(Explained). The circle of fifths is a familiar tool known by many
musicians. Although this device usually receives nothing more than a
brief explanation in most music theory books, the circle illustrates the
foundation that organizes much of Western tonal music and is therefore
essential to grasp. With the novice musician in mind, author Dan Maske
expounds on the nature, nuances and applications of the circle of fifths
throughout this book, exploring topics such as: intervals, keys and key
signatures, scales, chords and chord progressions, and more.
