Definition: Ratchment is a type of musical instrument that originated in India and was popularized during the 19th century. It consists of two metal rods (known as rakesh) connected by a wooden rod called an "rath". The raths are used to create percussive sounds, which can be described as a combination of woodwinds and brass instruments. Ratchments were often played in orchestras and jazz bands during the early 20th century.
