Electric harp

The first such commercially manufactured instrument was made by Camac, also helped later by the request of jazz-pop harpist Deborah Henson-Conant.

[1] The result looked like a light framed Celtic-style harp, but each string had a crystal (Piezo) pickup at its base.

In the late 20th century instrument builder and American musician Robert Grawi created an electric double harp-lute based on the West African kora but strung and tuned differently.

The gravikord is a light ergonomically designed instrument made of modern materials mostly stainless steel tubing.

It is a double harp that has 24 strings evenly divided in two ranks arrayed on a free standing "Vee" shaped bridge made of synthetic material including an integral piezo-electric sensor.
