Bassoon reed, model Rieger 1A and 2

The Rieger 1A and Rieger 2 bassoon reed models are two widely respected options among bassoonists, each with distinct characteristics that cater to different playing styles and tonal preferences.
The shape of the blade is concave in contrast to the convex cut blades of the Halvorsen reed.

These reeds play with less resistance, produce a brighter tone and are easier to respond to in higher registers. Generally better for faster articulation.
Ultimately, the choice between the Rieger 1A (red Turkish-hat) and Rieger 2 (green Turkish-hat) depends on the individual player's tonal preferences, embouchure strength, and the demands of the musical setting. Many bassoonists keep both models in their arsenal to adapt to varying performance need.
