What 'rare' actually means
The word 'rare' is loose in the instrument world. For this desk it means an instrument whose supply is genuinely constrained — not by marketing, but by geography, age, or the number of people alive who can build it well. Three cases: a concert grand from a top atelier with a long waitlist; a violin from a maker who died before 1900; and a bow whose stick was cut from wood you can no longer legally source.
Everything else is a good instrument. That is a different, useful category — but it is not rare.
The three practical categories
- Concert & parlour grands. The instruments that anchor a room. See our Grand Pianos pillar and the Steinway vs. Bösendorfer guide.
- Antique violins, violas and cellos. Overwhelmingly European, mostly Italian and French. Covered in Violins & Cellos.
- Bows. Often the most considered purchase a serious string player makes; the bow is not an accessory.
How the desk approaches provenance
An instrument without paperwork is a story. An instrument with paperwork is an asset. The difference is documentation you can independently verify: a written certificate from a recognised expert (for strings, a house such as Beare, Machold or Bein & Fushi historically; for pianos, a factory dossier), restoration records, and a chain of prior ownership that does not disappear for decades.
Where we help arrange an introduction, provenance is disclosed in writing before any conversation about price.
Where instruments actually live
The best instruments rarely sit in shops. They sit with players, in foundations, in museums, and — quietly — with the two or three dealers per country who are trusted enough to handle them off-market. Auction houses are useful for price discovery, less useful for the best examples.
