 Rimsky-Korsakov later credited this work as a great influence on him as a composer; it also supplied a vast amount of musical material from which he could draw for future projects, either by direct quotation or as models for composing fakeloric passages.The second project was the editing of orchestral scores by pioneer Russian composer Mikhail Glinka (1804–1857) in collaboration with Balakirev and Anatoly Lyadov.Glinka's sister, Lyudmila Ivanovna Shestakova, wanted to preserve her brother's musical legacy in print, and paid the costs of the project from her own pocket.
