We Love To Sing, We Sing Of Love, We Are The Choir!

Mrs Lancaster, our choir teacher is unorganized. She explains what she will do, and all the students will get excited but than she does something totally different. She makes decision with no content with the students.A lot of students do not like her and they are gonna stop taking the class because of her.
I would like to have a new teacher, but if possible I would like the guy's choir to have a male teacher. Having a male teacher for a choir of guys would really help. A female teacher is good, but they cannot do the low notes like guys can. Just getting a new teacher who is more prepared, organized and will actually talk with students about decisions will be so much better
