Any Free EASY software to change the pitch/key of recorded music
My daughter has a science project where she is testing what pitch people prefer. She's going to record herself playing a few bars of music on the piano. Once she has that recording, she wants to use software to change the pitch (raise it or lower it a few notes) so that she can ask her subject pool which pitches they prefer.
Is there any really easy software to use that will accomplish this? basically making it a few notes higher or lower.
