The newest flute available from Brannen Brothers Flutemakers, Inc. is the 15/85 Brögger Flute! This flute is made from an alloy of 15% gold and 85% silver; it offers a unique playing and hearing experience emanating from the world-renowned work of Headjoint Maker Rainer Lafin. Mr. Lafin has used this alloy for many years to create his fine headjoints, and now Brannen-Cooper® flutes are available in the same material.

The Brögger Flute: Our most well-known, popular instrument, this flute combines the traditional fingerings of the Boehm system with the enormous advantages of the Brögger Mekanik™. This mechanism increases the reliability of the keywork and reduces internal friction, allowing keys to be adjusted much more closely to individual preferences. A soldered tonehole flute, the Brögger offers the widest possible range of options, including choice of materials and custom keywork. We are proud to offer the Albert Cooper Orchestral Model as an option on our Brögger flutes.

The Brögger Mekanik™

The Brögger flute is the flute most people are referring to when they speak of a "Brannen-Cooper®" flute.

The Brögger flute is a Boehm system flute that uses a major mechanical modification developed by the Danish flutemaker, Johan Brögger, about 20 years ago. While Boehm flutes have proven themselves remarkably reliable for 150 years, there have always been two problems associated with them that frequently require maintenance:

misadjustment between certain keys in the "main line," e.g., between D and E to F#, or between A to Bb, and

binding problems between the G key and the Bb key on inline flutes.

The Brögger Mekanik™, with its use of non-rotating shafts and full-size back connectors for all main line keys, effectively eliminates these common problems. The resulting flute is noticeably quieter with reduced friction and far less wear to its moving parts.

There are two additional advantages to the Brögger Mekanik™. First, the flutemaker now has the ability to regulate the spring tension of each key independently of any other, thus allowing for a much more even feel for the performer. The second, equally important feature is the increased strength of the mechanism, especially as it applies to accidents in which the flute is dropped. We have now had 15 years of experience with this mechanism, and our experience bears out this statement in the most remarkable fashion.

This is also the Brannen-Cooper flute that offers the greatest number of options. Most of the options usually requested are listed on the optionspage. We also offer the Albert Cooper Orchestral Model as an option on our Brögger flutes. We have designed and built an incredible variety of other options at the request of individual customers. If the option you would truly like to have is not listed, please feel free to call us, and we will direct you to speak with the appropriate member of our technical staff.

When we first brought the Brögger flute to market, many repair people were hesitant to work on it because they simply were not familiar with it. Now, most technicians, who routinely work on professional-quality instruments, have come to endorse the Brögger Mekanik™ with great enthusiasm, realizing that it is extremely stable and can be worked on easily.

Most importantly, it is the players who have made this instrument the most sought after professional flute on the market today. They have come to enjoy its increased reliability, the livelier, uniform action of its keys, and the marvelous comfort that it offers.

B footjoint
C footjoint
D footjoint
B/C convertible footjoint: A cleverly-designed, 3- piece footjoint that can be used as either a B or a C footjoint. It is designed for the flutist who prefers a C footjoint, but sometimes needs a low B.

D# Roller:
This roller facilitates movement between the D#, C#, and C keys on the footjoint.

C# Trill:
An additional trill key that moves several left hand fingering combinations to the right hand and simplifies a number of trills. Please see C# trill for a more complete description of the uses and benefits of this key.

Split E Mechanism:
An additional mechanism that provides a more secure high E natural and improves its articulation. It does not alter the pitch of any notes.

Lower G Insert:
A much less expensive alternative to the Split E mechanism, this insert also provides a more secure high E natural. Some players notice a slight flattening of the A natural in the first and second octaves.

Key Extensions:
These extensions allow a flutist with hand problems to re-configure the keys in more comfortable ways.

Customized Keywork:
An almost endless variety of key alterations designed to meet an individual flutist's needs when key extensions are not the appropriate solution. Designs such as our angled footjoint cluster have helped make the flute more comfortable for many flutists.

Engraved Keywork:
Decorative engraving is available for key cups. Please contact the company for available designs.
