Simple home-buildable music machines.
An exploration of the sonic world of scrape, and description of a battery of scraped instruments analogous to drum set.
From Routledge Press, a newly released collection of articles from the late great Experimental Musical Instruments journal.
The components in the photo on this page make up a musical instrument called the Speaker Driver Instrument. The elements of it, you can see, are an inexpensive little electronic keyboard, a stereo amplifier, a speaker driver minus its speaker cone, and a scrap of...
Hooray for through-and-through originality: It’s wonderful when a newly conceived musical instrument presents a whole new musical landscape to explore. On the other hand, there’s also value in presenting a new instrument idea with at least some familiar elements –...
In this post you’ll find a description of a potentially very interesting idea in string instrument design. But as you’ll see as you near the end of the post, my attempt to exploit the idea wasn’t terribly successful. Still, it’s an interesting enough concept to...
A melodic friction drum set
A video featuring an ostinato machine and lots of animation.
Two events-per-second instruments: Savart’s Wheel and Musical Siren, with a focus on how to tune for just and equal-tempered scales on instruments of this sort.
Floppy bands of spring steel can be the produce wonderful sounds. This post describes several musical instruments by Bart Hopkin which use such bands.
Sample Libraries from SoundIron featuring instruments made by Bart Hopkin
Four musical instruments using freely suspended stainless steel resonators.
Schmeary Glissary is an 84-tone Equal-Temperament Tubulon
Perfectionism in music-making brings exquisite music into the world. But un-perfectionism brings another sort of richness.
I have been exploring the idea of creating animated videos to accompany music made on my instruments …
Making home-made wind instruments: creating register holes, shaping the “lay” of a single reed mouthpiece, and more.
‘Moes are wind instruments which have a pitch-control system involving an open slit and a magnetic strip. This article discusses recent work developments in the ‘Moe family.
Most instruments produce sound by taking advantage of a natural springiness in things. Far fewer are instruments which create a forced oscillation at specific frequencies.
Does it matter if a new instrument sports a catchy name? Does it matter if it is attractive to the eye?
The making of a very crude beating reed organ.
Most acoustic sound sources produce many frequencies simultaneously, resulting from multiple modes of vibration present in the vibrating body. This article addresses the question of which of these are likely to be most prominent in the tone and to be recognized as the defining pitch.
Getting the impedance relationships right: for many types of musical instruments, this is one of the less appreciated, less understood, and more important aspects of instrument making.
Selected Instruments of the Hopkin Instrumentarium are now to be sampled and released in a series of sample libraries. This is a new filed for Bart, the instrument maker, and in this post he talks about first impressions.
(The Only Article On This Website That’s Not About Musical Instruments.)
An article about magnetic pickups and how best to utilize finite pickup footage space.
Musical strings made from elastic materials bands make an appealing sound. This article discusses the ins and outs of putting them to use, and the various types of elastic material that can serve. It then describes some elastic string instruments that the author has made.
Broad spectrum sounds filtered through tubular air chambers with well defined resonance frequencies: this idea can produce very interesting musical results. This article discusses several instruments that work this way.
Taxonomony is typically one of the first topics addressed in Organology 101. Here’s my take on the subject.
An overview of different ways of creating friction vibrations, a discussion of principles and techniques pertaining to the making of friction instruments, and short descriptions of several friction instruments I’ve made.
Thoughts about the terminology used in talking about the multiple-frequency blends that make up musical and non-musical sounds, and how that terminology relates to the underlying physical reality and the ear’s ways of perceiving such blends.
The second of two articles on making and tuning simple disk gongs. This one describes an approach to tuning that is more sophisticated than the rudimentary approach described in the first article, and addresses the underlying acoustics more than the previous one.
The first of two articles on making simple disk gongs. This one outlines the simpler approach; the other takes on acoustics and tuning questions in a more sophisticated way.
An overview of systems that can be used for controlling pitch in wind instruments, from familiar an conventional to unusual and far-out.
An interactive public sound installation.
Thoughts on the search for quiet in a noisy world.
Depictions of apparatus created in the late 19th century for experimentation and demonstrations in musical acoustics.
Some time ago I posted on this site an essay under the title “Orientation of the Oscillation.” In it I talked about the importance of the direction of the oscillation in an instrument’s main vibrating bodies (strings, bars, tines or whatever): how the orientation of...
With many new instruments it’s both more fun and more musically fruitful not to try to become a virtuoso, but rather to keep an exploratory attitude that lets the instrument take you where it will.
Notes on the Over-Under scales, on a complementary pair of just scales used in a couple of recent instruments.
Notes on the question of patenting for new instruments. (Is it worth it?)
