The art of embellishment is the knowledge and use of musical ornamentation. This is an old art and many volumes have been written on this craft. Some
ornaments[?] are the
trill,
mordent[?],
arpeggio, and
grace note.Ther are many, many others. Each nationality and historical period have used intrinsically specific
ornamantation[?], thus, the embellishment of a
J.S. Bach piece is more than likely not appropriate for a piece written by
Chopin; this is for two reasons notwithstanding that the piano is to be used for the Chopin instead of the organ or harpsichord: Bach is a composer of the 18th century Baroque in Germany, and Chopin a Polish/French composer of the 19th century. Very different times, very different nationalities.
