I have been reading the tuning list now for about a year with great interest. I have enjoyed reading all the helpful advice from microtonalists around the world. My interest in microtonality came from work in 1976-86 with Jon Glasier in San Diego, when I lived there and studied at UCSD. Jon introduced me to Ivor Darreg, Irv Wilson, John Chalmers and others. In the late 1970's I built many microtonal instruments of my own invention, including a 31 tone kalimba (the Finger Piano), several plucked and bowed zithers, a 300 foot long guitar, some tubalongs (after Erv Wilson's designs), spring instruments, and many balloon instruments (see below). Lately I have been using Csound to explore 53 tone equal temperment. The balloon instruments include: - Balloon Flutes made from sewer pipes and balloon membranes These exploit the characteristic of pipes with variable flexible ends to vary pitch by the elasticity of the membrane. - Aeromembranophones - Peanut butter jar lid with a balloon membrane stretched over it creates a membrane; blow hard and watch out - Balloon Bass - long sewer pipes with balloon reeds - Balloon Shrieks - Balloon as a resonator and suspension device for percussion instruments, including plow shares and stainless steel wing sculptures I still listen to some of the microtonal music I recorded of Jon Glasier, myself and friends in San Diego, and Tom Nunn and others in San Francisco in the mid 1980's. I have about 150 hours of casette tapes that contain many jewels of detwelvulated exploration. Some of the articles in the recent TUNING list messages were especially interesting. Brian McLaren's post in Digest 910 Nov 29, 1996 mentions problems notating the "huge triangle of space alloy that sits atop a balloon". I remember when we first used balloons for this purpose, not as resonators, but rather to keep the "wings" vibrating longer. The resonating quality of balloons was a side effect, along with the bounciness that made the timbre change. Brian's post from Nov 25, 1996, asks for sophisticated software for microtonality. I have not used MIDI lately, but I have written a small program that generates microtonal Csound SCORE files, which can generate 53 tone music with efficiency. It's kind of a macro processor, written in TURBO Pascal for DOS. Not state of the art, but effective for working in equal temperments like 53 tone. The composer dictates the note numbers (1-53) and their duration, and a few other items, and the system writes out the Csound score file. Csound is then called to create a .WAV file, which can be listened to. I must say that most of Brian's rantings get sent very quickly to the bit bucket. His railings against academia are childish. If you don't like something, then fix it. Go teach in a university, and stop complaining. November 22, 1996, Digest 904 has Daniel Wolf asking for a description of making your own pickups. I made many of these for kalimbas, zithers, and spring instruments. The basic idea is a magnet, with coils of magnet wire around it. The wire is very fine, perhaps the width of a hair, insulated with a thin plastic coating. I used an old 33 rpm record turntable to wind the pickups. At first I was very picky about the magnets, but I eventually found excellent results with ceramic magnets, which were about six inches long, by 1/4 inch wide and very cheap. Smaller magnets can be used for smaller pickups. I would wind magnet wire until it was about 1/4" thick, perhaps 1,000 coils or so. Then plug one end of the wire into the positive terminal of a mini plug, and the other end into the negative end, then send the result to a mixer or amplifier. wire wire wire wire wire wire wire wire wire wire to mini-plug ---> i +-------------------------------------------+ w r + magnet + i e +-------------------------------------------+ r wire wire wire wire wire wire wire wire wire wire to mini-plug ---> At present I sell mainframe computers for IBM in Boise, Idaho; ski, fish, and white water raft through the wilds of the western slope of the rocky mountains; and indulge in midnight Csound explorations.
