The findings of this book are drawn from a conference held in 2013 in Kaunas, Lithuania, titled "Music and Technologies 2", which provided a continuous discussion on the interdisciplinary music research developing currently at such important forums as the CIM (Conference on Interdisciplinary Musicology) and the ISMIR (International Society for Music Information Retrieval). This book consists of a collection of articles written by musicologists and musical performers, sound engineers, and educators from Europe and the USA. Leading contemporary ideas in the field of music technologies are explored, as are some aspects of the cognition of classical and contemporary music.
