With the publication of the performance materials to the Mendelssohn Complete Edition, Breitkopf & Härtel is fulfilling its promise to release the conducting scores, parts and, in the case of well-known orchestral pieces, separate materials as soon as possible after the appearance of the respective volume in the Complete Edition. Breitkopf believes that all these important new scholarly findings should be made available directly to performers and taken into consideration in as many Mendelssohn performances as possible.
