Joni's genius is that she creates chords that are ambiguous, chords that have two or more different roots. ...Joni's music is as close to impressionist visual art as anything I've heard. ...harmonic complexity born out of her strict insistence that the music not be anchored in a single harmonic interpretation.

The brain's synapses are programmed to grow for a number of years, making new connections. After that time, there is a shift toward pruning, to get rid of unneeded connections. ...Neuroplasticity is the ability of the brain to reorganize itself. ...the amount of reorganization that can occur in most adults is vastly less than can occur in children and adolescents.

Mozart had extensive training from his father, who was widely considered the greatest living music teacher in all of Europe at the time.

On average, successful people have had many more failures that unsuccessful people.

Collective music making... may have historically served to promote feelings of group togetherness and synchrony, and may have been an exercise for other social acts...

The multiple reinforcing cues of a good song—rhythm, melody, contour—cause music to stick in our heads. That is the reason why many ancient myths, epics, and even the Old Testament were set to music in preparation for being passed down by oral tradition across generations.

The Harvard neuroscientist Gottfried Schlaug has shown that the front portion of the corpus callosum is significantly larger in musicians than in nonmusicians, and particularly for musicians who began their training early. ...Schlaug found that musicians tended to have larger cerebellums than nonmusicians, and an increased concentration of gray matter... responsible for information processing, as opposed to white matter, which is responsible for information transmission.

As a tool for the activation of specific thoughts, music is as good as language. The combination of the two—as best exemplified in the love song—is the best courtship of all.

Memory for playing a musical piece... involves a process very much like that for music listening... through establishing standard schemas and expectation. In addition, musicians use chunking... tying information together into groups, and remembering the group as a whole rather than individual pieces.

The coming together of rhythm and melody bridges our cerebellum and our cerebral cortex.

I think we will see personalized music stations in the next few years... controlled by computer algorithms... I think it will be important that... listeners have an "adventuresomeness" knob that will control the mix of old and new, or the mix of how far out the new music is from what they usually listen to.

Contour refers to the pattern of musical pitch in a melody—the sequence of ups or downs that the melody takes—regardless of the size of the interval.
