The Mystery of Chopin's Préludes. Ashgate Publishing, 2015.
"...an effulgent example of stellar research and eloquent writing... a uniquely interdisciplinary examination of Chopin's Preludes that never ceases to hold one's attention... a persuasive and carefully structured argument... engrossing... an extraordinary musical discovery... astonishing... a strikingly original achievement... highly recommended for pianists and piano teachers, for music libraries, and for academic libraries serving music programs." (Music Reference Services Quarterly, March 2016)
"The Mystery of Chopin’s Préludes provides valuable insights into our structural and aesthetic understanding of Chopin’s preludes. Leikin presents a compelling case that the Dies Irae enshrouds Chopin’s preludes, thereby infusing these 'tone-painting reflections of Lamartine’s poem' with an aesthetic of death. Leikin’s systematic illustration of the Dies Irae motive establishes this book as a definitive resource about Chopin’s preludes for performers, scholars, and listeners." (Notes, June 2016)
“The rich, well-elaborated context… The meticulous motivic analysis is impressive… really a great discovery… Most stunning of all is the cultural panorama… At some moments, it is even as if this is not a twenty-first-century author writing, but an intellectual from Chopin’s milieu who survived the composer……the book is written in the form of a musicological detective story… Each new chapter strikes with the unexpectedness of its approaches and received data… The book is a piece of musicological artistry.” (Min-Ad: Israel Studies in Musicology Online, Vol. 13, 2015-16)
The Performing Style of Alexander Scriabin. Ashgate Publishing, 2011.
"Carefully written, filled with interesting sidelights, and rich in detail... Highly recommended." (Choice, December 2011)
"Leikin provides a wealth of important observations based on his analyses of Scriabin's performance practice... meticulous and groundbreaking study... the prose is of high quality, very readable and clear, and the insights into Scriabin performance that Leikin provides are numerous and special... Leikin's achievement here is undeniably significant." (Notes, June 2012)
"Ambitious and thoroughly researched book... thorough, groundbreaking work..." (Slavonic and East European Review, July 2012)
