Yamaha YOB-831 Custom Series European Bore Style Oboe

The YOB-831 offers a 'European' style bore configuration for a focused, pure sound full of rich colors. This inner bore shape is complemented by tapered tone-holes with carefully matched undercutting for accurate intonation and a balanced response. The comfortable amount of back-pressure allows use of free blowing reeds for a wide range of tonal expressions. The keys have been ergonomically re-shaped for optimum comfort and playability while the lever action is carefully regulated to facilitate technique.
