The intelligent accompaniment generating system includes an input module, an analysis module, a generation module and a musical equipment. The input module is configured to receive a musical pattern signal derived from a raw signal. The analysis module is configured to analyze the musical pattern signal to extract a set of audio features, wherein the input module is configured to transmit the musical pattern signal to the analysis module. The generation module is configured to obtain a playing assistance information having an accompaniment pattern from the analysis module, wherein the accompaniment pattern has at least two parts having different onsets therebetween, and each onsets of the at least two parts is generated by an algorithm according to the set of audio features. The musical equipment includes a digital amplifier configured to output an accompaniment signal according to the accompaniment pattern.

An accompaniment sound generating device includes a specifier, an accompaniment sound generator, and an accompaniment sound outputter. The specifier specifies a plurality of musical performance parts for which accompaniment sounds are generated based on an input musical performance sound. The accompaniment sound generator generates the accompaniment sounds that belong to the plurality of specified musical performance parts for each musical performance sound. The accompaniment sound outputter outputs the accompaniment sounds generated for the plurality of musical performance parts with timing for generating the accompaniment sounds aligned with timing for generating musical performance sounds.

An automatic accompaniment apparatus including a determiner that determines a current position in a music piece in progress, a selector that selects an accompaniment element data set to be used out of a plurality of accompaniment element data sets every time the determined current position arrives at a predetermined switching position, an accompaniment data generator that generates accompaniment data indicating automatic accompaniment based on the selected accompaniment element data set, a calculator that calculates time information corresponding to a time required until the determined current position arrives at a next switching position, and a display controller that controls a display to display arrival advance notice information indicating the calculated time information.
