Mr. Petersen is a choir teacher that can be the best person to be around and also the most difficult. You will enjoy his praise if you’re a good singer but if you’re not, be prepared to have little to no attention given to you. He is always trying to recruit more people into his choir, but sometimes at the expense of his current students' experience. He was the most passionate when he didn't have to teach. His love was conducting competent choirs who didn't need help learning their music. When Mr. Petersen is happy, he is so much fun to be around, but when he’s upset, his temper is tough to deal with sometimes. He is a talented man who has great talent. Still, sometimes his temper, along with his struggle to teach complex music, makes his class a rollercoaster of positive and negative emotions. I also recommend that you not get too invested in his extracurricular opportunities because it can be heavily draining. I recommend that you join Mr. Petersen’s choir if you enjoy music and can handle temper tantrums.
