1. a music difficulty level calculation apparatus, there is storage unit (14), the tone data that this cell stores comprises the pitch information of each note forming melody, fortune when pressing this note key refers to information and the temporal information about this note, is characterized in thatHave:

  • Indivedual difficulty computing unit (CPU11,401 ~

         403), it refers to any one of information and temporal information according to described pitch information, fortune, calculates indivedual difficulty about each of multiple key elements of performance necessity of melody;

    WithAll difficulties computing unit (CPU11,404), it calculates the difficulty of melody according to each indivedual difficulties calculated by this indivedual difficulty computing unit;

    Described indivedual difficulty computing unit has;

    Fortune refers to difficulty computing unit, and it refers to information according to described pitch information and fortune, and the fortune that the fortune calculating the note key adjoined about pressing refers to refers to difficulty;

    Rhythm difficulty computing unit, it, according to the temporal information about described note, calculates the rhythm difficulty about the length of this note and the timing of note;

    WithTonality difficulty computing unit, it, according to the pitch information about described note, calculates the tonality difficulty of the tonality about this melody,Described fortune refers to that difficulty computing unit has;

    First classification item value acquisition unit, it obtains classification value about at least one classification item in four kinds of classification values, described four kinds of classification values are respectively;

    about the first classification item of the position of finger when relating to the adjacent note key of pressing, represent the first classification value of the concrete form in this classification item;

    About the second classification item of the break condition of the finger related to when pressing adjacent note key, represent the second classification value of the concrete form in this second classification item;

    Refer to about relating to wearing or across the 3rd classification item referred to, represent the 3rd classification value of the concrete form in the 3rd classification item;

    And about the 4th classification item of changing finger related to when pressing adjacent note key, represent the 4th classification value of the concrete form in the 4th classification item, andFirst cost summing elements, it is in each classification item described, according to the classification value in described classification item, from store for the described concrete form described classification item value at cost, in cost table in described storage unit, obtain the value at cost for the described concrete form in described classification item, this value at cost cumulative, obtains described cumulative value at cost as the difficulty referred to about described fortune simultaneouslyWherein, described all difficulty computing units, the multiple indivedual difficulty calculated by described indivedual difficulty computing unit each on be multiplied by weighting coefficient, calculated the difficulty of melody entirety by cumulative indivedual difficulties of having paid weight, store the difficulty calculated in the memory unit.
