Rendition style determining apparatus detects at least one of duration
of a first note to be performed at a given time point and time interval between
the first note and a second note to be performed following the first note, in order
to automatically impart music piece data with an appropriate rendition style. Rendition
style to be imparted to the music piece data in relation to the given time point
is determined on the basis of the detected duration or time interval. Also, the
apparatus can readily control the rendition style to be imparted to the music piece
data, by appropriately setting/changing rendition style determination conditions,
such as reference time lengths. Music piece data is supplied to a determination
device, thereby causes the determination device to perform automatic rendition
style determination based on the supplied music piece data and then displays the
rendition style imparted to the music piece data.
