Well I used to think that I played in tune fairly well. Until I played the Holst in Eb, 1st and second movement last night with smart music. I noticed that a few of my notes are either very sharp or very flat, up to 20 cents at the worst (D above tuning C was about 20 flat) What are the best ways to fix this. Just a tuner and play it repetitivly until i play it in tune? or what are some of your guy's ideas.
