This book explores the fundamentals of computer music and functional programming through the Haskell programming language. Functional programming is typically considered difficult to learn. This introduction in the context of creating music will allow students and professionals with a musical inclination to leverage their experience to help understand concepts that might be intimidating in more traditional computer science settings. Conversely, the book opens the door for programmers to interact with music by using a medium that is familiar to them. Readers will learn how to use the Euterpea library for Haskell (http://www.euterpea.com) to represent and create their own music with code, without the need for other music software. The book explores common paradigms used in algorithmic music composition, such as stochastic generation, musical grammars, self-similarity, and real-time interactive systems. Other topics covered include the basics of signal-based systems in Haskell, sound synthesis, and virtual instrument design.

'The selection of material is coherent and satisfying, and the book would be suitable for anyone with an interest in computer music, regardless of programming background.'

'Paul Hudak was both a world-leading functional programmer, and skilled jazz musician. This book brings together his two passions, by using Haskell as a domain-specific language for describing music. The result is a fascinating study in how computer science can illuminate art, and art can illuminate computer science.'

Simon Peyton Jones - Microsoft Research

'This book is a joy. It should be in the library of every Haskell programmer and every musicologist interested in the underlying mathematics of music. Conceived and written by Paul Hudak, it was brought to fruition by Donya Quick. A fitting tribute to Paul and his lifetime's interests in both Haskell and music.'

Richard Bird - University of Oxford

'Programming is the most direct and unrestricted way to tell computers how to behave and what to produce. With this book, the reader will not only learn, step by step, a modern programing language in Haskell, but will also understand how such a language can be tuned towards application in music. This legacy of Paul Hudak is one of the most vibrant and decisive calls for popularizing programming techniques as a new and powerful medium for the arts.'
