YTR-9445CHS

The "Chicago" Series

The Chicago Series was developed in close cooperation with John Hagstrom of the Chicago Symphony Orchestra. A fusion of traditional style and state-of-the-art design achieves a comfortable resistance and a tone that is both brilliant and deep. The C and Bb trumpets have consistently outstanding feel and playability throughout their ranges, so switching instruments is smooth and seamless.

Valve Casing

Based on new findings acquired through research into vintage trumpets, the dimensions and thickness of parts of the valve casing have been revised for the 2019 model. The refined valve casing and lightweight pistons work together to deliver significantly improved response for even greater clarity in detailed passages.

Bell Design

The bell features a design that is narrower toward the valve casing, and a square-cornered bell bow that provides the performer with a more balanced resistance. This results in a more "three-dimensional" sound, with a strong tonal core that improves upper register playability. The YTR-9445CHS bell has been changed from the previous YS4 type to a YS4s type with a different bell tail shape. Combined with the MC1 leadpipe, this results in even greater pitch accuracy.

Main Tuning Slide

For the 2019 model revision, a square main tuning slide that provides enhanced overall playing feel and tonal balance has been adopted in the YTR-9335CHS and YTR-9445CHS.

Water Key and Water Key Cork

A redesigned water key contributes to improved resonance in the YTR-9445CHS. The weight distribution of the water key arm and saddle improve playability and response while enhancing high resister accessibility. A new rubber cork material* that is more resistant to deterioration over time is used for the water key seal. These modifications contribute to improved definition of sound, projection, and response.

* Rubber cork: Cork particles are evenly distributed through a synthetic rubber, achieving greater compression resilience than conventional cork.

Reversed Tuning Slide

The leadpipes are based on Bob Malone's own design, which on the chicago C trumpet is a long taper that ends in a hidden, reversed tuning slide. These leadpipes are largely responsible for the tonal expressivity of the trumpets, and you will find that notes slot easily and comfortably in all ranges, with exceptionally accurate intonation.

French Bead

Unlike traditional methods where a round rim curl is used, a French bead is an advanced technique that matches the curl to the shape of a semi-cylindrical rim and is characterized by improved feedback of sound to the performer.

Leadpipe

Utilizing a leadpipe that is thicker than current designs, an original style Malone Pipe™ (MC1), and a lighter mouthpiece receiver, tone and response have been improved while providing the performer with ideal blowing resistance. Also the finger hook is not soldered to the leadpipe. You will hear and feel the difference in tone quality and response.

Malone Pipe™

Based on leadpipes designed by renowned brass instrument artisan Bob Malone, the Malone Pipe™ is available in several keys, offering quick response, superior intonation and unparalleled evenness of tone. Originally a trumpet player himself, Bob Malone opened his own custom brass shop in Los Angeles in 1983. Trumpeters flocked to his shop to have him personally customize their horns. His original leadpipe design has enjoyed wide acclaim and is still held in high regard among trumpet players. Since Bob joined Yamaha’s Research and Development team in 2001, his Malone Pipe™ design has made its way into a number of Xeno Artist models and Custom series instruments. Rich and brilliant tone with excellent projection, the Malone Pipe™ brings total expression to your music.

Brace Design & Position

The design of the bell braces achieves quick response with a brilliant, well-centered tone. Although the position of the YTR-9335CHS tuning slide brace is unique for a Bb instrument, the distance between the mouthpiece receiver and tuning slide brace on the YTR-9335CHS and YTR-9445CHS are similar when the slide is extended for tuning, so that consistent playability is achieved when switching between Bb and C trumpets.

1st Valve Slide

The first valve side has a special brace for a stronger focus to the core of the tone, resulting in unparalleled definition and clarity.

3rd Valve Slide

The 3rd valve slide stopper position is designed to allow the slide to be extended sufficiently to achieve accurate low F pitch. The button at the tip of the slide and the quarter circle stopper ring help to fine-tune the playing resistance for superior comfort and playability.

Slide Stopper

The slide stopper is designed to prevent the first and third valve slides from falling off. The slide stopper is made of silicone rubber that will not harm the finish. Providing both strength and elasticity, it can remain attached to the instrument during performance. (Length: 12 cm)

Case

TRC-801E double case that can be carried in your hand, over your shoulder, or like a backpack.

Development Artist

John Hagstrom （Chicago Symphony Orchestra)

John Hagstrom has been a member of the Chicago Symphony Orchestra's trumpet section since 1996, when he won the audition for fourth trumpet. A year later, he won the second trumpet position, carrying on the tradition of brass section teamwork for which the CSO is famous. Prior to joining the Orchestra, he was principal trumpet of the Wichita Symphony Orchestra in Kansas, and served as assistant professor of trumpet at Wichita State University.

A native Chicagoan, Hagstrom grew up listening to the CSO. Five years of study at the Eastman School of Music were followed by six years in "The President's Own" United States Marine Band in Washington, D.C., where he spent three of those years as principal trumpet. His many solo appearances with the band included four national concert tours and the Camp David wedding of President Bush's daughter, Dorothy.

Recent recordings featuring John Hagstrom include his performance of the Bellini Oboe Concerto and the Sachse Concertino with the Chicago Brass Choir. He also can be heard as lead trumpet on Daniel Barenboim's recording on the Teldec label entitled 'Tribute to Ellington'.
