How do you play a cor anglais?

To play a cor anglais, first ensure it is properly assembled and tuned. The instrument is held at an angle, similar to an Oboe, with the left hand on the upper keys and the right hand on the lower keys. To produce sound, place your lips on the double reed and blow gently while using your fingers to cover the appropriate holes or keys to create different notes. Practice breath control and finger coordination to master the instrument's unique timbre and range.
