Western

Guitar, Plucked stringed instrument. It normally has six strings, a fretted fingerboard, and a soundbox with a pronounced waist. It probably originated in Spain in the early 16th century. By 1800 it was being strung with six single strings; 19th-century innovations gave it its modern form. In the 1940s Les Paul invented the solid-body guitar; lacking a soundbox, it transmits only the string vibrations. With its long-sustained notes, affinity for strong amplification, and capacity for producing wailing melodic lines and harshly percussive rhythms, it soon became the principal instrument of Western popular music.

A musical keyboard is a set of adjacent depressible levers or keys on a musical instrument. Keyboards typically contain keys for playing the twelve notes of the Western musical scale, with a combination of larger, longer keys and smaller, shorter keys that repeat at the interval of an octave. Pressing a key on the keyboard makes the instrument produce sounds—either by mechanically striking a string or tine (acoustic and electric piano, clavichord), plucking a string (harpsichord), causing air to flow through a pipe organ, striking a bell (carillon), or activating an electronic circuit (synthesizer, digital piano, electronic keyboard). Since the most commonly encountered keyboard instrument is the piano, the keyboard layout is often referred to as the piano keyboard or simply piano keys.

The drum is a member of the percussion group of musical instruments. Drums consist of at least one membrane, called a drumhead or drum skin, that is stretched over a shell and struck directly with the player's hands or with a percussion mallet to produce sound. Drums are the world's oldest and most ubiquitous musical instruments, and the basic design has remained virtually unchanged for thousands of years.

Drums acquired even divine status in places such as Burundi, where the karyenda was a symbol of the power of the king.
