Moeck ROTTENBURGH 4520

Rottenburgh: a modern evolution of a classic model by Moeck

There is always room for improvement, even with an already accomplished instrument: this is exactly the spirit of this Moeck Rottenburgh. The model has been completely redesigned by incorporating acoustic design innovations to increase stability, attack precision, and dynamic range. Within the Rottenburgh range, this bass recorder aims for a more reliable response and a more nuanced sound, while maintaining the manufacturing quality associated with the brand.

Who this bass recorder is for

This bass recorder is intended for intermediate to advanced musicians (and demanding ensembles) seeking an expressive instrument capable of supporting nuanced playing across the entire range. It is perfectly suited for Baroque music (Baroque fingering), but also for early music in a broader sense, ensembles, contemporary projects, and any situation where the bass must remain clear, stable, and articulated.

Sound and design

The acoustic design has been thoroughly refined: improved acoustic center, curved conical windway, narrower air entry, wider air exit, and optimized underside of the labium. The result: a stable air column, a significant dynamic potential, and better resistance to "hoarseness" (the recorder maintains clarity even when pushing the sound). The improved bore promotes a pure and balanced timbre across all registers, with an even more resonant lower register and an even clearer upper register. The natural maple body provides a sober aesthetic and a warm response, while the keywork contributes to a more precise attack and more consistent sound production.

Recommended compatible accessories

For routine maintenance and longevity, it is advisable to have a spare cork grease (essential for preserving the airtightness and flexibility of the joints) as well as an additional cloth dedicated to drying after playing. Since the instrument is already supplied with the essentials, these extras remain optional.
