Hurdy-gurdyThe hurdy-gurdy is a string instrument that produces sound by a hand-crank-turned, rosined wheel rubbing against the strings. The wheel functions much like a violin bow, and single notes played on the instrument sound similar to those of a violin. Melodies are played on a keyboard that presses tangents—small wedges, typically made of wood or metal—against one or more of the strings to change their pitch. Like most other acoustic stringed instruments, it has a sound board and hollow cavity to make the vibration of the strings audible.
LyreThe lyre ('laɪər) is a stringed musical instrument that is classified by Hornbostel–Sachs as a member of the lute-family of instruments. In organology, a lyre is considered a yoke lute, since it is a lute in which the strings are attached to a yoke that lies in the same plane as the sound table, and consists of two arms and a crossbar. The lyre has its origins in ancient history. Lyres were used in several ancient cultures surrounding the Mediterranean Sea. The earliest known examples of the lyre have been recovered at archeological sites that date to c.
ErhuThe erhu (; aɻ˥˩xu˧˥) is a Chinese two-stringed bowed musical instrument, more specifically a spike fiddle, which may also be called a Southern Fiddle, and is sometimes known in the Western world as the Chinese violin or a Chinese two-stringed fiddle. It is used as a solo instrument as well as in small ensembles and large orchestras. It is the most popular of the huqin family of traditional bowed string instruments used by various ethnic groups of China.
Double bassThe double bass (ˈdʌbəl_beɪs), also known simply as the bass (beɪs), amongst other names, is the largest and, therefore, lowest-pitched chordophone in the modern symphony orchestra (excluding unorthodox additions such as the octobass). Similar in structure to the cello, it has four, although occasionally five, strings. The bass is a standard member of the orchestra's string section, along with violins, viola, and cello, as well as the concert band, and is featured in concertos, solo, and chamber music in Western classical music.
HarmonicA harmonic is a sinusoidal wave with a frequency that is a positive integer multiple of the fundamental frequency of a periodic signal. The fundamental frequency is also called the 1st harmonic, the other harmonics are known as higher harmonics. As all harmonics are periodic at the fundamental frequency, the sum of harmonics is also periodic at that frequency. The set of harmonics forms a harmonic series. The term is employed in various disciplines, including music, physics, acoustics, electronic power transmission, radio technology, and other fields.
HarpThe harp is a stringed musical instrument that has individual strings running at an angle to its soundboard; the strings are plucked with the fingers. Harps can be made and played in various ways, standing or sitting, and in orchestras or concerts. Its most common form is triangular in shape and made of wood. Some have multiple rows of strings and pedal attachments. Ancient depictions of harps were recorded in Mesopotamia, Persia (now Iraq and Iran) and Egypt, and later in India and China.
