Robert Sullivan was Yamaha's main consultant for the NY Series project. Sullivan is an outstanding trumpeter and educator. The project began while he was assistant principal in the New York Philharmonic, and the collaboration was carried out simultaneously as Yamaha developed the CH trumpets in Chicago. The technical secrets learned from the two projects were combined together helping Yamaha learn even more about tonal colors, projection, intonation, and everything else needed to create a truly expressive instrument.

The bell is one of its most important elements. Similar to the CH Series, the wall thickness gradually tapers, thinning as it gets closer to the rim. The flat dome style rim is wider than on most modern trumpet bell rims, which helps hold the sound together even at extreme dynamics. And the seam of the bell is aligned with the braces to improve tonal projection.

The new shape of top and bottom valve caps and the skeletonized interior valve stems contribute greatly to the flexible response of the trumpet.

The braces between the bell, valve casing, and leadpipe are smaller bringing the parts closer together, which gives a natural vibrancy to the entire trumpet.

The 3rd valve slide stopper has been moved to allow extended slide play for a low F or to facilitate alternative fingerings. The C trumpet has an oversized button on the end of the slide to fine-tune the blowing resistance while the Bb has a smaller button.

The leadpipes are based on Bob Malone''s own design (MC2 for C, MB2 for Bb). They are also one of the more crucial components of the trumpets, and you will find that notes slot easily and comfortably in all ranges, with exceptionally accurate intonation and an open feeling response.
