1. Upper Joint: This is the highest part of the oboe and contains the reed assembly, which produces the instrument's sound.
2. Middle Joint: Located in the middle of the oboe, the middle joint consists of several keys and pads that facilitate playing different notes and controlling the instrument's intonation.
3. Lower Joint: The lower joint is the longest part of the oboe and contains the bell, which projects the sound. It also includes additional keys and pads for playing notes in the lower register.
4. Bocal: The bocal is a short, curved metal tube that connects the upper and middle joints. It helps to regulate intonation and allows for fine adjustments to the instrument's pitch.
5. Reed: The reed is the most crucial part of an oboe, as it produces the sound when air is blown into the instrument. It is made from a thin piece of cane and attached to the upper joint.
