My school music lessons helped me a whole lot more than my art, chemistry, biology, algebraic, trigonometry, French, technical drawing, history lessons. I always assumed that most of the subjects are taught to expand the mind and as an introduction, in the hope that a particular subject will appeal to some students and will pursue it.
I found music lessons to be quite helpful: Bass/Treble clefs; Quavers, Crotchets, Minims etc. Note names and positions on the staff. This all turned out to be very helpful in my musical life.
