Aulos 533B Symphony Bass Recorder
The Aulos 533B Symphony Bass Recorder is a professional-standard bass recorder designed for ensemble and solo performance. It features a bocal-style pipe and a durable ABS resin construction, offering a reliable alternative to traditional wooden instruments.

Overview and Construction
The Aulos 533B Symphony Bass Recorder is engineered for durability and sonic precision. Constructed from high-quality ABS resin, the instrument is resistant to moisture damage, addressing the common issue of splitting found in wooden recorders. This material choice ensures the instrument is easy to maintain and clean, making it suitable for frequent use in varying environmental conditions.
The recorder is built in three distinct sections, facilitating easy assembly and thorough cleaning. It utilises a bocal-style pipe (crook) to provide a comfortable playing position for the performer, which is essential for an instrument of this size. The design is finished in a professional aesthetic consistent with the Aulos Symphony series.
Design Features and Playability
Several specific design elements contribute to the 533B's performance capabilities:
- Curved Windway: This feature provides a degree of resistance that allows for better volume control and projection across all registers.
- Concave Bell: The footjoint is designed with a concave bell, which is specifically intended to enhance the resonance of the lower notes.
- Outstanding Response: The internal bore design ensures a quick and reliable response to the player's breath, aiding in technical passages.

Sound Character
The Aulos 533B is noted for its full, warm tone. Despite being made of synthetic resin, it is designed to mimic the acoustic properties of wood, providing a rich sound suitable for both performance venues and educational settings. The instrument provides a consistent resonance that allows it to blend effectively within a recorder consort while maintaining enough presence for solo work.
Maintenance and Accessories
As a three-piece instrument, the 533B is straightforward to maintain. The included microfibre cleaning cloth and dedicated cleaning pouch allow players to remove moisture from the bore after use. Because it is made of ABS resin, it does not require the intensive oiling or humidity control necessary for wooden counterparts. The instrument is supplied with a carry bag to ensure safe transport between venues.
Comparison and Suitability
The Aulos 533B occupies a specific niche between entry-level plastic recorders like the Percussion Plus PP993 Descant and high-end professional wooden instruments. While it lacks the organic reed requirements of instruments like the Bass Clarinet, it offers a similar deep register within the flute family. It is particularly suited for players who require a professional-sounding bass recorder but prefer the low maintenance and structural stability of synthetic materials.
