I've just worked through question 5, number 1 b which asks you to 'write out parts for solo clarinet and solo horn as they would sound at concert pitch. Use the appropriate clef and key signature for each'.
I'm having problems with the key signatures of the clarinet. To me it appears to go from (what I think is) C major to B flat major, but the answer in the book is that it goes to F major.
What am I doing wrong?
