Abstract: A musical instrument and a method for automatically playing a musical accompaniment by guiding smoother and easier chord patterns to play. The present invention indicates chord forms which realize smoothest fingering after analyzing a chord following the present chord to determine whether the present chord should employ a root position or an inverted position for the smoothest fingering. Another feature of the present invention is to indicate chord forms which are selected to realize less movement of the player's hand after analyzing the former chord to determine a chord position (root position or inverted position) of the present chord which is the closest to the former position.

Abstract: It is an object of the present invention to realize a musical instrument and a method for automatically playing a musical accompaniment with guiding smoother and easier chord patterns to play. One of significant features of the present invention is to indicate chord forms which realize smoothest fingering after analyzing a chord following to the present chord to determine whether the present chord should employ a root position or an inverted position for the smoothest fingering. Another feature of the present invention is to indicate chord forms which are selected to realize less movement of the player's hand after analyzing the former chord to determine a chord position (root position or inverted position) of the present chord which is the closest to the former position.
