The top number in a time signature is easy to understand. Is the song in four? Count “one, two, three, four.” Is it in three? Count “one, two, three.” Is it in five? Count “one, two, three, four, five.” That’s all there is to it. However, the bottom number is another story. What is going on down there? I collected various examples of time signatures in this track I made, but I didn’t understand why “Solsbury Hill” by Peter Gabriel is in 7/4 but “One More Night” by Can is in 7/8. I’m not alone in finding this confusing. My students struggle with it too. They are right to! Every explanation I h ..read more

In class we have been talking about secondary dominants, where you temporarily treat a chord as a new key center before returning to the main key. In a modulation, you move to a new key center and stay there (for a while, anyway). Modulations were a common songwriting technique in pre-rock popular music, and a somewhat less common one in the rock era. They have become increasingly rare in the Anglo-American pop mainstream, though they are still a feature of game and film scores. Let’s start in the jazz era. Many if not most of the midcentury standards modulate to a new key at least once. The ..read more

This week in aural skills, we’re working on various harmonic tropes based on IV-I root movements. This chord progression is technically called the plagal cadence, but is more memorably nicknamed the “Amen” cadence because it’s a traditional European hymn ending. (It has nothing to do with the Amen break, though they do sound good together.) The plagal cadence is the mirror image of the classical V-I authentic cadence. Where does the word “plagal” come from? The Online Etymology Dictionary says that it’s probably from Greek plagios, meaning “oblique” or “side”, and that word in turn comes from ..read more

My NYU aural skills students are working on chord identification. My last post talked about seventh chords; this post is about chords with more notes in them, or at least, different notes. My theory colleagues call them added-note chords. They are more commonly called jazz chords, though many of the examples I list below are not from jazz. You could also call them extended chords, or complicated chords, or fancy chords, or cool chords. It’s easy to get overwhelmed by all the numbers and symbols. My preferred way to organize all this information is to think of chords as vertically stacked scale ..read more

After spending their first few years writing abstract psychedelic tunes, the Grateful Dead took a hard turn into Americana. They wrote a bunch of songs inspired by blues, country and folk, and in doing so, they massively expanded their listener base. Several of these songs involve outlaws and drifters in the Wild West. I think the best of the Dead’s cowboy songs, both lyrically and musically, is “Jack Straw”. When I was a kid, my older stepbrother had a bunch of Dead albums stored in our apartment. I avoided listening to them at first because their covers suggested that would be too heavy and ..read more

As I continue to build groove pedagogy resources, I want to clear up some persistent confusion about polymeter and polyrhythm. If you don’t feel like reading the whole post, it can be summed up in this image: The most concisely I can put this into words: in polymeter, the grid lines are aligned, but the downbeats aren’t. In polyrhythm, the downbeats are aligned, but the grid lines aren’t. Imagine a metronome ticking along. You can group the ticks together to make a meter. Most Anglo-American popular music groups the ticks into units of four or eight or sixteen; this is called duple or quadrup ..read more

St Stephen might be the most “Grateful Dead” of Grateful Dead songs, the one that (for better or worse) sounds the most like them and the most unlike anyone else. It’s a cliche with the Dead to say that the live version is better than the studio version, but in the case of “St Stephen”, it’s true. The version on Aoxomoxoa is too fast and has some awkward arrangement choices. The canonical recording is the one from Live/Dead. This is a mess, but it’s a lovable mess. A few things I particularly enjoy: the feedback from (I think) the bass at 0:21; Jerry’s off-mic yell of satisfaction at 3:37; th ..read more

If you flatten the seventh note of the major scale, you get Mixolydian mode. It’s like a spicier version of major. Mixolydian is a medieval mode that fell out of favor with “art” music composers during the Baroque era. However, it stayed alive and well in various European folk traditions before having an explosion in popularity during the rock era, helped by its resemblance to the blues. Here’s an interactive walkthrough via the magic of Noteflight. Music in Mixolydian “India” by John Coltrane is in G Mixolydian. Coltrane was deliberately trying to invoke Hindustani classical music, as the t ..read more

The Grateful Dead always had a folkie/Americana aspect, but in the early 1970s they leaned hard into country music, and it suited them. I found this song to be pretty cringe as a teenaged Deadhead in New York City, but it grew on me. The tune is named for a 1940s radio Western, which sounds like it could have been the basis for Woody’s Roundup in Toy Story 2. For all I know, Robert Hunter had never been within a thousand miles of Tennessee when he wrote the lyrics, but they work okay if you don’t think about them too hard. If you want to learn to play the tune, this is a good tutorial video ..read more

Dust-to-digital posted this lovely performance of “Washington Blues” by Elizabeth Cotten. It reminded me that she is the greatest and that I should write more about her. If you are a guitarist, you might notice that there is something strange about her technique. She was left-handed, but rather than stringing a guitar in reverse the way lefties usually do, she just played a standard-strung guitar upside down. She had to learn her own idiosyncratic chord shapes, and she played them by alternating bass with her fingers and playing melody notes with her thumb. This must have required some dedica ..read more
