Physics of the blues—Scales, harmony, and the origin of blues piano styles

The development of the equal-temperament scale was driven, not by compromise, but by the need to extend the composer’s “palette” and increase the harmonic sophistication of western music. Many interesting musical idioms emerged from harmonic artifacts associated with equal temperament. In particular the blues “crushed-note” piano style resulted during the birth to the blues from the melding of this scale with the pure melodies and harmonies. In the presentation I will relate the history from a scientific perspective and illustrate with short keyboard performances. In homage to Kansas - the home of Scott Joplin -related ragtime piano idioms will also be covered. I’ll conclude by emphasizing how music is an excellent medium that displays the intimate relationship between science and art, and is a great vehicle to teach science.
