On average, it takes about five hours to read (but more to fully absorb) so it isn't a huge time commitment. Dedicate only a few hours to reading this book and gain a lifetime of skills that will give your music that professional edge. We wrote this book because we were tired of all of the "songwriting" websites / books that talk vaguely about "finding your inspiration", or rhyming lyrics, or some other soft, non-actionable component of creating music. With Hooktheory I, we created an approachable, intuitive resource that concretely answers the hard questions: Why do certain chords fit together easily, and others not so easily? How can I get from this chord to that chord? How can I create a great melody? It's a book that will make you say "ah ha." many times over.
