Fingering display device and fingering display program

A fingering display device that performs fingering display on a screen by drawing a fingering moving image of playing a musical instrument at a reproduction time in a musical piece reproduction based on key pressing information of a musical piece, comprising:

• a musical sound/finger number information storage unit storing fingering information for performing the fingering display;
• a key pressing information generation unit that generates from the fingering information respective key pressing information at a plurality of different times including a time before the reproduction time and a time after the reproduction time;
• a fingering position information generation unit that generates fingering position information based on synthetic key pressing information obtained by synthesizing the respective key pressing information;
• a fingering image generation unit that generates a fingering image from the fingering position information, and
• a display device that displays a fingering image generated in the fingering image generation unit,
• wherein:
• the fingering position information is fingering position information calculated by interpolating:
• fingering position information at a start point time Ts of fingering at a time before the reproduction time;
• and
• fingering position information at an end point time Te of fingering at a time after the reproduction time, according to elapse of time from the time Ts to the time Te.

A fingering display program to perform fingering display on a screen by drawing a fingering moving image of playing a musical instrument in a musical piece reproduction based on playing information including respective musical sounds of a musical piece and corresponding finger numbers, wherein

• when generating a fingering drawing based on fingering position information corresponding to a reproduction time in the musical piece reproduction,
• the fingering display program makes a computer execute:
• setting,
• a time being a key pressing time after and closest to the reproduction time from a key releasing time when key pressing changes to key releasing at the reproduction time, and
• a time just before changing to key pressing information at the time;
• and
• generating fingering position information (Pm) so that shifting to a fingering position corresponding to the key pressing information at the time (T2) completes before the reproduction time (T) elapses a predetermined time from the time (T1), when a time period from the time (T1) to the time (T2) is longer than a desired time.

A fingering display program to perform fingering display on a screen by drawing a fingering moving image of playing a musical instrument in a musical piece reproduction based on key pressing information of a musical piece, wherein

• when generating a fingering drawing based on fingering position information corresponding to a reproduction time in the musical piece reproduction,
• the fingering display program makes a computer execute functions of:
• preparing a key pressing fingering image at the time of key pressing at the reproduction time, a key releasing fingering image at the time of key releasing just before the key pressing, and
• a dark-colored fingering shadow image;
• simultaneously displaying either the key pressing fingering image and the fingering shadow image or the key releasing fingering image and the fingering shadow image;
• and
• displaying the key releasing fingering image so as to increase an offset according to a sound volume at the time of the next key pressing with respect to the fingering shadow image.

A fingering display device that performs fingering display on a screen by drawing a fingering moving image of playing a musical instrument in a musical piece reproduction based on key pressing information of a musical piece, comprising:

• a musical sound/finger number information storage unit storing fingering information for performing fingering display;
• a key pressing information generation unit that generates key pressing information from the fingering information;
• a fingering position information generation unit that generates fingering position information from the key pressing information;
• a fingering image generation unit that, when generating a fingering image at a reproduction time in the musical piece reproduction from the fingering position information, prepares a key pressing fingering image at the time of key pressing at the reproduction time, a key releasing fingering image at the time of key releasing just before the key pressing, and a dark-colored fingering shadow image, simultaneously displays either the key pressing fingering image and the fingering shadow image or the key releasing fingering image and the fingering shadow image, and generates a fingering image with an offset image in which the key releasing fingering image is offset with respect to the fingering shadow image and displayed so that an offset increases according to a sound volume at the next key pressing time, and the offset is gradually changed according to a remaining time before the next key pressing;
• and
• a display device that displays fingering images generated in the fingering image generation unit.

A fingering display program to perform fingering display on a screen by drawing a fingering moving image of playing a musical instrument in a musical piece reproduction based on key pressing information of a musical piece, wherein

• when generating fingering images for the left hand and the right hand based on fingering position information corresponding to a reproduction time in the musical piece reproduction,
• the fingering display program makes a computer execute functions of:
• in a case where fingering images for the left hand and the right hand overlap, drawing foremost a hand corresponding to a musical sound whose sound production starting time is the latest among musical sounds as key pressing targets at a current reproduction position;
• and
• in a case where there is no musical sound as a key pressing target at a current reproduction position and neither of the hands presses a key, drawing foremost a hand including a finger that will press a key next.
