Hi, I am needing the 4 sharp scales and their positions. They are E, A , D, and G. I have the scales but not the positions. I am a great trombone player but was never asked to play these until my allstate competition came up. If you know the positions well and you feel you are confident with them then let me know but if you are unsure in any way please don`t mention anything I am competing against tons of trombones and can`t afford any mistakes thanks.
