Abstract
The present invention is a chord teaching system and method which assists the organist in learning musical chords. The system functions in several different modes and the various modes are selected by the learning organist. The chord teaching system enables the learning organist to select a chord without demonstrating any knowledge of the correct finger position on the keyboard of the organ necessary to play the chord. The system, depending upon the mode of operation, plays the chord selected and indicates to the learning organist the key corresponding to the root note of the selected chord or indicates to the organist the keys corresponding to the notes of the selected chord or enables the organist to depress the keys that the organist believes form the selected chord and indicates a correct response if the organist depresses the proper key and indicates the correct keys that form the notes of the chord if the response is incorrect. In addition, the learning organist can store into the system's memory a sequence of chords for later playback. In one mode of operation, the root note of each chord in the stored sequence is indicated to the organist who must correctly depress a key corresponding to the root note in order to sound the chord and advance in sequence to the next stored chord. In another mode of operation, the notes forming each chord in the stored sequence are indicated to the organist who must correctly depress keys corresponding to the notes in order to advance in sequence to the next stored chord. In yet another mode of operation, the stored chords are sounded at times under control of the rhythm unit of the organ and the keys corresponding to the sounding chord are indicated to the organist.
