OK so we’ve all made yoghurt pot shakers and rubber band guitars but what lies beyond that? There is little to match the joy of making music on instruments that you have created yourself. This site is not about fine craftsmanship, although attention to detail and aesthetics do matter, but more about creating stuff that creates sound, learning the principles so you can explore for yourself.


This website is aimed at inquisitive musical instrument builders at all levels, many will be the same people who write the articles of their experiences and lessons learned, others want stuff to pass a wet saturday afternoon with the kids.

parts1There is an entire world of musically-usable sounds that are readily accessible. Some instruments are more complicated than others, some require tools and special materials in construction, others simply require imagination and experimentation with household objects – the secret is to enjoy the process and the outcome, learn from your experiences and share with others. If you’ve made something that’s not here, tell us how you made it, send us photographs, audio or video files, a few lines to explain or more would be great.

The site has some theory that is necessary to make an effective instrument, a lot of the content is based on specific instrument projects, each will have core elements that, with a little imagination and understanding, can be applied more widely. Each project will have a skill rating (hard to difficult) and tooling level (none, household, workshop, specialist) indicated. Instruments are categorised using the Sachs Hornbostel system which uses the instrument’s sound-generating element to define the instrument.

THE first book in your builder’s library should be Bart Hopkin’s – Musical Instrument Design. Here Is A Link – It has more inspiration in its pages than you’ll ever need. We builders and inventors owe him big time – Thanks Bart.
