The lowest note of an oboe is B flat (just below Middle C). The lowest note of a cor anglais is an E natural, a diminshed fifth (five notes of a scale, minus a semitone) lower than the oboe's lowest note.
The cor anglais is a transposing instrument pitched in F. This means that the music sounds a fifth lower than written. This has the advantage that the cor anglais player uses fingering as if he were playing an oboe, but it will sound a fifth lower.
The bell (the bit at the end of the instrument) is shaped like a pear. This gives it a less nasal sound (the sound of the cor anglais is less as if played through the nose). The reed is not fixed to a piece of cork like the oboe reed but it is put straight onto the short piece of metal (called a "bocal") at the top of the instrument.
Etymology[change | edit source]
The word "cor anglais" is a French word which literally means "English horn", but the cor anglais is neither English nor a horn. No one is sure how it got its name, but many people think it is because the bocal at the top is curved (the French word for curved, "anglé" is pronounced like the word for English "anglais").
Repertoire[change | edit source]
There are few solo pieces for the instrument, but mostly it is used for solo melodies in slow pieces for orchestra because it can sound very expressive.
