Lets say I have a song in the Key of G concert. I play a sax so I would like to lower the pitch of the song 2 half steps so I can play the song on my sax and see the music in the same key. How do I do this? I have been trying to transpose but it seems that when I transpose the key signature changes and then if I try to change the key sig without the transpose the song is transposed. What am I doing wrong? i am totally confused.
