At the beginning of the classical period still there can be seen Bach’s effects so early examples bassoon still was continued to use as a bass line but with 3 great musicians Haydn, Mozart and Beethoven created their own styles and gave more importance for changing orchestral structure. With the changing orchestral structure, we can understand that in this period orchestra became very important and the number of the orchestra members was increased. And also piano took place in orchestra rather than harpsichord. If we talk about the instrumentation, it was very important and for the achieving good so sound quality all of the groups promoted with each other. Wind instruments are usually used as a duo, at the end of the period this number increased to three in some groups for example Beethoven’s symphony no. 9, symphony No. 5. In addition to this strings were balanced with woodwinds in terms of music stands.
If we talk about the woodwinds, we can say Bassoon has very important place in winds family in orchestra and bassoon was a good supporter for all of the woodwinds especially oboes. In my symphonies and concertos composers preferred to promote winds with 2 or more bassoons. Other than the usages of the bassoon in orchestra, in this period composers composed many solo pieces such as Mozart Bassoon Concerto and many ensemble pieces such as Beethoven’s Trio Sonata for Flute, Bassoon and Piano. The most important compositions, which were composed for solo chamber music with orchestra are Haydn’s Symphonic Concertante for Oboe, Bassoon, Violin and Cello & Mozart’s Symphonic Concertante for woodwind quartet.
