Holton B302R Euphonium

"The Holton B302R euphonium is the same as a Yamaha 321, just made for Holton by Yamaha. This is one of the most popular euphonium horns available, and for good reason: it has excellent pitch, tone, and response throughout the range. The 11 inch bell gives it a focus that projects well with a full, clear sound. I also have a Besson 968, which, of the larger compensating euphoniums, plays the closest to the B302R that I could find. The Holton has a slightly smaller bore than the Besson Euphonium, so it has more of a French Horn quality to the sound, which I like. Both the Holton and Besson are terrific euphoniums! Switching between the non-compensating Holton and the compensating Besson is not a problem, there are just some fingering changes in the low register and a few tuning adjustments in the upper range. A larger mouthpiece on the Holton will go a long way towards getting more of the feel and tone of a larger bore compensating euphonium. It is a very flexible horn and a delight to play! Although often listed as a student horn, in choosing a euphonium, as far as I am concerned it is a first class professional quality instrument."

This instrument review was with a Monette BT 2 L  mouthpiece.

What is a compensating euphonium?

A compensating euphonium is a British design that "compensates" for the increasingly sharp pitch encountered in the low register. There is a second set of tubing for each valve that opens only when the fourth valve is engaged. This extra tubing corrects the pitch when playing low, without altering the tuning of the mid and upper registers. This allows the use of the mid-range fingerings (plus the fourth valve) to play low notes. On non-compensating instruments, low notes with the fourth valve are usually fingered one half step lower to compensate for the sharper pitch from low Eb down. This leaves low B without a fingering. With the compensating system, there is a fingering for low B, so you get a fully chromatic low range with only four valves. Non-compensating instruments, especially tubas, often add a fifth valve to correct this tuning problem.
