A Continuation in the Series: Most Classical Music Education is Silly

This is what a yamaha site was actually Bragging about:

By the end of two years in JMC, students have built a substantial vocabulary of solfège, having sung 50 melodies and numerous chord progressions using the I, IV and V7 chords in the keys of C major, G major, F major, D minor and A minor. Aside from developing musicianship, these solfège experiences prepare children to play in these five keys. In fact, children experience singing in a key for approximately one semester prior to playing in that key.

WHAT!? In two years you only learn 5 keys, the subset of which translates to 3 black keys total, no more than 2 in any given scale. It probably takes them such a long time because they have to spend a Whole Semester singing in a key before they can play it. So crazy. Why do classical musicians so deeply believe that detaching music from the physical interface of an instrument is so necessary?
