“Happy Easy Wind Instrument” is a relaxed sketch performed only by clarinet and Bassoon duet. The two woodwind timbre are one high and one low, one bright and one dark, like two old friends chatting in the afternoon-clarinet throws out the topic briskly, Bassoon catches it with simple and honest bass, occasionally amusing each other and occasionally marching in unison. The melody lines are concise and stretched, without complex textures or heavy emotions, only the warm texture unique to wooden pipes flows freely in the air. The whole song creates a sense of “no need to think about anything”, like an afternoon when the sun shines on a park bench and leaves rustle. It is suitable to be used as a relaxing daily paragraph of film and TV series, a warm animation scene, a light transition of commercial films or any picture that needs “no pressure to accompany. Easy, pleasant, warm, playful.
