Composing Today

23 September 2008
A little history: about a year ago I received an email out of the blue from the Duo Ahlert and Schwab asking if I would write a piece for their mandolin guitar duo. It seems these folk are the foremost mandolin-guitar duo in Europe and like modern music and especially American composers. I wrote back and said I’d write something small by Christmas of this year. I’ve finally come to embrace the idea of writing this piece – on the one hand I have no performances scheduled and any performance is a good one especially if it gets me to write a new piece. I began to think about the instruments and realized that I could actually get some serious harmonies out of these two fretted instruments especially if I retuned the strings. So I began exploring the retuning possibilities of the instruments.
If we begin with the guitar, one problem I encountered was no matter how I tweaked the tuning I still ended up with that awful fourth-laden sonority that defines the guitar. I realize now that the problem was result of the fact that I was approaching the tuning from the wrong direction – I was trying to get the most quarter-tones I could get out of the combination of the instrument rather than rethinking the instrument completely. So today, I began trying to rethink the pitch continuum of the guitar. Guitars are normally tuned E-A-D-G-B-E which is a two octave span; 24 semitones or 48 quarter tones. I thought that what I should do to the guitar is divided this space up evenly. Thus the five intervals between pitches would be divided into the 48 quarter tones which obviously is uneven. So if I expand the space to 50 – I could tune in equal 10 quarter tones orfive semi-tones or P4 which sounds like the guitar. Instead I shrunk the space and tuned it in equal 9/4 tones: E – Aqb – C# - Fq – A# - Dq – this actually changes the sound of the instrument.
For the mandolin we usually tune in fifths like the violin: G-D-A-E. Instead I thought to again retune the space. My choices were equal 15/4 or 13/4 intervals. 13/4 intervals tend to sound a hell of a lot like tritones, but 15/4 intervals have their own special sound and that’s what I’ve currently chosen: Gqb – D – Aq – F. The other thought that comes to me now is to tune the mandolin like the guitar – thus with a smaller interval between strings 2 and 3, something like: G-Eb-Ab-E or something with quarter-tones, perhaps I’ll experiment with that as well.
I was talking with Carla about the poetic concept for the piece and the image that kept coming back to me was of a blind man we saw in Urumqi. He was being led around by his wife and was playing the erhu, she held a bucket to collect coins; most people gave. What is striking about this image in the context of the retuning of the guitar is that for this man, and for the blind, he could have been walking this path for fifty years playing his erhu. His path remained the same, but the environment around him changed – thus for the guitar and mandolin players we have a similar thing – they are strumming their strings but the instrument is different – the environment of sound is different though the fingerings and strummings are the same.
I realize also in retuning these instruments that we have then three separate pitch worlds possible: the tempered world; the quarter-tone world and the fusion of the two. Perhaps I can work something out whereby the environment moves from one to another. We’ll see.
Today I composed out some rhythmic sections that may make it into the final work – likely toward the end. We’ll see about that as well.
