Running parallel to the 7th HLF, the Heidelberg Laureate Forum Foundation (HLFF) presents the exhibition "La La Lab – The Mathematics of Music" in Heidelberg. Music and Mathematics share many similarities as fields of study. Both disciplines are abstract, have structures and manipulation rules, a well-defined notation, and are absolutely precise in their results. Working on them requires practice and an analytical mind. It is no surprise that Mathematics and Music are closely related. But their relationship goes far beyond an analogy. Mathematics is infused deeply in all aspects of Music, from the physics of sound to the crafting of instruments, from rhythmic patterns to tonal harmony, from classical to electronic music. Mathematics supports Music and our understanding of Art the same way as it supports Physics and our understanding of the World. Hearing music with mathematical ears brings to the music lover understanding, appreciation for details, and a greater enjoyment of the art; and to the professionals the ability to compose and perform, and tools to express their creativity. Conceived in collaboration with world renowned experts, "La La Lab - the Mathematics of Music" mixes a laboratory format with interactive exhibits to present visitors with the historical, conceptual, and philosophical connections between mathe- matics and music: from the centuries-old tools that musicians use for composing, to the most current research that pushes the boundaries of musical creativity and mathematical knowledge.
