Brass Sound in Vibrant Colors!

Good news for everyone who likes to take their wind instrument out on the town: the Classic Cantabile MardiBrass series is here! Fear of unpleasant tones from temperature changes and worries about dents after lively spontaneous sessions are finally a thing of the past. This indestructible instrument joins in on all the fun and delivers radiant sound that guarantees great vibes at every feel-good event where the unmistakable brass instrument’s tone is essential.

Super Lightweight

Kids, music students, and wind heroes, listen up! This euphonium from the Classic Cantabile MardiBrass line is an attractive instrument perfect for experimenting, inviting you to try new things, and one that will confidently be pulled out at every occasion where the expensive brass model would rather stay in the gigbag. Its very light weight makes the Classic Cantabile MardiBrass Euphonium the ideal student instrument!

Top-Notch Features!

If you think durability and precision can’t go hand in hand, think again. The combination of a tough plastic body with high-quality, corrosion-resistant aluminum valves and brass valve casings makes the Classic Cantabile MardiBrass a truly well-rounded package.

Perfect for On the Go

The MardiBrass instruments are so light they won’t weigh you down during moves or upcoming mountain hikes. But their durability also makes them ideal travel companions. The ABS plastic euphonium doesn’t mind being set down briefly on the beach while the band cools off in the water, and it easily withstands long, lively, damp cabin nights.

Take it Easy, Take MardiBrass!

For this price, the instrument is incredibly good. The weight is very comfortable and you don't get cold fingers in winter. The valves are louder than normal. The tone and tuning are amazingly good. I think the instrument is very suitable for young beginners.

I ordered the plastic euphonium because I wanted to play a lower instrument as well as the trumpet. The instrument was delivered cleanly oiled and with greased slides, ready to play immediately. Great service from Kirstein.
Today I let my euphonium-playing colleagues try out the instrument. They liked the instrument and thought it was great for the price. I'm still practicing myself. But as the instrument responds well, I was able to play some simple pieces in today's rehearsal. I should also mention that a metal mouthpiece is VERY recommendable. Kirstein will be happy to advise you.
I am satisfied

When the euphonium was delivered, I immediately tried it out with curiosity and was initially shocked by the strange sound. It was only when I unlocked the 4th valve on the side that the sound was right. I am very satisfied with the response, the workmanship and the weight.
As I have played in a trombone choir for over 40 years and took my expensive brass horn with me in all weathers, I am now very pleased with this good alternative for outdoor events.
The only pity is the white mouthpiece on the black euphonium, I would have been happier with a black mouthpiece as shown in the description.
Super price performance

Good instrument with an amazingly good sound. Of course, it has limitations in the bass and treble ranges. Super playable in the normal registers and the notes are just right.
I'm really very enthusiastic about this lightweight!
For the price eim hammer!

My Wilson Euph. costs 30 times as much and is much too bad for carnival, etc.. For this the
"plastic part" absolutely. Very good price-performance ratio.

Question by Johannes Terkatz on 13.11.2025

I would like to replace the supplied plastic mouthpiece with a brass one. Which mouthpieces fit?

Answer by Musikhaus Kirstein:

The MardiBrass euphonium generally fits mouthpieces with an L-shaft (12.5mm). The following standard mouthpiece, for example, would be a good combination: https://www.kirstein.de/Mundstuecke-Blechblasinstrumente/Arnolds-Sons-Mundstueck-fuer-Posaune-6-1-2-AL-L.html
