Clarinet itself is black, and even its sound is reminiscent of mysterious black. The flute is silver, with a lonely and cold luster. The oboe is yellow, bright and warm, bringing a gust of smoke. Only the clarinet, as silent as the night, as hidden as the night.
The clarinet, with its soft and deep unique timbre, is just like a lyrical soprano. Clarinet, mysterious and changeable timbre, gentle and elegant tone are the most fascinating. In symphonic music, the brilliant works of clarinet are numerous. In the middle of the minuet movement of Mozart's "Symphony No. 39" and Beethoven's "Symphony No. 8", there are wonderful timbre effects produced by the combination of Clarinet and flute.
