Today we are going to write a harmony using mostly seventh chords and we will look at a strategy to deal with non-chord notes when we are writing music. This combines a couple of our past lessons so be sure you watched those videos...

Identifying music intervals can be one of the more confusing things about learning music theory for the first time. In this video we will look at an easier way to find the names of intervals using the major scale as a reference point....

Sometimes you need to have two different music parts to be playing at the same time in the same staff. Or, you might want to save space by having two voices share a staff. One of the best ways to achieve this is to use the voices feature...

In this lesson we will go over three more complex versions of the seventh chord - minor, augmented, and diminished. We will go over the different scale degrees used in the chords and how to build them. We will look at examples of each...

Princeton University physicist Paul Steinhardt reveals how irrational ratios of two repeating patterns produces intriguing and unexpected effects.

Princeton cosmologist Paul Steinhardt recalls his initial enchantment with cosmic inflation when he first heard Alan Guth suggest it in a talk in 1982.

2003 Nobel Laureate Antony Leggett, University of Illinois, describes his belief that reductionistic approaches to physics are not always the right way to proceed, describing how the possible breakdown of the laws of quantum mechanics...

Cosmologist Paul Steinhardt (Princeton) describes the so-called "initial conditions problem" that makes cosmic inflation very hard to start.

Imperial College cosmologist Claudia de Rham describes her view of how reinterpreting Einstein's theory of gravity in terms of particle physics gives a more coherent and elegant picture of the forces of nature.

Physicist Paul Steinhardt, Princeton University, describes how his interest in inflationary cosmology was piqued by a captivating talk given by Alan Guth 30 years ago, and how what he thought was going to be a few weeks' diversion has...

Cosmologist Rocky Kolb (Chicago) provides a brief background on the mystery of dark energy while explaining why the phenomenon is personally bothering him.

Former Harvard and Stanford psychologist Stephen Kosslyn describes his excitement at becoming Founding Dean of Minerva Schools.

We explore the Pentatonic scale. As the title suggests the scale comprises 5 notes instead of the 7 notes that make up the major scale and the minor scale. This music theory lesson looks at the different ways of calculating the notes...

This music performance lesson explores the essentials required in the delivery of scales and arpeggios then explains the finer points that can be applied in scales and arpeggios in order to generate superb technical control and musical...
