Right Playing - Wrong Playing basically includes a blue and a red book, each with scores, as well as two blue and two red CDs, and an answer key to the exercises. The repertoire comprises passages from classical works: orchestral music, choral music, chamber music, songs with accompaniment, and piano pieces recorded by a.o. Aarhus Symphony Orchestra and the Danish National Vocal Ensemble (DR VokalEnsemblet).
The challenge, then, is to listen to the music with errors on the red CDs, and find the discrepancies in the BLUE BOOK, where the correct scores are to be found, or, vice versa, to listen to the music in the correct version on the blue CDs, and find the errors in the RED BOOK, where these same errors are incorporated into the scores themselves. Where was the error? What was wrong? What were the musicians playing when not playing what is written? Right Playing - Wrong Playing! The mistakes correspond to varying levels of difficulty. These may be further adjusted by makinguse of the clues associated with each exercise, which are designed to give helpful information.
Right Playing - Wrong Playing is essentially intended to be used as a basis for self-study. However, it may also be used in class at educational institutions, with each exercise potentially serving as a piece of homework.
