Brass Sound in Bright 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 every fun and delivers radiant sound that guarantees great vibes at all feel-good events where the unmistakable tone of a brass instrument 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 you can confidently pull out at any occasion where the expensive brass model would rather stay in its gigbag. Its very light weight makes the Classic Cantabile MardiBrass Euphonium the ideal student instrument!

Top-Notch Features!

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

Perfect for On the Go

The MardiBrass instruments are so light they won’t weigh you down during moves or upcoming mountain hikes. 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 evenings.

Take It Easy, Take MardiBrass!

Question by Willig Petra on 04.01.2024

My valves are tight. What do I do?

Answer by Musikhaus Kirstein:

Please refer to the care instructions: https://www.kirstein.de/docs/manuals/pflegehinweis-blasinstrumente-oelen.pdf
You can unscrew the valves at the top and add a little oil (e.g. https://www.kirstein.de/Blasinstrumente-Pflegemittel/La-Tromba-T1-Ventil-Oel-mit-Silikon-65-ml.html). They should then run again.
