Music cannot be music without the most important elements, timbre, voice and instruments. Let's start with the stamp. Timbre is known as the fourth property of music. It accounts for the striking differences in the sound quality of the instruments. Timbre is influenced by the size, shape and proportions of the instrument, the material the instrument is made from and the manner in which 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 a quality, character and range. From highest to lowest, we have soprano, mezzo-soprano and alto in females. For men we have tenor, baritone and bass. The human voice has been used as a model by instrument makers and musicians to replicate its beauty, cost, and ability to produce vibrato. On the other hand, instruments are a mechanism that generates musical vibrations and launches itself into the air. It is classified into four categories: aerophones (producing music from the air), chordophones (producing sound by vibrating strings between two points), idiophones (producing sound from the instrument itself) and membranophones (the sound produced from stretched strings).
