Yamaha YEP-321 Series 4-Valve Euphonium
The Yamaha YEP-321 Euphonium features a small shank receiver with a .571 inch bore for easy tone production and response for the advancing student. The 4 nickel-plated top action valves offer excellent, quick action. The YEP-321 includes a hard case, small shank mouthpiece and valve oil.

The YEP-321 Series is one of the most popular models with advancing players and band directors.

Honed Valves
The precise fit between valve casings and pistons after honing means no air leakage.

Pressure Formed Tubing
Perfectly rounded tubing results in less turbulence and a smoother air flow, allowing for an excellent scale and reduced resistance.

Laser-Fused Pluzuma Welded Bell
A high-energy laser fuses the brass together for a virtually seamless bell, which allows continuous even vibrations.

The excellent intonation of the YEP-321 helps to foster a feel for correct pitch, especially in beginning players.

The responsiveness of the YEP-321 assists beginning players in learning the phrasing of the euphonium.

All Yamaha brass instruments come with a limited 5-year warranty.

"Great Intermediate Horn"

I've had my horn for almost three years now and it is a great horn. The valves work pretty smoothly. Just oil it regularly - It does feel a little tight and isn't as free blowing as other intermediate horns, but it still is free blowing. The high range is fairly easy to obtain on this and the low range is's a little hard to control on this horn. THe biggest complaints I have about this horn is that it doesn't have a large shank receiver like some other intermediate euphoniums, and the metal is a bit thin, so it dents fairly easily. Overall, the horn is great for the High School student who plans to be a music major in college.

"The Best In My Point of View"

I played on Conn, King, Yamaha, and Jupiter. The Yamaha is constructed solid. The high notes have good tone and the low notes does also. I dropped this on a concrete floor and it hit the bottom of the euphonium. There was no dent. The brass is a little thicker than it's competitors but the sound is outstanding. I have mine for 15 years and it still is in one piece and the maintenance is very low.

"Great Value, great horn"

This horn is wonderfully dark sounding with an incredible low range. I personally play with a Schilke 51DGP and love the tone I can get. The one tone complaint I have is that above the High f it gets thin sounding, otherwise wonderful. I have a range of almost five octaves on this horn and can produce most any style of music I wish. I have played three of these horns, and they all had almost identical tones and feels once broken in. Overall a wonderful Euphonium for the high school and advanced middle school euphonium player.

"Very good instrument, Great tone Quality and Playibility."

The YEP-321 is a very good quality instrument. The 321 has great tone and ease of blowing. It easily pumps out the notes without too much effort. I have a 1969 YEP-321 #000003, and it is still a "top dog" instrument. This instrument will last you forever, as long as you take care of it. I would definitely recommend this instrument to anyone. It has a few problems with it, but is still very good. Some of the notes are a little stuffy, but time can take care of that. Overall this is a 4-5 (out of 5) instrument.

"Good step-up horn for the Intermediate Player"

This horn is a great step up from any student horn. It keeps the receiver small so the small shank mouthpiece can be retained. It gets the player used to using more air without winding them right off the bat. The pistons are large, which provides for a great full tone, but is a little difficult on young players or those with small hands. Though, with proper technique, it's very easy to adapt to. (The proper finger technique/positioning is also very important as if straight fingers are used, the valves will begin to stick due to being pushed against the casings awkwardly.) I use a Bowman BB1 mouthpiece, and I love the rich tone, though the articulation gets a little muddy with it. (Standard 6.5ALs don't have this problem) I have found that the first slide is flat, but that's probably because my pitch centre is naturally flat (especially with the Bowman). The horn has served me well, though I'm looking to upgrade to the Besson Prestige within the year as it suits my needs more efficiently. I bought my horn around a year after my high school bought one. The horn at the high school has deteriorated rather quickly as students tend to mistreat instruments. My horn, however, is still like-new, minus a couple insignificant scratches most people tell me I'm imagining, though I know they're there. If you take good care of this horn, as with any instrument, it will last you a very very long time.

My parents bought me this horn as a gift. when i got it i had been playing for 2 years on a 3-valve at my school. when i first played this amazing insterment in 8th grade i was thrilled to have a horn that worked, and played with a good dark tone quality! i have been playing on my Yamaha for about 7 months now. having this horn helped get me through many auditions, like Solo and Ensemble, All Disterict, and my Douglas Anderson try-outs. Lets just say i highly recommed this horn;)

"best for the price"

This euphonium was fantastic for me. I am a high school student and I was looking to get my own horn for such things as college auditions and such and I bought this in my junior year and it has served me very well. The only advice I give on this horn is buy a better mouthpiece for it. If you are upgrading enough to buy this horn then get a pro mouthpiece. Must buy for any advancing high schooler or lower level professional.

I've owned two YEP-321S euphoniums since 1994 or so--the first one had some defects and was replaced under warranty, but the replacement instrument Yamaha sent is simply outstanding and I consider it irreplaceable. I have played the YEP-321S through college and in many community bands through the years, and this fine instrument has served me flawlessly, always meeting any performance demands I have placed upon it. It still looks like new, as well. In addition to looking great, the silverplate gives this instrument immediate response; it speaks easier than the lacquered versions that I have auditioned. My teachers, fellow performers, and audiences have all given rave reviews to the wonderful sound of this Yamaha; you can create a tone quality ranging anywhere from melodiously dark to stridently brassy--the only limiting factor is you and your technique. While the included Yamaha 48 mouthpiece is well made and certainly adequate, the Schilke 51D really opens up the dynamic range and low register of this instrument and is highly recommended, giving the player an unmistakable and characteristic euphonium sound that's also never muddled or "woofy". Yes, the Yamaha seems pricey compared to competing models, but it's made well enough to last a lifetime--and to be enjoyed for a lifetime--in the hands of a caring player, thus making it an outstanding value.

I have played on four separate horns of this model, and all have been delightfully easy and free-blowing. The low register is amazingly clear and easy to play. The valve mechanisms are reliable and sturdy. I have played several competing models such as Jupiter's 4-valve intermediate horn and one from King, and the Yamaha has shown to clearly be the best horn in its class. Although it is pricier on average than the competition, it is well worth the extra money, as it is a quality horn for any player, whether beginning or professional. Many band directors will not recommend a horn like the Yamaha to beginning band students due to air resistance and stiff valve mechanisms, but I started out playing a YEP 321, and have been playing them ever since. I attribute my moderate musical success to the playability and quality of this horn. However, it does dent and scratch fairly easily, so be sure to properly keep care of it. Overall, this horn is an excellent choice.

"YEP-321 Best horn in it's price range"

I'm retired from an Army Reserve Band, and we had Yamaha YEP-321 horns. Unfortunately when I retired from the band I had to turn mine in leaving me with only my old 3 valve horn from High school, which was fine for marching with FD bands, but when I got back into playing with a concert band I really needed that 4th valve. The YEP-321 was the first one I looked at, and wound up being the best horn I tried in it's price range. So I've bought myself a YEP-321S. For those that complain that the horn has thin metal that dents easily, well the thickness of the metal effects the sound, if it were made heavier it wouldn't sound as nice. We had 4 of these at the reserve center, and none of them in the 15 years I played with the band had sustained any major damage. It's all a matter of taking care with them.
