PURPOSE:To naturally improve the ability to learn 'listening' more by enjoying a questioning/answering game of even chords as to the music device on which a user answers the same tone as a sounded tone by key operation. CONSTITUTION:An electronic musical instrument sounds a reference scale 'do, re, mi, fa, so, la, si, do' after a message 'What tone is this?'. Then the electronic musical instrument sounds a chord as a question and the user listens to it and presses respective keys judged to have the same pitches as the respective constituent sounds of the chord within 20 seconds. Consequently, when the constituent sounds of the questioned chord match the respective answer sounds of the keys operated by the user, a message 'correct', for example, 'do, mi, so', having the same pitches as the correct sounds, and 'next question' are outputted and a next chord is questioned. |
