Music is an outlet for self-expression. It has the power to influence your feelings, connect you to others and break down barriers ... And believe it or not, it's science -- a LOT of science! The tunes that move us are a blend of science, technology, engineering and mathematics, plus passion and emotion. In this book, you'll find out when humans began making music, the early history of recording and playing back, how things we use every day like headphones and streaming services were created, and what's in store for the future of music technology. Along the way, you'll be introduced to playlists featuring must-listen songs and a look at the psychology of music, including why you like the music you like and why you can't get some songs out of your head. A fresh, engaging and relevant look at an art form that we all love.
