In my research on bassoon, I want to search for bassoon’s history in different periods. First I will give a brief definition of the instrument. Bassoon is a woodwind instrument and is played with double reed. Composers usually use this instrument in the bass and tenor register. It has a register of 3.5 octaves. It is made up of maple and also metal tubes. Its length is 1.3 meters and there are 6 different pieces. 4 of them are wood, 2 of them are helping pieces.
- The Bell (Kalak): Upper piece
- The Bass Joint (Bas & Uzun): The longest left-hand piece
- The Wing Joint (Kanat): The shortest left-hand piece
- The Boot (Çizme): At the bottom of the instrument
- The Bocal (Es Borusu): Metal tube which likes a question mark
- The Reed (Kamış): The double reed
On the other hand I can say bassoon has 3 different tone colors regarding three registers. First one is the bass register starting with Bb and ending again with Bb. This octave has a dark, full and rich timbre. To be able to achieve a good sounding in forte or piano and for the correct intonation, players should have good diaphragm control and good technique. Second is the middle register starting with C(?) and ending with C. These sounds created vocal voices effects in pale, dry, soft and solemn passages. And finally the Upper register is started with D and end with E. Some players can play F, F# and G, however, it is so difficult.
