Welcome to Wikipedia. We appreciate your contributions, but in one of your recent edits to Piano Sonata No. 2 (Rachmaninoff), it appears that you have added original research, which is against Wikipedia's policies. Original research refers to material—such as facts, allegations, ideas, and personal experiences—for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. You can have a look at the tutorial on citing sources. Thank you. Materialscientist (talk) 07:48, 27 February 2023 (UTC)
