No. 7: A 47 Button Hayden Duet and Leather Case

Introduction

My latest instrument is a very special custom 47 button Hayden duet. I also made a bespoke hard case to store and transport it.

Here is a demonstration of it being played by its owner, Israel Sánchez. The set has two tunes. The first is a waltz/bourree composed by José Climent. The second is a traditional pasacalles from the Aliste region of Spain.
