The same song can sound completely different when performed by two different singers or played by two different instruments. If the key is the same, the tempo is the same, and the articulation is the same, what is it that accounts for these differences? The answer is timbre, which refers to the character of a sound-the unique colour or tone of a singer’s voice, or the sound quality of a particular instrument. In this lesson, the Tiny Tigers explored a variety of timbres in activities that built their capacity for musical appreciation and expression. They identified and discriminated sounds, articulated personal sound preferences, and created specific sounds to express themselves musically.
