Lesson 4 - Music Box

Introduction

In this lesson, we will create a music box robot. But first - what is a music box? Have you ever seen one?

The music box originated in Switzerland in the late 18th century, when watchmakers adapted clockwork mechanisms to pluck tuned metal combs. Early models were luxury items, often built into snuffboxes, watches, and elaborate furniture. By the 19th century, mass production made music boxes more affordable, spreading their popularity across Europe and America. Though largely replaced by phonographs and modern devices, they remain cherished collectibles and symbols of craftsmanship and nostalgia.
