What counts as mechanical music and mechanical musical instruments?
Updated
Mechanical music is music produced by a self-playing or automatic instrument rather than by a person's fingers. The Musical Box Society of Great Britain (MBSGB) defines the category by how the notes are set: a mechanical programme—pins on a wooden barrel or metal cylinder, or punches in a disc or in strips of metal, card or paper—determines what the instrument plays.
The defining test
An instrument counts as mechanical music when the sequence of notes comes from a physical programme, not from live performance decisions. The performer may start, stop or change the programme, but the notes themselves are fixed by the medium. That is why the MBSGB describes the field as "self-playing, or automatic, musical instruments."
Common examples
The MBSGB lists several instrument families under this heading:
- Musical boxes — the society's namesake instrument, with notes pinned on a barrel or cylinder.
- Organettes — small mechanical reed or pipe organs driven by a punched programme.
- Automatic pianos and organs — versions of conventional instruments that play themselves from a mechanical record.
The society treats these as examples rather than a closed list; the shared feature is the mechanical programme, not the instrument's shape or size.
Programme formats to recognise
| Programme medium | Typical use |
|---|---|
| Pins on a wooden barrel | Barrel-operated musical boxes and similar instruments |
| Pins on a metal cylinder | Cylinder musical boxes |
| Punched discs | Disc-operated instruments |
| Punched metal, card or paper strips | Organettes and other strip-read instruments |
If you can point to one of these media as the source of the notes, you are looking at mechanical music in the MBSGB's sense.
Why the distinction matters
The definition shapes what the society collects, researches and publishes on: the history and maintenance of these instruments, plus advice on collecting, valuations and restoration for members. It also explains the society's international membership, which spans Europe, North America, Asia and Australasia—mechanical instruments were made and traded across all those regions.
Where to go next
The MBSGB website has a "New to musical boxes or mechanical instruments?" section for beginners, alongside resources including a musical box register, tune sheets and tune lists, repair information and a reading list.
