“My son would like to learn the Harpsichord”
Here is a Harpsichord. It’s a keyboard instrument from the Renaissance and Baroque period of the 1700-1800’s. It was very fashionable in its day. As were powdered wigs and knee britches.
While there is a Harpsichord Society in the UK, we find that parents are normally confusing a Harpsichord with the short name for the harmonica – the harp or mouth harp. Here is a picture of our harp. It’s a member of the reed instrument family.
It wasn’t around when the Harpsichord was popular, but you could try wearing a wig and knee britches when you play it. Why not investigate inside the harmonica, how a harmonica is made, different types of harmonica, or the harmonica’s closest relatives?
