Abstract

Performance data for a musical instrument having note designating keys are provided representing a sequence of notes which constitute a length of musical performance. The performance data are analyzed, and based on the analyzed performance data, fingering data are then created representing fingers to be used for operating keys among the note designating keys to designate the respective ones of the sequence of notes. Fingering hand image data are then created representing fingering hand images including fingers to be used for operating keys for the sequence of notes. Finally, a display screen exhibits the fingers to be used for the sequence of notes based on the fingering image data. The screen displays a musical score, a range of keyboard and fingering hand profiles. The size of the fingering hand is preferably made different between the indication of key depressions and the indication of key release.

a finger image depicting a shape of a finger to be placed between the note designating a key corresponding to a note to be played in said range of the keys and said shape of the hand based on said fingering data.

3. An apparatus for creating fingering guidance as claimed in claim 1, further comprising:

a performance data advancing module which advances said performance data for analysis according to progression of the performance.

4. An apparatus for creating fingering guidance as claimed in claim 1, wherein said fingering data creating module analyzes said performance data fraction by fraction of said length of musical performance and creates said fingering data for every fractional length of said musical performance, said analysis and creation needing a certain length of time for said fractional length of the musical performance;

the apparatus further comprising;

a delaying module which delays said performance data for said fractional length of said musical performance by an amount of time equal to said certain length of time needed; and

a tone signal generating module which generates tone signals for said fractional length of said musical performance based on said delayed performance data.

5. An apparatus for creating fingering guidance as claimed in claim 1, wherein said fingering image creating module creates a first type of fingering data which represents a first type of finger image having a first length and not having a nail mark to be exhibited for indicating a note designating key to be depressed, while said fingering image creating module further creates a second type of fingering data which represents a second type of finger image having a second length which is greater than said first length and having a nail mark to be exhibited for indicating a note designating key to be released.

6. An apparatus for creating fingering guidance as claimed in claim 5, wherein said fingering image creating module further creates a third type of fingering data which represents a third type of finger image having a third length which is greater than said first length and is less than said second length to be exhibited a predetermined time length in advance to the exhibition of said first type of finger image and to the exhibition of said second type of finger image.

7. A method for creating fingering guidance in playing a musical instrument having note designating keys, the method comprising:

a step of providing performance data representing a sequence of notes which constitute a length of musical performance;

a step of creating fingering data representing fingers to be used for operating keys among said note designating keys to designate the respective ones of said sequence of notes based on analysis of said performance data;

a step of creating image data representing fingering images which include said fingers to be used for operating keys for said sequence of notes; and

a step of displaying said images of the fingers to be used for said sequence of notes based on said image data.

8. A method for creating fingering guidance as claimed in claim 7, wherein each of said fingering images includes:

a key range image depicting a range of said note designating keys;

a hand image depicting a shape of a hand to be located at a position as determined based on said performance data representing a note to be played among said sequence of notes and on said fingering data; and

a finger image depicting a shape of a finger to be placed between the note designating a key corresponding to a note to be played in said range of the keys and said shape of the hand based on said fingering data.

9. A method for creating fingering guidance as claimed in claim 7, further comprising:

a step of advancing said performance data for analysis according to progression of the performance.

10. A method for creating fingering guidance as claimed in claim 7, wherein said step of creating fingering data analyzes said performance data fraction by fraction of said length of musical performance and creates said fingering data for every fractional length of said musical performance, said analysis and creation needing a certain length of time for said fractional length of the musical performance;

the method further comprising;

a step of delaying said performance data for said fractional length of said musical performance by an amount of time equal to said certain length of time needed; and

a step of generating tone signals for said fractional length of said musical performance based on said delayed performance data.

11. A method for creating fingering guidance as claimed in claim 7, wherein said step of creating image data creates a first type of fingering data which represents a first type of finger image having a first length and not having a nail mark to be exhibited for indicating a note designating key to be depressed, while said step of creating image data further creates a second type of fingering data which represents a second type of finger image having a second length which is greater than said first length and having a nail mark to be exhibited for indicating a note designating key to be released.
