What range is the English horn in?

The English horn is a double-reed instrument, but it is not a horn at all. It's actually a alto oboe.

This means its range is similar to the alto voice in a choir, generally spanning from around a low D to a high A (depending on the specific instrument and performer).

Here's a more specific breakdown:

* Lowest note: D below middle C (D3)

* Highest note: A above high C (A5)

So, the English horn is a lower-pitched instrument than the standard oboe, giving it a richer, more mellow tone.
