Perpetual Happiness

Perpetual Happiness is a reworking of the opening duet from Stephen Sondheim’s Passion, sung by two lovers who will not end up staying together. I am fascinated at how Sondheim has written a perfectly realized romantic duet while simultaneously undercutting the permanence of that love, embodying both the devotion and the falsity in the relationship. I used nothing but the notes of the original piano-vocal, arrayed as a virtuoso moto perpetuo for Tony as a way of exploring and illuminating how the musical materials of the original create their subtle commentary on the illusions of superficial romantic love.

Perpetual Happiness is part of pianist Anthony de Mare’s project Liaisons: Re-Imagining Sondheim from the Piano.

The score is available here. Tony’s ECM recording is available here.

Perpetual Happiness is also part of my ongoing project A Book of Days. You can visit 2 October to hear my original demo of the piece.

I wrote an essay about the piece that’s available at the bottom of this page.



13one was written for the trombonist Will Lang. He asked for a thirteen-note piece that could be played solo or in conjunction with other thirteen-note pieces. I decided to make my piece an homage to John Cage on his 100th birthday.

You are welcome to play the version I cast for Will for the premiere, which is in the downloadable score you will find below. Each of the thirteen notes should be played for the duration of one breath at a generally quiet dynamic. The thirteen notes do not need to be played evenly: let your breath determine the duration of each note. Also, if a particular hexagram speaks to your condition, feel free to milk it.


Cast the I Ching using whatever method you prefer. (There is of course an app for this.) Use the chart you will find in the score to translate each resulting hexagram into a note. If the hexagram you cast has changing lines, the next note should be the one associated with the hexagram that results when you change the lines. If your cast for the thirteenth note gives you a hexagram with changing lines, you can

  1. sing the note of the original hexagram while playing the note of the changed version (or vice versa)
  2. vividly imagine the changed version’s note after you finish playing the thirteen written notes
  3. sing the note to yourself at some later time
  4. use it as the first note of your next performance of the piece
  5. invent your own use for the extra note

If you wish, you can play the piece into a very long delay a la Brian Eno. Set the delay to be longer than the duration of any individual note you are likely to play. Depending on the regen you set, the delay can end up keeping all thirteen notes in play, with a fadeout to nothingness as the delays gradually dissipate. A standard delay pedal is not likely to be long enough for this purpose: you will probably need a computer. I have made a Max for Live patch that implements a long delay (up to 13 seconds), which I am happy to send you when you order the performance materials.

Pump Music

Pump Music is inspired by a series of hand pumps I encountered in campsites while traveling down the Mississippi River in 2009. I recorded this pump at a campsite called Wanagan’s Landing, which was the place we stayed after the very first day of paddling, on 1 August 2009. It’s maybe ten miles down from the headwaters of the Mississippi River, in northern Minnesota.

I was struck not only by the raucous noise of the pump, but also by the unearthly melody of the afterglow as the water recedes back into the earth when you stop pumping. The melody is not a simple overtone series as you might expect, but some curious phenomenon emerging from the length and diameter of the pipe that I don’t have enough physics to understand.

Pump Music was commissioned for the Guidonian Hand and Mary Rowell by Meet the Composer/Commissioning Music USA, and is dedicated to them with vast affection.

Pump Music is part of my ongoing project, A Book of Days. To hear the premiere performance (at Roulette on 1 June 2012), please visit August 1st.
