What makes a good musical theme? In this episode of Digital Media Insider, we ask Emmy Award-winning composer BJ Leiderman, the melodic mastermind behind NPR's Morning Edition, and PRI's American Public Media's Marketplace. We'll also digitally deconstruct an original theme song to see how it works. (DMI 02-23-2007: 14 minutes 0 seconds)

Production Notes

As usual, I recorded my voiceover with the Rode Podcaster USB mic into BIAS Peak as a 16-bit, 44.1kHz, mono AIFF file. Next, I used Peak's editing tools to delete the false starts and mouth noises.

I recorded the BJ Leiderman interview through a JK Audio QuickTap telephone interface into a Korg PXR4 digital recorder. I then converted the PXR4's MP2 file to an AIFF in iTunes so I could edit it in Peak. There, I snipped out false starts and background noises and adjusted the balance between our voices. I spent quite a bit of time trying to remove the horrendous telephone noise, settling on a combination of BIAS SoundSoap Pro and Izotope Ozone.

Leiderman's music examples started as MP3s; I imported them into Peak, tightened them up with cuts and fades, and then normalized their levels. Because I wrote the Distributing the Future theme, I had access to the original multitrack arrangement (see screenshot), so I rendered AIFFs from the individual tracks.

Distributing the Future Theme

In this closeup of the Distributing the Future theme in Ableton Live, note how the volume envelopes "duck" certain sounds so others can be heard. The melody (bottom track) is played via MIDI on a sine wave sound. The blue dashes represent note duration and pitch. (Click to enlarge.)

Next I imported everything into Ableton Live, where I arranged the music examples around my voiceover and theme music. I compressed and enhanced the voiceover with Ozone. Finally, I rendered the mix to an AIFF file, converted it to an MP3 in Peak, and then used iTunes to clean up the ID3 tags and add artwork.

I produced the Digital Media Insider theme music in Live as well. The opening sound effect is a compressed mouth noise spliced onto a tone cluster I generated in Native Instruments Reaktor. The main groove is from Steinberg Xphraze. (Jim Aikin turned me on to both virtual instruments in his article "My Five Favorite Soft Synths.") The piano is from the Garritan Personal Orchestra, which I discovered when we interviewed Gary Garritan. Then there are a few percussion samples dredged from my hard drive. Altogether, the theme took just six tracks. Effects processing was courtesy of Live's default plugins and Freeverb.
