No. 10: A 45 Button Crane Duet

Crane, Duet /

The tenth instrument I built was another Crane duet. It was for John Thornton of Hampshire, the same client who commissioned No. 4. I am fortunate to have several customers who, after receiving their first Holden concertina, immediately placed an order for a second one. No. 10 is very similar in many ways to No. 4, with one obvious difference (metal instead of wooden ends) and a lot of small differences that I will list later. You might find it interesting to read my article about No. 4 as background to this article.

In this video, John performs five tunes on No. 10 and talks a little about his modifications to the standard Crane duet layout.
