nice! νομίζω ότι το θέρεμιν πάντοτε θα έχει αυτή την οπτική ιδιαιτερότητα (παίζω στον αέρα), αλλά δεν ήταν το πρώτο ηλεκτρονικό μουσικό όργανο, for sure"In 1897 Thaddeus Cahill patented what was to become the “Telharmonium” or “Dynamophone” which can be considered the first significant electronic musical instrument . The Telharmonium was an immense instrument of about 200 tons in weight and 60 feet in length assuming the proportions and appearance of a power station generator….the quoted cost was $200,000."http://120years.net/the-telharmonium-thaddeus-cahill-usa-1897/
