Music cannot be music without the most important things, the timbre, the voice and the instruments. Let's start with the stamp. Timbre is known as the fourth property of music. This explains the notable differences in the sound quality of the instruments. Timbre is influenced by the size, shape and proportions of the instrument, the material it is made of and how the vibration is produced. The voice and instrument have limited melodic range and dynamic range. The voice is the most natural and widely used musical instrument. Each voice has quality, character and range. From highest to lowest we have soprano, mezzo-soprano and contralto in females. In males we have tenor, baritone and bass. The human voice has been used as a model for instrument makers and musicians to duplicate its beauty, cost, and ability to produce vibrato. On the other hand, instruments are a mechanism that generates musical vibrations and launches into the air. It is classified into four categories: aerophones (produces music using air), chordophones (produces sound by vibrating strings between two points), idiophones (produces sound from the instrument itself) and membranophones (sound produced by stretched strings
