instrument or voice in the top box above and see what appears. You might even try entering a form (Sonata, Variations...), an ensemble (Trio, SATB, Orchestra...), a style (Ragtime, 12-tone), or even a poet or a country... The text in [Square Brackets] at the end of each line tells you which button to click back on the home page to find a full description of each work.
There is even a difficulty rating - try entering "dif-x" where x equals a number between 1 and 4. A rating of 1 means a talented beginning performer can negotiate the piece, a rating of 4 suggests that only a professional should attempt it. (P.S. entering a blank field will give you a complete list of works.)
