Instrumental Duet Bassoon,Instrumental Duet,Piano - Level 4 - Digital Download SKU: A0.889285 Composed by Mary Jane Lang. 20th Century,Contemporary,Standards. Score and parts. 15 pages. MaryJaneLang #2059. Published by MaryJaneLang (A0.889285). Mood Swings is a novelty piece for the clown of the orchestra, the bassoon! It is scored for bassoon and piano. It is happy-go-lucky in nature with a mock-noble (grandiose, if you will) middle part for general contrast. This will be a fun piece for the young bassoon student, as well as a novelty piece for any occasion. Everyone knows that the musical performer (soloist, especially) must be a master of mood swings, acting through the medium of his or her instrument. On the other hand, artistic temperaments with mood swings are generally scorned by society. We shall see!
