Chord sounds are divided into 2 groups: wound and compound. Wounded chords are a group of chords in which sound is produced by striking the vibrating agent with a finger or mallet. Compound chords are a family of chords. With a load for the strings and a resonator that are integral parts of the instrument.
Wind instruments
Wind instruments are instruments in which the sound is formed by blowing into an object. They often put holes in this object. By holding and releasing these holes, the desired sound comes out of the instrument. Wind instruments were among the first musical instruments that were made by human hands. Humans of previous centuries had learned that by blowing into cones, leaves, or even animal horns, they could produce a loud and horn-like sound. With this knowledge, they began to make the current wind instruments. which is divided into two groups, wooden and brass, in terms of construction and how to produce sound. In addition, the term "wooden" or "brass" does not mean what kind of instrument it is made of. Rather, this classification is based on the way and method of producing sound in their mouths. For example, flute is one of the woodwind instruments. Of course, its body is made of metal.
Percussion instruments
