What is definition tone color?

Tone color, also known as timbre, is the characteristic sound quality produced by a particular instrument or voice. It is the unique way that individual instruments and voices sound, which allows them to be distinguished from each other even when playing the same pitch and volume. Tone color is determined by a combination of factors such as the shape and size of the instrument, the materials it is made from, and the way in which it is played or sung. It is an important element of music composition, as it can add depth and complexity to a piece and convey emotions and moods to the listener.
