Music performance assisting system for teaching sequential use of fingers, method used therein and information storage medium for computer program representative of the method

A music performance assisting system associated with a music instrument having plural manipulators manipulated by a player for producing tones, comprising;

• a memory for storing pieces of data information representative of a series of notes and rests forming a tune;
• a divider for dividing said series of notes and rests into plural groups each having at least one note;
• a finger assignor selectively assigning said at least one note of each group to fingers of each hand of said player in accordance with rules of fingering for determining candidates of a use of fingers;
• an evaluator evaluating said candidates of said use of fingers on the basis of criteria for a desirable fingering so as to select said use of fingers from said candidates;
• and
• a guide for teaching said use of fingers along said tune to said player, in which said finger assignor determines a note pattern of a predetermined number of notes from a start of said tune and assigns a first finger pattern to said note pattern before determining said candidates.

A method for teaching a use of fingers along a tune to a player, comprising the steps of:

• a) storing pieces of data information representative of a series of notes and rests forming a tune and rules of fingering;
• b) dividing a series of notes and rests representative of a tune into groups each having at least one note;
• c) selectively assigning said at least one note of each group to fingers of each hand of said player in accordance with said rules so as to obtain candidates of a use of fingers;
• d) repeating said steps b) and c) until the end of said tune, if necessary;
• e) evaluating the candidates of said use of fingers on the basis of criteria for a desirable fingering so as to select said use of fingers from said candidates;
• and
• f) teaching said use of fingers to said player,
• wherein at least one first sub-candidate of a finger pattern and second sub-candidates of a finger pattern are respectively assigned to a note pattern having a predetermined number of notes counted from a start of said tune and remaining notes on the basis of a relation between said note pattern and said remaining notes so as to prepare said candidates in said step c).

An information storage medium for storing a computer program representative of a method for teaching a use of fingers along a tune to a player, said method comprising the steps of:

• a) storing pieces of data information representative of a series of notes and rests forming a tune and rules of a fingering;
• b) dividing a series of notes and rests representative of a tune into groups each having at least one note;
• c) selectively assigning said at least one note of each group to fingers of each hand of said player in accordance with said rules so as to obtain candidates of a use of fingers;
• d) repeating said steps b) and c) until the end of said tune, if necessary;
• e) evaluating the candidates of said use of fingers on the basis of criteria for a desirable fingering so as to select said use of fingers from said candidates;
• and
• f) teaching said use of fingers to said player,
• wherein at least one first sub-candidate of a finger pattern and second subcandidates of a finger pattern are respectively assigned to a note pattern having a predetermined number of notes counted from a start of said tune and remaining notes on the basis of a relation between said note pattern and said remaining notes so as to prepare said candidates in said step c.
