为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
为便于理解，以下对本申请涉及的名词做出解释：
音乐筛选界面：是指呈现于用户面前，用于进行音乐筛选和/或结果显示的程序界面。
二维坐标系：是指在同一平面上有公共原点的两条数轴构成的坐标系，通常具有两个维度。
音乐属性：乐器经过敲击、摩擦、吹奏等方式发出的声音和/或人的声音形成音乐。音乐属性是指形成的音乐中所具有的特殊性质，主要涉及两方面，分别 是音乐的旋律特征、音乐中使用的乐器的类型。
属性标签：是指根据前述音乐属性，对音乐进行分类后标注的分类标记。一个音乐至少具有一个音乐属性的属性标签，一个音乐的一个音乐属性所具有的属性标签的个数不限。比如，一个音乐具有节拍和乐器类型两类音乐属性的属性标签，其中的乐器类型属性具有琵琶、古筝和萧三个乐器类型的属性标签。
本申请实施例提供了一种音乐筛选方法，通过在二维坐标系上进行的触发操作，显示筛选出的目标音乐，减少了用户进行音乐筛选的时间和步骤，给予用户根据模糊需求进行音乐筛选的可能性，增强了用户的体验感。
示意性的如图1所示，音乐筛选界面110上显示有二维坐标系111，比如该二维坐标系111是直角坐标系，响应于二维坐标系111上的触发操作，显示目标音乐。
示意性的，音乐筛选界面110上显示有搜索栏控件和二维坐标系111。用户可以在搜索栏控件中进行输入操作，通过输入关键信息实现音乐筛选；或者，用户通过在二维坐标系111上的点击操作进行音乐筛选。以二维坐标系111是直角坐标系为例，用户在直角坐标系中的某一坐标点上进行双击操作，程序界面从音乐筛选界面110跳转到音乐播放界面120。在音乐播放界面120上显示有歌曲“歌曲A”，该歌曲处于播放状态。也即，用户在直角坐标系上进行双击操作后，直接播放目标音乐。
音乐的筛选过程中，通过用户与终端进行人机交互确定筛选出的目标音乐。通常情况下，用户需要借助筛选工具，通过筛选工具上进行的操作，确定所需要的音乐，终端根据用户操作显示目标音乐。本申请实施例提供了一种基于二维坐标系的音乐筛选交互方案，通过用户在二维坐标系上的触发操作，显示筛选出的目标音乐，可以满足用户的模糊筛选需求。

步骤304可包括：
响应于极坐标系上的触发操作，获取触发位置的半径坐标和方位坐标；

示意性的，如图4a所示，二维坐标系411是极坐标。其中，第一维度是半径维度，第二维度是方位维度，滑动按键412所在位置即为触发操作的触发位置。根据图4a所示，半径维度对应节拍属性，方位维度对应音阶属性。以节拍维度分为慢节奏、次慢节奏、一般节奏、次快节奏、快节奏的五个节拍等级，音阶维度分为音阶一、音阶二、音阶三、音阶四、音阶五、音阶六、音阶七的七个音阶等级为例，响应于滑动按键412处的点击操作，获取滑动按键412所在位置的半径坐标为一般节奏，方位坐标为音阶四；将一般节奏确定为滑动按键412所在位置在半径维度的坐标，将音阶四确定为滑动按键412所在位置在方位维度的坐标。

示意性的，如图4a所示，响应于音乐筛选界面410中极坐标系上的触发操作，显示目标歌曲和目标歌单，其中目标歌曲包括“歌曲1”和“歌曲2”，目标歌单包括“歌单1”和“歌单2”，该目标歌曲和目标歌单所属的程序界面是音乐筛选界面410。
可选的，音乐筛选界面上还可以显示目标音乐的其他显示元素，比如，音乐筛选界面上显示出部分候选音乐的相关信息。示意性的，如图4b所示，在滑动按键412滑动至该坐标点时，在滑动按键412所在的位置的周边显示候选音乐的列表项，列表项内包括“歌曲1”、“歌曲2”、“歌单1”和“歌单2”；另外，用户还可以通过触发“…”展开列表项，比如，点击“...”展开列表项。响应于音乐筛选界面410中极坐标系上的触发操作，比如双击操作，在音乐筛选界面410的底部显示音乐播放控件，同时播放歌曲1。
示意性的，步骤306包括如下步骤：
根据触发位置在第一维度的坐标，确定第一属性标签；
根据触发位置在第二维度的坐标，确定第二属性标签；
在音乐库中筛选出第一音乐属性具有第一属性标签，且第二音乐属性具有第二属性标签的第一音乐，作为目标音乐，第一属性标签和第二属性标签是不同的属性标签。
属性标签是指，根据音乐属性对每个音乐进行分类后标注的分类标记。示意性的，一个音乐至少具有一个音乐属性的属性标签，一个音乐的一个音乐属性所具有的属性标签的个数不限。比如，音乐1具有慢节奏、音阶二、音阶三、古筝、琵琶四个属性标签，其中慢节奏属于节拍属性的属性标签，音阶二和音阶三属于音阶属性的属性标签，古筝和琵琶属于乐器类型属性中的弹奏乐器类型的属性标签。
音乐库是指用于储存音乐相关信息的数据库，音乐库中至少包括一个候选音乐。终端通过在音乐库中进行音乐的筛选，最终确定筛选出的目标音乐。示意性的，音乐库可以保存在本地数据库中，或者保存在云端数据库中，或者是在本地数据库和云端数据库中均有保存。比如，终端首先在本地数据库中的音乐库1进行筛选后，未找到目标音乐；随后，终端在云端数据库中的音乐库2进行筛选后找到目标音乐。
触发位置在二维坐标系中对应一个坐标点，通过该坐标点可以获取到对应的两个不同的音乐属性的属性标签。也即，根据触发位置在第一维度的坐标得到第一属性标签，根据触发位置在第二维度的坐标得到第二属性标签。依据第一属性标签和第二属性标签，终端可以在音乐库中筛选出至少一个目标音乐，并将目标音乐进行显示。示意性的，根据获取到的第一属性标签和第二属性标签，终端在音乐库中筛选出第一音乐，第一音乐的第一音乐属性具有第一属性标签，第二音乐属性具有第二属性标签。
示意性的，如图5所示，二维坐标系511是直角坐标系，用户在直角坐标系上进行触发操作的位置是滑动按键512所在的位置。响应于直角坐标系上的触发操作，获取触发操作的触发位置为(-2等级节拍，1等级音域)。根据触发操作的触发位置，可以确定，触发位置的第一属性标签为-2等级节拍，第二属性标签为1等级音域。终端在音乐库中进行筛选，找到歌曲“歌曲A”具有“-2等级节拍”、“音阶三”、“1等级音域”、“钢琴”、“古筝”的属性标签，终端将歌曲“歌曲A”确定为目标歌曲，并从音乐筛选界面510跳转音乐播放界面520显示歌曲“歌曲A”。
在音乐筛选的过程中，并非任何时候均能筛选出第一音乐。因此，本申请实施例提供的音乐筛选方法中，在不存在第一音乐的情况下，步骤306还包括如下步骤：
在所述音乐库中筛选出第二音乐作为所述目标音乐，其中，所述第二音乐的第一音乐属性所具有的属性标签与所述第一属性标签的距离最近，所述第二音乐的第二音乐属性具有所述第二属性标签；或，在所述音乐库中筛选出第三音乐作为所述目标音乐，其中，所述第三音乐的第一音乐属性具有所述第一属性标签，所述第三音乐的第二音乐属性所具有的属性标签与所述第二属性标签的距离最近；或，在所述音乐库中筛选出第四音乐作为所述目标音乐，其中，所述第四音乐的第一音乐属性所具有的属性标签与所述第一属性标签的距离最近，所述第四音乐的第二音乐属性所具有的属性标签与所述第二属性标签的距离最近。
示意性的，第一音乐属性具有的属性标签与第一属性标签的距离是指，第二音乐的第一音乐属性所具有的属性标签与第一属性标签的距离。其余的距离的定义与之类似，在此不再赘述。在音乐筛选界面中，根据第一音乐属性和第二音乐属性确定的第一维度和第二维度构成二维坐标系，在二维坐标系中至少存在一个坐标点对应有一个候选音乐。示意性的，该距离可以是通过二维坐标系中的数学坐标点之间的距离决定的，或者是根据其他预设的距离比较规则决定的。
比如，在直角坐标系中，触发位置的坐标为(1，2)，候选音乐的坐标为(3，5)，则第一属性标签为1，第二属性标签为2，依据数学坐标点的距离计算方法，候选音乐的第一音乐属性与第一属性标签的距离为2，第二音乐属性与第二属性标签的距离为3。
又如，在极坐标系中，触发位置的坐标为(快节奏，音阶五)，候选音乐的 坐标为(快节奏，音阶一)，则第一属性标签为快节奏，第二属性标签为音阶五，根据预设的音阶距离比较规则，候选音乐的第一音乐属性具有第一属性标签，第二音乐属性与第二属性标签的距离是四个音阶。
综上所述，本申请实施例提供的音乐筛选方法，通过在二维坐标系上进行的触发操作，可以显示筛选出的目标音乐，实现了音乐的模糊筛选，减少了用户进行音乐筛选所耗费的时间和精力，使得筛选出的目标音乐能够满足用户的模糊筛选需求。
示意性的如图6所示，本申请实施例提供了一种在音乐库中对候选音乐标记属性标签的方法，以及一种生成二维坐标系的方法。该方法的执行主体为计算机设备，例如，为运行有音乐类应用程序的终端，如图2中的终端220，方法包括如下步骤：
步骤601：根据音乐属性，标记音乐库中的各个候选音乐的属性标签。

属性标签是指根据音乐属性，对每个音乐进行分类后标注的分类标记。一个音乐至少具有一个音乐属性的属性标签，一个音乐的一个音乐属性所具有的属性标签的个数不限。
音乐库中包括有至少一个候选音乐，终端在进行音乐筛选时，将根据触发位置获取到的第一属性标签和第二属性标签，与音乐库中的候选音乐的属性标签进行匹配。因此，需要对音乐库中的各个候选音乐的每个音乐属性均需要进行属性标签的分类。
示意性的，如图7所示，可以采用旋律定位技术作为标记属性标签的基础，根据候选音乐的音频波形信息，运用测频的方法，基于音高显著度进行旋律提取，获取相关音乐属性的信息。旋律识别技术的执行主体为计算机设备，例如，为运行有音乐类应用程序的终端，如图2中的终端220，包括如下步骤：
步骤701：对输入的音乐内容进行预处理。
步骤702：对预处理后的音乐内容进行时频变换及谱处理。
步骤703：通过音高显著度函数进行计算。
步骤704：对音高进行跟踪。
步骤705：旋律定位。
通过时频变换及谱处理，将预处理后的音乐内容转化为频率信息，再通过音高显著度函数对频率信息进行计算，将频率信息计算为不同的音高，对不同的音高进行跟踪，最终实现旋律定位。
示意性的，标记属性标签的基础还可以是其他分类方法和/或技术，比如简单加权方法。
根据音乐属性进行的属性标签的标记，可以有多种标记规则，以下仅为本申请提供的几种示例性实施例，终端可根据实际需要进行调整：
1、标记节拍属性的属性标签。
在音乐属性包括节拍的情况下，步骤601包括：

维度字符串用于生成二维坐标系，通过在维度字符串上的触发操作实现。根据前述内容，二维坐标的第一维度对应第一音乐属性，第二维度对应第二音乐属性，因此，维度字符串的数量不小于音乐属性的数量，且至少包括两个音乐属性对应的字符串。比如，维度字符串包括字符串“节拍”、字符串“音阶”、字符串“音调”、字符串“曲式”、字符串“打击乐器”、字符串“键盘乐器”、字符串“吹奏乐器”。

又如，第一维度字符串是字符串“打击乐器”，第二维度字符串是字符串“音域”。双击字符串“打击乐器”生成x轴维度，双击字符串“音域”生成y轴维度，由此生成直角坐标系。
又如，第一维度字符串是字符串“曲式”，第二维度字符串是字符串“音调”。拖动字符串“音调”到指定位置生成半径维度，拖动字符串“曲式”到指定位置生成方位坐标，由此生成极坐标系。

步骤801：服务器进行歌曲录入。
服务器对音乐库中的各个候选音乐进行音乐属性的分类，并标记各个候选音乐的属性标签，将标记后的歌曲进行录入。服务器一方面将分类资源上传至云端数据库，以便后续的再次归类、多次筛选和数据调用；一方面将属性标签的数据保存在本地数据库，以便终端随时调用。
步骤802：终端生成二维坐标系。
步骤803：终端向服务器发送第一维度和第二维度的相关信息。
步骤804：服务器进行二维坐标系解析。
根据选择功能界面上显示的至少两个维度字符串，用户依据自身需要从中选择两个维度字符串，分别生成第一维度和第二维度，终端根据第一维度和第二维度生成二维坐标系。
服务器接收到终端发送的二维坐标系中的第一维度和第二维度，进行二维坐标系解析。服务器根据第一维度和第二维度，调用音乐库中的数据，音乐库保存在云端数据库和/或本地数据库中。服务器将符合第一维度和第二维度的候选音乐导入到二维坐标系中，保证二维坐标系中存在至少一个坐标点对应一个候选音乐。
步骤805：终端在二维坐标系上进行触发操作。
步骤806：终端向服务器发送触发位置的坐标。
响应于二维坐标系上进行的触发操作，终端获取到触发操作的触发位置，并将触发位置的坐标发送至服务器，也即，将触发位置在二维坐标系上的第一维度的坐标和第二维度的坐标发送至服务器。
步骤807：服务器进行音乐筛选。
步骤808：服务器向终端发送筛选出的目标音乐。
步骤809：终端显示目标音乐。
服务器获取到触发位置的坐标后开始进行音乐筛选。服务器依据触发位置的坐标在音乐库中进行搜索，在搜索到第一候选音乐后，判断第一候选音乐的第一音乐属性与触发位置在第一维度的坐标是否匹配，以及第二音乐属性与触发位置在第二维度的坐标是否匹配。若不匹配，则以触发位置的坐标为中心在二维坐标系的范围内向四周扩大搜索。
在服务器搜索到匹配的候选音乐后，也即搜索到目标音乐，服务器向终端发送筛选出的目标音乐，终端对目标音乐进行显示。
综上所述，本申请实施例提供的音乐筛选方法，通过对候选音乐的属性标签进行标记，将每个候选音乐的音乐属性进行细化分类，使得音乐筛选的依据更为 准确，降低了音乐的筛选粒度。另外，本申请实施例提供的音乐筛选方法，通过提供维度字符串的方式，使得用户可以根据自己的需求选择二维坐标系的维度，也即，用户可以根据自己的需求进行特定音乐属性的模糊筛选，满足了用户的使用需求，一定程度上增强了用户的使用体验感。
