What is meant by 'timbre' in music?

The term 'timbre' in music refers to the quality or color of the sound, which distinguishes different types of sound production, such as different musical instruments or voices. Timbre allows us to identify a sound source even if the pitch and volume are the same. For example, the sound of a flute is distinctly different from that of a trumpet, even if they are playing the same note at the same loudness; this uniqueness is due to their different timbres. Understanding timbre is essential for musicians and composers, as it contributes to the overall texture and emotional impact of a piece.
