It is frustrating isn´t it;I had some students (kids between 12-15 years old) who came to me and said "Hey,thank you!Our teacher in the music lesson wanted to teach us about the church scales and I told him all the half-steps of all the modes..."
I asked:"Did you play music with your music teacher;Did she/he show you the modes with the help of the piano or guitar;"
Ofcourse not.Pure theory.I got a lot of recommandation from parents to other parents to teach their kids too of things like these..they got an A in music in school but dont have the time to practice or let alone to jam 1-2 hours the day as they would like to do...they have to learn stuff they will never ever need.Sad enough this is also true for music.And you know what..we teachers are not cheap.Are we;So we talk about well educated kids from the upper middle-class.Parents who are even a little bit more "progressive",a little bit modern hippie-style from the advertising buisness,doctors,teachers,profs etc...
Well..you shake your head,grab the money and run.
