How do I convert C major music into Eb major?

Question

I have to do it for an entire song.

Answer 1

In response to the previous answer, Eb clarinets, alto clarinets, contra-alto clarinets, and bari saxes all share your beloved key.

Answer: It's a fair share of work. You could raise each note 3 half steps (C-Eb, D-F, etc.). If this music is in Finale, I believe you could just change the key of the piece and it does all of this work automatically for you.

Answer 2

rise 5 half steps...ALTO SAX IS AWESOME!!! we get a key all 2 ourselves!!!
