Percussion instruments is a musical instrument that is sounded by being
struck or scraped by a beater including attached or enclosed beaters
or rattles struck, scraped or rubbed by hand or struck against another similar
instrument. Excluding zoomusicological instruments and the human voice, the
percussion family is believed to include the oldest musical instruments. In spite of
being a very common term to designate instruments, and to relate them to their
players, the percussionists, percussion is not a systematic classificatory category of
instruments, as described by the scientific field of organology. It is shown below
that percussion instruments may belong to the organological classes
of idiophone, membranophone, aerophone and chordophone.
String
instruments
are musical instruments that produce sound
from vibrating strings when a performer plays or sounds the strings in some
manner.
Musicians play some string instruments, like guitars, by plucking the strings with
their fingers or a plectrum (pick), and others by hitting the strings with a light
wooden hammer or by rubbing the strings with a bow, like violins. In
some keyboard instruments, such as the harpsichord, the musician presses a key
that plucks the string. Other musical instruments generate sound by striking the
string.
With bowed instruments, the player pulls a rosined horsehair bow across the
strings, causing them to vibrate. With a hurdy-gurdy, the musician cranks a wheel
whose rosined edge touches the strings.
Brass instruments is a musical instrument that produces sound by
sympathetic vibration of air in a tubular resonator in sympathy with the vibration
of the player's lips. Brass instruments are also called labrosones or labrophones,
from Latin and Greek elements meaning 'lip' and 'sound'.
There are several factors involved in producing different pitches on a brass
instrument. Slides, valves, crooks (though they are rarely used today), or keys are
used to change vibratory length of tubing, thus changing the available harmonic
series, while the player's embouchure, lip tension and air flow serve to select the
specific harmonic produced from the available series.
