The 中项 and manner by which a 人类 may 交互 with a 机 for the purpose of 樂/乐 制作 has 证明 an area of immense 研究 and 活动 since the days of early 电子 乐器 This 术语 is used without any great consistency in part due to the immense scale of current 研究 and 活动 in the 领域(野外)

Any conceivable 中项 of inputting 数据 into a 系统 to elicit some 形(曲)式 of 乐 meaningful 响应/反应 may be considered to be a 控制器 In the 最广泛 可能 感觉 a 控制器 via some 形(曲)式 of 通讯 between 组成 parts e g 樂器數界/乐器数字接口 converters 算機/计算机 软件 in conjunction with some 中项 of producing or modifying 声波 may be termed an 交互 乐器 经常 such 控制器 存在 in homologous 关系 with 传感器 e g of 动作 Thus gloves conductors batons toys amongst countless other examples may be constructed or 改 to 功能(函数) as 樂/乐 乐器

An 现有 形(曲)式 of 樂/乐 乐器 may be 改 through the addition of 传感器 enabling 控制 of additional 电子 mediated 声波 生成 or 修正 包括 the instrumental 声波 itself in addition to the conventional 控制 the 樂者/乐者 exerts over the 制作 of the acoustic 声波 Such examples are also sometimes referred to as Extended 乐器
