参见图1，图1为本申请实施例所提供的一种Midi音乐文件的生成方法的流程图，该方法包括：
S101：获取待配置音乐的曲谱数据，并确定所述待配置音乐相应的弹奏乐器；
本步骤旨在获取待配置音乐的曲谱数据，以及用户所需要弹奏的弹奏乐器。曲谱数据指记录音乐音高或者节奏的各种书面符号的有规律组合，常见的简谱、五线谱和吉他谱等均可以作为本实施例中的曲谱数据，该曲谱数据主要包括各曲谱的和弦，还可以包括每分钟的节拍数(beat(ing)per minute，英文缩写BPM)等。待配置音乐可以为用户准备弹奏的音乐，或者由用户指定的音乐等。此外，在确定弹奏乐器时，还可以确定该弹奏乐器的弹奏节奏型，用于后文确定弹奏力度。本步骤的弹奏乐器主要指弦乐器，包括但不限于尤克里里、吉他等等。
和弦指法数据表包含和弦与对应弹奏所使用的指法，以及弹奏时不弹的弦等数据。参见图2，图2为本申请实施例所提供的部分和弦及对应指法示意图，其中包含了Em、G和C三个和弦，则可以直接查找和弦弹法 数据表，从而确定和弦的指法。
容易理解的是，本实施例默认在执行本步骤前该和弦指法数据表已经存在，可以在执行本实施例的前述步骤中生成，也可以在执行本实施例的前述步骤中获取得到，还可以在执行本实施例前已经完成和弦指法数据表的生成或者获取过程。在此对于如何生成或者获取该和弦指法数据表不作具体限定，其主要包括和弦名、指法和不弹的弦三部分内容构成。下表1为图2对应三种和弦的和弦指法数据表：
表1和弦指法数据表
Figure PCTCN2022127590-appb-000001
当然，表1仅为部分和弦对应的和弦指法数据表，本领域技术人员有能力根据确认不同弹奏乐器在不同弹奏节奏型下，各种和弦对应的指法操作。换言之，本领域技术人员有能力在执行本步骤时查询和弦指法数据表确定任一种和弦的指法。
在本步骤的一种具体实施过程中，可以由用户输入待配置音乐的曲谱数据和弹奏乐器，或者根据用户输入内容解析以得到或者确定上述内容。例如用户输入待弹奏的歌曲名称，可以自行根据歌曲名称获取相应的曲谱数据，并提供推荐弹奏乐器供用户选择，也可以提供该曲谱数据相应的弹奏节奏型或者提供可弹奏乐器供用户选择。容易理解的是，不同乐器对应的弹奏节奏型可能存在差异，在此不一一举例限定。
S102：根据所述弹奏乐器的弦数确定所述Midi音乐文件中的音轨数量；
本步骤旨在确定音轨数量，通常弹奏乐器的弦数与所需音轨数量相同， 例如吉他对应六条音轨，而尤克里里对应四条音轨。
可以实现配置一定数量的音轨，则在执行本步骤时根据弹奏乐器的弦数确定所需要占用的音轨数量，并配置该音轨为相应的弹奏乐器。
在本步骤的另一种执行方式中，也可以在确定弹奏乐器的弦数后，配置与弦数相同数量的音轨。
S103：读取所述曲谱数据中的和弦，调用节奏型数据表确定所述弹奏乐器对应和弦的弹奏弦号；
本步骤旨在确定曲谱数据中和弦的弹奏弦号。节奏型数据表包含了和弦和对应的弹奏弦号，以及每个弦号的弹奏时长。需要说明的是，同一和弦采用不同的弹奏类型，其对应的弹法存在差异。参见表2和表3，表2为指弹节奏型中部分和弦与相应弹法的节奏型数据表，而表3则是扫弦节奏型中部分和弦与相应弹法的节奏型数据表：
表2指弹节奏型中部分和弦与相应弹法

表3扫弦节奏型中部分和弦与相应弹法
Figure PCTCN2022127590-appb-000003
Figure PCTCN2022127590-appb-000004
由表2和表3可以看出，C和弦在不同的弹法节奏型中的弹法存在差异，因此，本步骤需要读取曲谱数据中的一个和弦，在节奏型数据表中，根据其弹法找到这一拍和弦对应的弹奏弦号。例如，若曲谱数据中的第一拍，和弦为C和弦，在表3中，查找到对应的弹奏弦号为扫5、4、3弦，持续时间为一拍。此外，以表3中C和弦为例，第一拍C和弦需要弹5弦4弦3弦，若连续两个C和弦，则后续需要弹三次，分别为4弦3弦2弦1弦0.5拍，4弦3弦2弦1弦0.25拍，1弦2弦3弦4弦0.25拍，共同构成第二拍的C和弦。
S104：根据所述弹奏弦号查找所述和弦指法数据表，确定所述和弦对应的指法；
本步骤需要根据上一步骤中确定的弹奏弦号查找和弦指法数据表，从而确定该和弦对应的指法。
此外，还需要注意的是，和弦指法数据表包含了和弦和对应指法的映射关系，意即所有包含和弦和对应指法的映射关系均可作为本步骤中的和弦指法数据表，其存在形式并不拘泥于表格形式，可以以数据库或者其他便于检索的数据格式存在。
S105：根据所述指法确定所述和弦对应的音阶，并按照和弦顺序确定由音阶构成的音阶序列；
本步骤旨在确定指法对应的音阶序列，具体需按照上文所述过程确定每个和弦对应的指法，进而确定该指法对应的音阶，如此确定所有和弦对应的音阶后，按照曲谱数据中和弦顺序即可得到音阶序列。需要说明的是，每个和弦按照上述过程可得到对应的音阶，而音阶序列对应曲谱数据中的所有和弦，即和弦与音阶相对应，而曲谱数据与音阶序列相对应，且每个和弦为一拍。
在执行本步骤时，可以根据弹奏乐器的音阶数据表确定相应的音阶数据表，且不同弹奏乐器的音阶数据表存在较大差异。以吉他为例，参见图3，图3为本申请实施例提供的吉他指板音阶数据表示意图，其中包含了弦号、品号和对应音阶的关系，例如图3中，1弦0品对应高音3，而1弦1品对应高音4，2弦0品对应中音7，由于指法包含了弦数和品数，则本步骤可以对照音阶数据表确定各和弦的音阶，进一步按照和弦的弹奏顺序确定曲谱数据包含所有和弦对应的音阶序列。
S106：确定所述音阶序列中各节拍的弹奏方式，将所述音阶序列及对应的所述弹奏方式写入各个音轨，得到所述Midi音乐文件。
本步骤旨在确定各节拍的弹奏方式，主要指弹奏力度以及每个节拍的弹奏次数。首选需要确定各节拍的弹奏方式，可以根据曲谱数据的每分钟节拍数确定弹奏强弱规律，曲谱数据中每小节的第一拍称为强拍，其余带强音的单位拍称为次强拍，不带强音的单位拍称为弱拍，而有强有弱的相同的时间片断按照一定的次序循环重复叫做节拍，节拍的单位称为拍子。而构成节拍的相同时间片段称为单位拍。如两拍的节拍，单位拍用四分音符标识，可称为四二拍子。常见的几种曲谱数据的每种节拍数和对应的弹奏强弱规律如下：
2/4拍——每小节只有两拍，弹奏强弱规律为：强、弱。
3/4拍——每小节只有三拍，弹奏强弱规律为：强、弱、弱。
4/4拍——每小节只有四拍(但可以被二整除)，弹奏强弱规律为：强、弱、次强、弱。
6/8拍——每小节只有六拍(但可以被二整除)，弹奏强弱规律为：强、弱、弱、次强、弱、弱。
而弹奏次数因弹奏节奏型的不同而异，例如强拍可能需要弹一次、两次或者四次等。弹奏节奏型指弹奏乐器时的弹法或者手法，包括但不限于扫弦节奏型、指弹节奏型等等。此后即可根据弹奏强弱规律和每个拍子对应的弹奏次数确定音阶序列中各节拍的弹奏力度。下文以两种不同的弹奏节奏型对如何确定音阶序列中各节拍的弹奏方式进行说明：
若弹奏节奏型为指弹节奏型，其包括如下步骤：
第一步、根据所述弹奏强弱规律确定每个拍子第一次弹奏的弹奏力度；
第二步、将每个拍子的剩余弹奏次数均设为弱拍对应的弹奏力度。
由于每个拍子可能需要弹奏多次，而在指弹节奏型中，无论该拍节奏需要弹奏多少次，其第一次与弹奏强弱规律相对应，后续剩余弹奏次数均设为弱拍的弹奏力度。例如若强拍需要弹奏2次，则按照强→弱弹奏该强拍，而若需要弹奏4次，则按照强→弱→弱→弱弹奏该强拍。
又例如，若弹奏节奏型为扫弦节奏型，其弹奏力度的确定方式与指弹节奏型并不相同。此时按照如下过程执行：
第一步、根据所述弹奏强弱规律确定初始弹奏力度；
第二步、以预设节拍数为周期，在每个所述周期内从所述初始弹奏力度开始，所述音阶序列中各音阶的弹奏力度递减，且各所述音阶弹奏的开始时间递增。
对于扫弦节奏型而言，其初始弹奏力度有强弱规律的第一拍的强弱决定。由于扫弦过程多根弦同时弹奏，则后续每个节拍的弹奏力度递减，均小于第一拍的弹奏力度，且音阶弹奏的开始时间递增。
为了更清楚的描述两种不同弹奏节奏型确定弹奏力度时的区别，下文引入弹奏力度值作为参考，可以先获取节拍力度值表。在节拍力度值表中，不同的弹奏力度，例如强拍、次强拍和弱拍，均包含相应的弹奏力度区间。一般来说，8个力度强度对应0-127共计128个弹奏力度值，数值越大，弹奏力度越大。当然，本领域技术人员还可以采用其他方式表示弹奏力度，在此不一一举例限定。
在获取节拍力度值表后，根据弹奏强弱规律确定拍子每次弹奏时的节拍强度，根据节拍力度值表确定节拍强度对应的弹奏力度值，最后建立弹奏力度值与拍子的弹奏次数的映射关系，得到音阶序列中各节拍的弹奏力度。逐一确定每个拍子的弹奏力度值后，即可得到该节拍的弹奏力度，进一步确定包含节拍的音阶的弹奏力度，最后即可得到包含所有音阶的音阶序列的弹奏力度。
若选择指弹节奏型，为了使得Midi音乐文件更符合实际弹奏规律，对于4/4拍节奏，其力度程度的变化规律为强→弱→次强→弱，则弹奏力度 可以按照80→40→60→40的循环行进，表明强拍对应的力度值为80，弱拍对应的力度值为40，而次强拍对应的力度值为60。若为3/4拍节奏，其变化规律为强→弱→弱，相应的可以按照80→40→40的弹奏力度循环进行。
若选择扫弦节奏型，设第一音阶为强拍，且同样力度值为80，假设各节拍采用相同递减，且力度值每次递减10，则弹奏时的力度值变化为80→70→60→50。
以音阶序列为<1,3,5>为例，音阶1，对应音轨5，可以设初始弹奏力度是80,时间0毫秒；音阶3，对应音轨4，力度70，时间1毫秒；音阶5对应音轨3，力度60，时间2秒，其余音轨的力度设置为0。还需要说明的是，每个周期内力度之间的差值不固定，但为了输出的声音更接近弹奏原声，每个周期内相邻音阶的力度差值可以设为固定值，如上述设定，在每个周期内相邻音阶的力度差值即为10。
可以看出，本实施例需要针对曲谱数据中的每个和弦，均可以按照上文所述过程确定其音阶和弹奏方式，则针对曲谱数据中所有和弦执行上述步骤后，可以得到曲谱数据对应的完整音阶序列。在具体的实施过程中，可以采用并行线程对曲谱数据中的各和弦分别执行上述过程，也可以在每个步骤中，对曲谱数据中的所有和弦均处理后再进入下一步骤，还可以对曲谱数据分段处理等，在曲谱数据中所有和弦均按上文所述过程执行并得到音阶序列及弹奏方式的前提下，任何并行处理方式或者串行处理方式均应在本申请的保护范围内。
最后，将音阶序列号和相应的弹奏力度写入各音轨，即可得到Midi音乐文件。可以看出，该Midi音乐文件至少应当包含音阶序列和对应的弹奏力度。此外，针对同一曲谱数据，若采用不同的弹奏乐器，可以配置多个Midi文件，也可以在该Midi文件的显示界面中配置弹奏乐器的选项，供用户选择。相类似的，针对不同的弹奏节奏型、曲谱数据的调式等参数亦可配置选项，供用户选择，则此时该Midi文件可以包含不同弹奏节奏型时的音阶序列及弹奏力度等。为了便于用户快速了解该曲谱数据，还可以将每分钟节拍数、曲谱数据的拍号和弹奏节奏型等相关参数添加至Midi 音乐文件。
本申请实施例通过生成Midi音乐文件，包含了弹奏乐器对应的指法、弹法、音阶和相应的弹奏力度，便于弹奏者知晓各和弦的弹奏方式，从而按照Midi音乐文件稳定弹奏速度，加快和弦切换速度，快速掌握各种弹奏技巧，以及弹唱结合，有效帮助乐器演奏者练习。

在上述实施例的基础上，作为优选的实施例，调用节奏型数据表确定弹奏乐器对应和弦的弹奏弦号之前，可以根据弹奏乐器弹奏时的节奏型，建立各弹奏乐器对应的节奏型数据表。
本实施例旨在建立节奏型数据表，需要注意的是，本实施例仅要求该节奏型数据表的建立在调用节奏型数据表确定弹奏乐器对应和弦的弹奏弦号执行前完成即可，而对于该建立过程与上一实施例中前述步骤之间的顺序关系不作具体限定。在构建节奏型数数据表时，针对不同弹奏乐器建立相应的节奏型数据表。
在上述实施例的基础上，作为优选的实施例，根据弹奏弦号查找和弦指法数据表，确定和弦对应的指法之前，可以整合弹奏乐器弹奏和弦时的指法，生成和弦指法数据表。
本实施例旨在建立和弦指法数据表，同样需要注意的是，本实施例仅要求该和弦指法数据表的生成过程在对和弦指法数据表查表执行前完成即可，而对于该建立过程与上一实施例中前述步骤之间的顺序关系不作具体限定。
特别的，可以实现构建节奏型数据表和和弦指法数据表，作为Midi音乐文件生成的基础数据库存于Midi音乐文件的生成设备或者云端数据库，从而能够在生成Midi音乐文件时快速调用，提高Midi音乐文件的生成效率。
