to provide a musical score input method capable of inputting the pitch and duration of a note with a single operation.

Another object of the present invention is to provide a musical score input method capable of inputting the pitch and duration of a note and accidental symbols with a single operation.

Another object of the present invention is to provide a musical score input method capable of inputting a pitch and a length of a pitch and a dotted symbol with one operation.

[0009]

As a pointing device of the score inputting means, a mouse provided with, for example, a button is used to move a cursor to a desired position on the staff and press the mouse button. For example, to set sharpness, move the cursor while holding the button above the screen and release the mouse button when the preset threshold is exceeded. If you want to set the dotted symbol, move the cursor to the right side of the screen while holding down the button and release the mouse button when the preset threshold is exceeded.
Further, the above-mentioned object is achieved by setting the length of the sound according to the time from when the mouse button is pressed until it is released.

[0010]

[Operation] A method of inputting a musical score by a pointing device having buttons, by moving the cursor to a desired position on the staff and then pressing the button, and holding the button and moving the cursor horizontally and vertically, then pressing the button. Try to separate them. With this, the pitch, length, presence / absence and types of accidental symbols, and dotted symbols can be set with one operation using the time during which the button is pressed and the cursor position when the button is pressed and released. Presence and type can be set.
