The whole tone scale

Like diminished chords, the whole tone scale is not very widely used, but when you need that specific vibe, nothing else will do. Whole tone scales are easy to understand, because there are only two of them total. Whichever key you are in, there is a whole tone scale that includes the tonic, and another one that doesn’t. I have never seen a useful naming system for these two scales, so I call them yin and yang.

Notice that the notes not found in yin are all the notes in yang, and vice versa. Another fun thing is that when you write the whole tone scales on the circle of fifths, they look exactly the same as they do on the chromatic circle – all the yang scale tones just switch places with their counterparts a tritone away. Symmetry! Continue reading

The mystical tritone

I’ve picked up some new guitar students lately, so I’m once again doing a lot of explaining what a tritone is and why people should care. Whenever I find myself explaining something a lot, I like to encapsulate it as a blog post. So here we go.

A tritone is the interval between the notes C and F-sharp. It’s also known as the flat fifth or sharp fourth. It’s two minor thirds, three whole steps, six half steps, or half an octave. On the piano, count six keys up or down. On guitar, count six frets.

The tritone is the heart of the entire western tonal system. The clearest way to define the key center of a piece of music is to look at how tritones create tension and resolve it. Tritones are also central to the sound of the blues and blues tonality, which form the basis of most of the music I like.

Capturing sound

I was doing a frivolous Google search for the Simpsons episode where Bart, Nelson, Milhouse and Ralph form a boy band. They’re in the studio singing, and they sound terrible, until the producer pushes a huge button labeled “studio magic.” Then suddenly they sound like the Backstreet Boys. While I was digging through the Google results, I came across a book called Capturing Sound: How Technology Has Changed Music by Mark Katz. He references the Simpsons gag as an example of how recording technology has undermined our notions of authenticity in music. There are a couple of chapters of the book online, and it’s great stuff.

It’s hard for us now to imagine a time when recorded sound was a wondrous technological novelty.

Those gathered around the phonograph were experiencing music in ways unimaginable not so many years before. They were hearing performers they could not see and music they could not normally bring into their homes. They could listen to the same pieces over and again without change. And they ultimately decided what they were to hear, and when, where, and with whom.
