And War Itself Shall End

July 12th, 2014


And War Itself is an early attempt at musique concrète
This was recorded/performed in 1983 and I used reel-to-reel, cassette tape, LP records and a HP-85 with 16k of ram, custom HP 8bit CPU @ 0.613MHz, running a BASIC program I made, recorded at the lab at work.

Probably most notable for being so old and crude.
And perhaps the nuclear explosion towards the end.

Hewlett-Packard who unwittingly placed a reasonable sound interface on a scientific personal computer that was -supposed- to be acquiring data from a gas chromatograph.

Various effects records and a JFK speech manipulate via tape and a cheap Radio Shack 4 mono channel mixer

acoustic aeolian aluminum downspout harp

This is a popular design on the internet and also the beginnings of making a acoustic audio art installation at my home. The audio linked below is not of very good quality. It has a lot of environmental noise and the harp itself is a bit “screechy” when the wind finally catches it good. I have a lot of experimenting to do to optimize this design because unlike the electric harp where you can just “turn it up” this relies on making a nicely resonant system. The length is about 4 feet and the string length is about 3.5 feet and the nylon fishing line is 50 pound – the heaviest I could find. I actually stuffed the zoom H2 -inside- the harp to get the recording. As with any aeolian harp the harmonic series, not the fundamental of the string, plays the central role in the pitch you hear.

Stars and Stripes Forever in Gene Ward Smith’s Hemifamity27

July 6th, 2014


Stars and Stripes Forever transtuned to 12 of 27 from hemifamity27 – marching band sans percussion.
The master tuning is here.

The midi file that I found is of medium quality and this is decidedly a demonstration piece – this tune was chosen because it is a favorite of Gene’s. To get around having to transpose each note individually or as a pitchclass I use the method of picking 12 notes out of the 27 note set and used that to retuned Garritan Concert and Marching Band samples. The actual tuning is listed below. I think it notable that the rather large deviations from 12 equal, where each step is exactly 100 cents, is not very evident if at all.
