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.
