Sound board (music)

As a body is called the resonant body of a musical instrument. It is necessary for the amplification (and hence audibility and carrying capacity ) of the generated tone. He is also responsible for its vibration characteristics essential for the individual sound of an instrument.

Instruments

The construction of the body is different depending on the instrument or instrument group.

Chordophones ( string instruments )

For stringed instruments ( Chordophonen ) the vibration of the strings is usually taken over a bridge and transferred to the body. The relatively large area of the body transfers the vibration to the air and therefore makes the sound only audible. It is important in this sense that the body made of very schwingfähigem material and is built so that all played on the strings tones are optimally recorded and amplified.

The body of a stringed instrument usually consists of several parts, which are generally referred to as a ceiling, sides and bottom.

Stringed instruments include the members of the violin family, viols, lutes, guitars, piano, harpsichord, harp and dulcimer.

Aerophones ( wind instruments, for example )

When wind instruments ( aerophones ), the body is usually a tube in which stimulated the instrument mouthpiece, a column of air vibrates. Depending on the instrument type, the tube length by tone holes or flaps can be changed or the frequency can be multiplied by overblowing.

The aerophones include brass instruments, woodwind instruments and organs.

Musical instruments without body

Since then, there is the possibility to amplify the sound of instruments electronically, this method can make the sound box unnecessary. Popular examples of this are electric guitars, basses, electric pianos or e- violins could do without technically on the part of the body, but mostly kept him from optical and game reasons. Since the advent of electronically amplified instruments are called classical, ie provided with a resonator acoustic instruments (for example, acoustic guitar, unlike the electric guitar ).
