Abstract: Techniques for translating the harmony expressed by the keyboard playing of a performer into a chord type and root. Playing key pattern representations are stored in a digital memory at locations having addresses defining the corresponding chord type. A playing key pattern signal identifying the pattern of the keys played by the performer is then generated. The playing key pattern signal is used to locate the corresponding stored playing key pattern representation. When a match occurs, the chord type and root are derived by a processor.

Abstract translation: 用于将表演者的键盘演奏表达的和声转换成和弦类型和根的技术。 播放键图案表示在具有定义对应和弦类型的地址的位置处存储在数字存储器中。 然后产生识别表演者播放的键的图案的演奏键图案信号。 播放键模式信号用于定位相应的存储的播放键图案表示。 当发生匹配时，和弦类型和根由处理器导出。
