The music and ideas of composer Arnold Schoenberg are central to many of the essays presented here. Schoenberg’s oft remarked upon masterpiece, Klavierstuck, Op.11, No.1, forms the focus of an entire section of the book. Four notable Schoenberg scholars of the younger generation revisit this seminal work on the eve of its centenary in order to reflect not only upon the work itself, but also upon the prodigious discourse that has surrounded it since nearly the date of its composition. More broadly, Schoenberg’s compositional and analytical concerns resonate through many of the other essays presented here, too. His concepts of “The Musical Idea” and “Developing Variation” are treated extensively in relation to the music of Anton Webern and Johannes Brahms, respectively. Musical Currents from the Left Coast will be of great interest to any individuals and institutions with an investment in the contemporary discourse of music theory and will be of special interest to scholars beyond that field who are also engaged with the work of Arnold Schoenberg.
