- The bassoon's low register requires a large volume of air, and it is important to have the resolve of blowing air as if directing it at your stomach, with an image of sending the air downward and toward the back
- The embouchure should be more vertically open than in the middle register, with stronger lateral pressure, and maximizing the space inside the mouth is the key to producing a resonant low register
- For left-hand key operation, it is important to not lift the thumb away from the keys more than necessary and to slide it smoothly while keeping it in contact with the keys. The pinky should also not be lifted off each time, but rather glide over the rollers
- When adjusting the reed, if the area near the base is too thick, air cannot flow easily, and filing down the center with a round file to remove excess material makes it much easier to produce low notes
In bassoon playing, the low register is the area most players find most challenging. To reliably produce a resonant low register—where the complexity of left-hand key operation, the required air volume, and embouchure adjustments all intertwine—it is essential to understand the concepts first and then put them into practice.
Concepts for a Resonant Low Register: Air, Embouchure, and Oral Cavity Space
To reliably produce a resonant low register on the bassoon, a large volume of air is necessary. Starting from a state of being completely filled with air, maintain the resolve of blowing air as if directing it at your stomach, with an image of sending the air downward and toward the back. The angle of the jaw and the angle of the neck should also be drawn back slightly, and this air direction is used more frequently.
Regarding the embouchure, the key points are that it should be more vertically open than in the middle register, with stronger lateral pressure, and the space inside the mouth should be maximized. Tongue position is also important: lower the root of the tongue, allowing it to settle into the hollow behind the lower teeth, so that the space inside the mouth reaches its maximum.
Left-Hand Key Operation: Smooth and Efficient Movement
The bassoon's low register has densely clustered left-hand keys, and the difficulty lies in having to operate all of them with just the left thumb. Since there are also two keys for the pinky, complex movements are required.
What is important in low register key operation is not lifting the thumb away from the keys more than necessary. Avoid letting it come completely off and instead aim for a motion of sliding it smoothly while keeping it in contact with the keys. For the pinky as well, rather than lifting it off and pressing down again each time, if there is a roller, it is fine to keep your finger touching the roller, and moving it smoothly is essential.
Practical Approaches
To reliably produce a resonant low register, it is important to understand the concepts first, then master them through practical approaches. By implementing specific methods such as reed adjustment, checking the instrument assembly, and setup tips, you will be able to command the low register with confidence.
Reed Adjustment and Instrument Assembly
To make the low register easier to produce, if the base of the reed—the area closest to the wire—is too thick, air cannot flow easily. By filing down the center with a round file to remove excess material, it becomes considerably easier to produce low notes. Also, if the reed opening is too narrow, squeezing the first wire from the sides with pliers will make the airflow much better.
Instrument assembly is also important. Regularly check for sources of air leaks such as peeling cork on the bocal, loose thread on the joints, loose screws on the U-tube, and worn rubber or cork. If the cork is worn down, the best course of action is to take the instrument to a repair shop promptly.
- ① Warm-Up Training: Repeat the low register key operation slowly, then at double speed, to train the thumb
- ② Key Operation Fundamentals: Do not lift the thumb away from the keys more than necessary; slide it smoothly while keeping it in contact. Also aim to glide the pinky over the rollers
- ③ Air and Embouchure Adjustment: From a state of being completely filled with air, maintain an image of sending the air downward and toward the back. Open the embouchure more vertically than in the middle register and maximize the space inside the mouth
- ④ Reed and Instrument Adjustment: Use a round file to remove excess material from the base area. Check the instrument assembly and inspect for any sources of air leaks
To reliably produce a resonant low register on the bassoon, it is important to understand the concepts of a large volume of air, embouchure adjustment, and maximizing the space inside the mouth, and then master them through practical approaches. By performing smooth left-hand key operation, and implementing reed adjustment and instrument assembly checks, you will be able to command the low register with confidence. In bassoon playing, mastering the low register is achieved by comprehensively understanding and practicing the many elements of air, embouchure, key operation, reed adjustment, and instrument assembly, resulting in a reliably resonant low register.
