* Our summary is short, simple and pragmatic. It allows you to have the essential ideas of a big book in less than 30 minutes. By reading this summary, you will discover a new approach to music, the different ways of listening to it and musical examples in the digital and instantaneous age. You will also learn : the different harmonic repetitions within a musical piece, from yesterday to today; how the surrounding space can be captured within a piece of music; what background music is and the importance of silence; how to listen to standards in the 2010's and the willingness of musicians to merge with music. With YouTube and the Cloud, it is now possible for us to have access to a multitude of music, from here and elsewhere. This digital musical richness also has its drawbacks: we often don't know what we are listening to. We have a general idea of it, at most, and stay on the surface. Spotify's algorithms, for example, propose a playlist based on nationality, age, etc., without trying to make the listener discover a real diversity. Yet there are many different artists, including Björk, Beyoncé, Arvo Pärt, The Beatles and John Coltrane. Although at first glance they have nothing in common, they can be brought together, not by assigning labels or using a specific vocabulary from the history of music, but by linking their music to each other, to you and to life. *Buy now the summary of this book for the modest price of a cup of coffee!
