The hammered dulcimer is a percussion-stringed instrument which consists of strings typically stretched over a trapezoidal resonant sound board. The hammered dulcimer is set before the musician, who in more traditional styles may sit cross-legged on the floor, or in a more modern style may stand or sit at a wooden support with legs. The player holds a small spoon-shaped mallet hammer in each hand to strike the strings. The Graeco-Roman word dulcimer derives from the Latin dulcis (sweet) and the Greek melos (song). The dulcimer, in which the strings are beaten with small hammers, originated from the psaltery, in which the strings are plucked.

A musical instrument is a device created or adapted to make musical sounds. In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument. A person who plays a musical instrument is known as an instrumentalist. The history of musical instruments dates to the beginnings of human culture. Early musical instruments may have been used for rituals, such as a horn to signal success on the hunt, or a drum in a religious ceremony. Cultures eventually developed composition and performance of melodies for entertainment. Musical instruments evolved in step with changing applications and technologies.
