Moeck ROTTENBURGH 4200

A Modernized "Rottenburgh": Baroque Tradition and Acoustic Innovations

This "Rottenburgh" bass recorder is rooted in the spirit of Baroque instruments while adopting a decidedly modern approach to design. The stated goal is clear: to start from an already high-performing base and push it further through adjustments in internal geometry and ergonomics. This includes work on the air path, the bore (the internal profile of the body), and the mechanical stability of the keywork to achieve a more consistent, expressive, and comfortable instrument for daily use.

For Whom and in Which Styles?

Designed for musicians seeking a full low register and solid projection, this bass recorder is very suitable for Baroque practices (consort, chamber music), but also for contemporary repertoires, advanced pedagogy, and ensembles (recorder orchestras, early music, new creations). The Baroque fingering promotes widely used intonation and fingering coherence in teaching and ensemble playing. Thanks to its reportedly easier handling, it is suitable both for an intermediate level player looking to advance and for an advanced musician seeking a stable, nuanced, and responsive instrument.

Sound and Design

The design emphasizes a stable air column (the "hold" of breath within the instrument) to offer a significant dynamic potential and to limit "hoarseness" (a muffled or saturated sound). Several elements are optimized: an improved acoustic center, a curved conical windway (guided air path), a narrower air entry and a wider air exit, as well as an optimized underside of the labium (the key area for sound emission on a recorder). The improved bore aims for a pure and balanced timbre across all registers, with an even richer low register and a clearer high register. The natural maple body generally provides a warm sound and good articulation clarity while maintaining beautiful homogeneity between notes.

On the ergonomics side, the instrument features a new stable key system, easy handling, and muffled key noises, crucial points on a bass recorder where the keywork plays a central role. The double holes for C/C sharp and D/D sharp facilitate fingerings and contribute to the accuracy of accidentals, an asset for intonation and fluidity of passages.
