timbre
Timbre is the quality of sound that allows us to identify the object that produces the sound (different voices and instruments). It depends on the shape of the object, the material from which it is made and the way the sound is made. The result is a complex wave composed of a fundamental frequency and its harmonics.
STRING
The sound is produced by the vibration of one or more strings. The pitch of sound depends on the length, thickness and tension of the string. The longer, thicker and looser the string the lower the sound, and vice versa. We divide these instruments into three groups:
BOWED STRING
String instruments in which the sound is produced when the strings vibrate because they are rubbed with a bow. All of them have 4 strings and a very similar shape.
Lorem ipsum dolor sit amet
PLUCKED STRING
String instruments in which the sound is produced when the strings vibrate because they are pulled and released with the fingers or with a pick / plectrum..
HARP
GUITAR
VIHUELA
STRUCKED STRING
String instruments in which the sound is produced when the strings vibrate because they are hit with small hammers activated by a keyboard.
Piano: it has 88 keys which cover more than seven octaves. It has the widest range of notes of any instrument.

wind instruments
woodwind
Wind instruments which used to be made of wood and they produce sound by blowing into the mouthpiece. The pitch of sound depends on the length of the tube that can be changed by opening or closing holes. They have three types of mouthpiece:..
MOUTHPIECE WOODWIND INSTRUMENTS
Fipple: the sound is produced by the vibration of the air blown against an edge. E.g. recorder, transverse flute. Single reed: the sound is produced by the vibration of one cane as air is blown between the cane and the mouthpiece. E.g. clarinet, saxophone. Double reed: the sound is produced by the vibration of two canes as air is blown between both canes. E.g. oboe, bassoon.
BRASS
Wind instruments which are usually made of metal and they produce sound by buzzing the lips against the mouthpiece. They have a cup mouthpiece and a rolled tube which ends into a bell-like shape. The pitch of sound depends on the tension of the lips and on the length of the tube that can be changed by means of valves or slides.

PERCUSSION
Pitched or tuned percussion: percussion instruments in which we can play notes and melodies.
