Details of Features and Benefits

Drelinger's Patented Optikut

Optikut Diagram

Benefit: Provides the smoothest flow of air by eliminating solder joint within the blow hole.

Karritium® Precious Metal

Karritium Metal

Benefit: A precious metal tube formulation including silver and gold, developed by Drelinger, based on acoustical merit.

Introducing SuprSilver 97TM Precious Metal with Germanium

SuprSilver 97 is Drelinger's trade name for an extremely pure silver, 97% pure, plus Germanium, versus the 92.5% of sterling. We have also created a cold working process that makes it significantly harder than our conventional sterling silver tube.

The result is a sound much like sterling with the added benefit of the perception of increased colours of sound in the top octave.

Drelinger's No-Stretch FitTM

Cross-section of headjoint fitted with Perfect-Match®.  
Benefit: Stretching has been eliminated so that headjoint tenon wall and bore -A- and flute body wall and bore -B- are the same.  And there is no need to give us your flute to get the right fit.

What Is No-Slip-Lip®? Most flutists are familiar with that insecure, skidding feeling of having trapped sweat on their embouchure plate. An effective solution is to have the embouchure plate engraved, but that's too costly and burden-some to be accessible to everyone.

Now all that has changed with the introduction of Drelinger Optikut® headjoints. Now every headjoint we make includes an engraved embouchure plate at no extra cost. Available in a variety of designs, it is a special engraving, created to provide security without your being aware its there. It's also beautiful, so it looks as wonderful as it functions. We also offer the gold-lip option which is a hypo-allergenic grade gold placed in the contact area of the embouchure plate.

I saw the diagram of Quiet-Crown and would like to know whats special about It?

A - Bell shaped all precious metal crown is supplied in weights of 3 to 15 grams in order for us to make subtle changes in timbre and/or resistance.
B - The point at which the threads sandwich a layer of DuPonts Teflon® to eliminate loosening from vibrations.
C - The point where the stainless retainer ring is sealed by a latex adhesive to eliminate air leaks and extraneous vibrations.
D - Latex sealant is extended well into cork to secure alignment.
E - Cork is treated to retard the shrinkage of age and to inhibit water retention.
F - Cork is precisely placed and cemented concentric with reflector disc.
G - Reflector disc of sterling, gold*, or platinum*. Back to Product- Top of page.

How do the patented Gold-Air-Reed®* and Platinum-Air-Reed®* features enhance the Optikut® design? The quick response of Modern Style headjoints is of great benefit. This virtue originates from its sharp, steeply angled blow edge. This almost knifelike edge is critical, as it must work optimally without introducing buzzing in the sound. This buzzing, unlike wind noise, is hypothesized to originate from minute blow edge resonances. Drelinger researched this hypothesis by replacing the blow edge section of several silver and gold lip plates with super hard exotic gold and platinum alloys. With these new alloys, virtual feather edges were created without the criticality associated with traditional metals. The innovation that evolved from Drelingers research is named the Gold-Air-Reed® and the Platinum-Air-Reed® (U.S. pat. 5105705). They provide the quickest, cleanest response ever and are available exclusively with all Drelinger Optikut® headjoints. Its precise dimensions and exotic alloy are critical to its performance. As an example of this criticality, the patented Platinum-Air-Reed shown here was engineered to occupy a precisely defined area of the blow edge and riser. If we were to make the platinum material of the air reed any larger, extending into a greater portion of the riser, its effectiveness would be compromised. The science and art of utilizing a specific size and alloy of a precious metal for a dedicated acoustic function is far more important than obtaining the most platinum or gold bullion in a given headjoint. For example, in most applications a 14K gold crown weighing 7 to 8 grams is more musically desirable than a 14K gold crown weighing 10 to 12 grams even though the heavier crown obviously contains a larger amount of gold. The application of this Drelinger design philosophy can be found in our super low mass crowns, Karittium® as well as numerous innovations like the Platinum-Air-Reed® and Gold-Air-Reed®.

After striking blow edge, air is set into oscillation.

Pictured is a cross section of the Platinum-Air-Reed as part of the seamless one piece Optikut lip plate assembly. The arrow shown here reveals a magnified view of Drelinger’s MicroChannel. This MicroChannel, located one on each side of the Platinum-Air-Reed, provides an additional technological refinement to the blow edge. By intersecting the blowing surface, they help facilitate a smoother overtone pattern throughout the octaves.

How does the patented Free-Flo® * work to reduce extraneous wind noise? The standard lip plate, shown (a), illustrates that the mechanically redundant metal directly in front and partially along side the blow edge serves to support the exhaust wind, creating an upward fan-like pattern. Sometimes this type of air pattern results in audible wind noise. In contrast to this, the Free-Flo* design, shown (b), illustrates that the uniquely shaped barrier-free area surrounding the blow edge allows the exhaust wind to cascade in a natural downward pattern, reducing the audibility of wind noise as reported by flutists who prefer it to other designs. We have also found that those with tear drop formation of the upper lip can produce the third octave with greater clarity then with other styles. Back to Product- Top of page.

What Is Drelinger's T•O•O•T•S? T•O•O•T•S functions to dramatically improve your flute's high note intonation and.controllability. It works so well it eliminates most alternate fingerings previously needed to accomplish the same task. Even exotic corrective F# mechanisms need not be considered, as T•O•O•T•S corrects this note along with others. T•O•O•T•S also gives many modern flutes a top octave pitch and timbre that not only more closely matches the lower registers, but also blends more easily with other instruments of the orchestra. T•O•O•T•S is easily installed into your headjoint in place of its crown-cork assembly. T•O•O•T•S is available in four different models to work with the many different makes of flutes and headjoints.

Please note that the T•O•O•T•S series is primarily meant for brands of headjoints other than Drelinger. The Drelinger headjoints incorporate many of the advantages of T•O•O•T•S as part of its design and do not require, in most situations, the addition of this optional feature.Back to Product - Top of page.

New Cathedral Crown Technology

I concluded years ago the need for a less critical and consistent real cork seal clearly has major benefits to achieving optimal headjoint sound.

Simply stated, real cork is as important to headjoint sound as real horsehair is to the bow of a violin. There is no substitute for the distinct sound traditionally identified as that of the cork sealed headjoint. O-ring seals have been used as an alternative to cork, however one of the major issues with O-rings is they alter headjoint sound to a degree where it becomes a different timbre.

There is simply no substitute for the cork’s contribution to sound. However one of corks major issues is its piece-to-piece variability. Variations in elasticity, porosity and resistance to shrinkage vary all over the lot. Additionally the nature of cork requires a compromise between two issues during installation. It must be tight enough to resist loosening from moisture deterioration and loose enough to avoid damping out the vibrancy of the head. In fact, we have seen competent flute technicians who are otherwise totally skillful, perform so-called "routine cork replacement" that did not meet Drelinger standards. Remember, a poorly fit or deteriorated cork can make an otherwise excellent playing head missing quality.

The initial focus of Drelinger’s new Cathedral Crown Technology started with selecting the finest, most consistent natural cork available and making it work correctly, moisture free using a new sealing technology. By eliminating the need for tight cork installation, the cork can be optimized for proper sound without concern for moisture penetration or leakage. In fact, Drelinger guarantees the cork for six years.

In the early 1980’s Drelinger introduced a breakthrough crown/cork assembly which for the first time designed to prevent mechanical loosening of the crown, made provisions for adding additional crown weight and among other benefits also improved cork life by impeding moisture. It is still a current feature on all our headjoints and can be seen on this website. In the almost 30 years that passed since the introduction of the Quiet-Crown™, many manufacturers followed our lead by developing various crown locking mechanisms and methods for adding weight to crowns.

We are now proud to announce a successor to Quiet-Crown which dramatically advances the concept which Quiet-Crown originally put into practice more than a quarter of a century ago. We call this new innovation Cathedral Crown Technology™. The Quiet-Crown will continue to be standard on all Drelinger headjoints. Drelinger’s new Cathedral Crown Technology will be an optional feature on our new headjoints and will be available to retrofit Drelinger headjoints now in use. Later we will offer this innovative technology to owners of other makes of headjoints.

What Is the MaxHeadjoint? The MaxHeadjoint combines our Free-Flo®, and Gold-Air-Reed®, or Platinum-Air-Reed® with a new ergonomic lip rest in one single headjoint design. The multiple benefits of all these patented features has made the MaxHeadjoint one of our most popular models. Back to Product - Top of page.
