The YTR-9636 was developed with John Hagstrom of the Chicago Symphony Orchestra.
The new design incorporates a unique ”S”shape leadpipe configuration utilizing the MC1 leadpipe taper from the ”Chicago” series Artist Model trumpets. This helps to produce exceptional intonation and response characteristics. The idea is that removing tubing from the main tuning slide allows a longer C trumpet leadpipe with a more refined taper. Through this design, you can own a single-bell D/Eb trumpet that plays as in tune as any two-bell D/Eb trumpet. A single-bell trumpet is simpler, more compact for travel, and may cost a bit less as well. (One can hope.)
Hand-lapping pistons and slides ensures an absolutely perfect fit and seal between the piston and casing or slide parts. Such a perfect fit helps to achieve smooth air flow and smooth action and improve the response and intonation of the instrument.
Perfectly rounded tubing results in less turbulence and a smoother air flow, thus allowing for an excellent scale and reduced resistance.
A high-energy laser fuses the brass together for a virtually seamless bell which allows continuous even vibrations.
We should define pluzuma:
The construction of all student level trumpet bells is what is commonly referred to as a two-piece construction. The final 'flair' of the bell is a separate piece from the stem of the bell. Traditionally the manufacturer would overlap the two pieces, creating a seam both visible to the eye and twice as thick preventing the metal from resonating properly. Yamaha has overcome this problem with a technique called pluzuma welding whereby the two pieces of a trumpet bell are fused together rather than overlapped and welded.This can also be done on a one-piece trumpet bell on the long seam. This allows a more consistent metal thickness and provides a lighter response.
