What are the greatest basslines ever?

The bassline is neglected by most non-musicians. But if you want to write or produce music, you quickly find out how important it is. The bassline is the foundation of the whole musical structure, both rhythmically and harmonically. The best basslines interlock with the drums and other rhythm instruments to propel the groove, without you necessarily even noticing them. I like the complex walking lines in jazz and melodic lines in highbrow rock, but the ones that really hit me where I live are basic riffs that loop and loop until they lift you into an ecstatic trance.

Here are my favorite basslines of the last fifty years, across genres.

John Coltrane – “My Favorite Things”

Simple, hypnotic, effective. Read more.

John Coltrane – “Equinox”

Another devastatingly simple groove.

How do I learn to improvise music?

Improvising music is like giving a speech off the cuff. Before you can do it, you need to know some vocabulary and grammar. In music, the vocabulary is riffs, phrases, scales, sequences and other melodic building blocks. The grammar is music theory. It’s not necessary to learn either one formally, you can figure them out on your own through trial and error. But a good teacher can make the process a lot easier.

What is the evolutionary purpose of dreaming?

Dreaming doesn’t have an evolutionary purpose per se. It’s just an emergent property of the piecemeal way our brains have evolved, from the older and more automatic systems out to the newer, learning-enabled systems. I’ve seen it suggested by several different scientists that most animals go about their waking lives in a state similar to the one we experience in dreams: centered in the present, with little notion of past or future, just strong sensations and automatic reactions to those sensations. The theory, then, is that our lizard brains take over in dreams, but instead of experiencing the real world, they explore the memories accumulated in the neocortex.

Visualizing music

Computer-based music production and composition involves the eyes as much as the ears. The representations in audio editors like Pro Tools and Ableton Live are purely informational, waveforms and grids and linear graphs. Some visualization systems are purely decorative, like the psychedelic semi-random graphics produced by iTunes. Some systems lie in between. I see rich potential in these graphical systems for better understanding of how music works, and for new compositional methods. Here’s a sampling of the most interesting music visualization systems I’ve come across.

Music notation

Western music notation is a venerable method of visualizing music. It’s a very neat and compact system, unambiguous and digital, and not too difficult to learn. Programs like Sibelius can effortlessly translate notation to and from MIDI data, too.

"Chameleon" by Herbie Hancock

But Western notation has some limitations, especially for contemporary music. It doesn’t handle microtones well. It has limited ability to convey performative nuance — after a hundred years of jazz, there’s no good way to notate swing other than to just write the word “swing” at the top of the score. The key signature system works fine for major keys, but is less helpful for minor keys and modal music and is pretty much worthless for the blues.

Here’s a suggestion for how notation could improve in the future. It’s a visualization by Jon Snydal of John Coltrane’s solo in Miles Davis’ “All Blues”  (I edited it a little to be easier on the eyes.)

Snydal’s visualization is more analog than digital — it shows the exact nuances of Coltrane’s performance, with subtle shadings of pitch, timing and dynamics.

Who are the best mashup DJs?

DJ BC is my favorite mashup artist right now. He deserves the nod just for Snoop’s Nu Shooz:

Why has the human brain evolved so much more than any other animals?

The human brain isn’t “more” evolved. It’s just differently evolved. Our intelligence has its obvious advantages, but it carries some significant costs. Like Joshua Engel says, the big brain is metabolically expensive. It makes childbirth much harder for humans than for other mammals, too. Human babies have to be effectively born prematurely in order to fit the big head through the birth canal, and even so, it takes years for the brain to develop to the point where a person can function on the most basic level. Other mammals are up and walking in a matter of hours, and are ready to fend for themselves after a few weeks.

How do you isolate samples like Girl Talk?

Girl Talk doesn’t actually isolate sounds; it’s almost impossible to do that. You can use EQ to quiet background sounds to a limited extent, but there’s no way to perfectly isolate sounds from a mixed track. Girl Talk and other mashup artists rely heavily on a capellas (vocal-only mixes) and instrumentals, which are included with DJ versions of most pop, hip-hop and dance tracks. A few isolated stems have also been leaked from the Rock Band and Guitar Hero games, they pop up online here and there. Every so often an artist will release tracks separated into stems officially. Kanye West even gives away stems of “Love Lockdown” for free on his blog.

Biggie Biggie Smalls Is The Illest

I always enjoy when hip-hop artists sample themselves. It makes the music recursive, and for me, “recursive” is synonymous with “good.” You can hear self-sampling in “Nas Is Like” by Nas, “The Score” by the Fugees and many songs by Eric B and Rakim. The most recent self-sampling track to cross my radar is “Unbelievable” by Biggie Smalls, from his album Ready To Die. Here’s the instrumental.

Why do people like Girl Talk?

I don’t enjoy Girl Talk’s music all that much — I find it overwhelming, like watching someone flip channels on a TV. But I think he’s really important, and anyone who cares about music, technology, originality and ownership should be paying close attention. Adam Bossy raised an intriguing idea in his answer — describing an unlikely pairing of Black Sabbath and Ludacris, he observes: “It sounds as though each song was originally written with the other in mind.” At his best, Girl Talk finds connections between seemingly distant genres and styles, and shows that maybe the commonalities run deeper than the differences. This is a big idea, and an exciting one.

Does teaching Intelligent Design in schools really damage science?

You don’t go to high school biology class to learn particular facts; you go to understand the general framework of evolutionary theory. Rather than contradicting any single fact, Intelligent Design undermines the entire intellectual basis of biology.
