This "Symphony" bass recorder has been designed primarily for ensemble playing. It is pitched in the key of F and its range is from f (below middle C) to g'' (two octaves above). The sound is rich and full throughout the reigster.
The 533B has been specially tailored to be as ergonomically efficient as possible. It has a metal crook so that the keys can be reached more easily, as well as double keys for the F/F# and G/G# for more comfortable fingering. It features a concave bell and a curved windway which allows for improved breath control and hence more expressive playing.
The recorder is finished in a traditional, smart black with ivory trim. It is supplied with a leatherette bag, cleaning rod, joint grease and a sling.
