Musical instruments:

Audible Where was originated in vibrating strings vibrating air columns and vibrating plates and membrane accordingly musical instruments are classified into three main types a string instrument be wind instruments precaution instruments

(a) string instruments consist of stretch strings sound is produced by plucking of strings the strings are tuned to certain frequencies frequent by adjusting tension in them they are further of three types

1. Clipped string type in this instrument string is plugged by fingers example Tanpura sitar guitar guitar etc
2. Board string type in this instrument a string it's played by moving for example voilin Sarangi
3. Struck stream type the string is truck by a stick example santur piano
4. Wind instruments these instruments consist of air column sound is produced bysetting vibrations of air coloumn they are further of different types
5. Free wind type in this instruments free brass reed are vibrated by air the air is either blown or compressed example mouth organ harmonium etc
6. Edge type in this instruments air is blown against and age example flute
7. Read pipes they may consists of single or double rates and also instruments without reads example saxophone clarint basson bluge (without reed)
8. Percussion instruments in these instruments sound is produced by setting vibrations in a stretch membrane example tabla drum dual Mary Gandam assemble lovely etc these instruments sometimes also consists of metal plates which produced sound when they are stuck against each other or with a bitter example Campbell's xylophone etc a glue on the membrane or plate or plucking of string produces vibrations with one fundamental and many overtunes super position of several natural modes of oscillations with different amplitudes and hence intensities characterise different musical instruments we can those distinguish the instruments by their sound production of different notes by musical instruments depends on the creation of stationary views for a stringed instrument such as guitar or sitaram the two ends of the string are fixed depending on where the string is plugged produced looking at the midpoint produces the minimum frequency or the fundamental modes of vibration in wind instruments are air changing in length of air column note can be change in wind instruments leg flute holes can be uncovered to change the vibrations of air column these changes the pattern of nodes and antinodes in practise sound produces is made up of several stationary views having different patterns of nodes and antinodes musicians skill lies stimulating the string for air column to produce the desired mixture of frequencies
