Dr. Joseph Krush presents new Dodecaphonic Tonal sets and leads readers through Expanded Diatonicism, Nonaphonic and Decaphonic Bi-modality, culminating with "The World's Best Dodecaphonic Tonal Set." He illustrates Semi-Modulation through Rotating Quintcircles. Relative Compatibility of Keys and Chromatic Clashes of Tones are also explored. Composers will benefit from this groundbreaking new system. Krush addresses the question: "What kind of a tonal system would result if the major and minor modes were combined into one, fused major/minor key?" His ultimate answer is: "Uni-tonal Nonaphonic Bi-Modality." Covering topics including Nonaphonic, Tri-Tonal, Bi-Modal Systems, Hendecaphonic and Dodecaphonic Systems, and Dodecaphonic Tonality and Functionality, the book is divided into two parts and spans 25 chapters.

Joseph is a lifetime pianist, organist, music theorist, and music arranger. He has been playing Christmas Carols on piano since the 1960s and on organ since the 1970s. The arrangements made public in 2024 are the culmination of these years of playing plus ten years of compiling, arranging, and editing the 75 best Christmas Carols that he has encountered since 1960. They are arranged for piano and organ, to be played as solos or duets or as accompaniments.
