This is a collection of pieces for learners, written by Tansman in 1946 during his stay in America. The currently available Eschig edition (published in 2008) is essentially a reprint of the first edition by the formerly allied American company, Associated Music Publishers (AMP). While the current edition features both English and French texts, the English title is the original. It consists of ten short pieces, varying in tempo; the fast pieces are characterized by a neat and concise Neoclassical style, while the slow pieces are composed in a refined Romantic or Impressionistic style, imbued with a mellow mood. Although its clear sense of tonality makes it suitable for learners, the overall difficulty is rather high, requiring a technical level comparable to Czerny's Op. 299 (School of Velocity). In terms of difficulty, it corresponds to the final volumes (Volume 4) of works like Bartók's For Children and pedagogical collections for young pianists, and includes passages comparable in difficulty to Tansman's general piano works. In lessons, it is well-suited as a supplementary collection for learners who have progressed to the level of the Sonata Album. As it contains many brilliant pieces, it would also be suitable for recitals and concert performances. Furthermore, "Diversion" is synonymous with "Divertimento," meaning something akin to "amusement" or "diversion." Following the common practice in Japan of referring to Benjamin Britten's Concerto for Piano Left Hand and Orchestra, Op. 21, as "Diversions," the title here is also rendered as "Diversion."
