The Bassoon, like the oboe is a double reed. It has a unique characteristic sound that blends with many instruments. It works especially with cello due to it's similar color and can bring out the "grainy" sound out of the cello timbre. It's dynamic spectrum is not as pronounced as the oboe, but it does get considerably thin in its upper register, and should be avoided in church orchestration due to a lack of projection and the ability of the average church musician. In addition, few churches do have access to a bassoon, and therefore cues should be included in similar instruments whenever possible.
As with the oboe, the lower notes are very reedy, though the sound is less abrasive, due in part to the low frequency.
In a woodwind quintet, the bassoon often serves as the bass instrument.
