When playing a Bb Concert Scale , and we played a Bb, what letter would a French Horn player play?

Therefore, for the English Horn or French Horn to play in Concert Pitch, the music must be transposed down a Perfect 5. For F Instruments: So-La is play the French Horn (an F instrument) up on the stage. Ti-Do is playing the piano (a Concert Pitch instrument) down in the Concert Pit.

Explanation:

the answer is counterpoint.

counterpoint definition: "the art or technique of playing a melody or melodies in conjunction with another, according to fixed rules."

counterpoint is present in a lot of baroque music- such as bach (notably his wtc prelude and fugues) and scarlatti, but can also be found in music by mozart, beethoven. it can even be found in music as modern as john williams!
